Fourteen pairs of appendages likely served a double role – providing the animal with oxygen and allowing it to move about. Credit: Nicholas Strausfeld Rare fossils preserving the brains of creatures living more than half a billion years ago shed new light on the evolution of arthropods. Exquisitely preserved fossils left behind by creatures living more than half a billion years ago reveal in great detail identical structures that researchers have long hypothesized must have contributed to the archetypal brain that has been inherited by all arthropods. Arthropods are the most diverse and species-rich taxonomic group of animals and include insects, crustaceans, spiders and scorpions, as well as other, less familiar lineages such as millipedes and centipedes. The fossils, belonging to an arthropod known as Leanchoilia, confirm the presence – predicted by earlier studies in genetics and developmental biology of insect and spider embryos – of an extreme frontal domain of the brain that is not segmented and is invisible in modern adult arthropods. Despite being invisible, this frontal domain gives rise to several crucial neural centers in the adult arthropod brain, including stem cells that eventually provide centers involved in decision-making and memory. This frontal domain was hypothesized to be distinct from the forebrain, midbrain and hindbrain seen in living arthropods, and it was given the name prosocerebrum, with “proso” meaning “front.” Side view of Leanchoilia showing its distinctive head shield followed by 11 segments ending in a triangular “tail.” Scale bar is 2 millimeters. Credit: Nicholas Strausfeld Described in a paper published on August 19, 2021, in the journal Current Biology, the fossils provide the first evidence of the existence of this discrete prosocerebral brain region, which has a legacy that shows up during the embryonic development of modern arthropods, according to paper lead author Nicholas Strausfeld, a Regents Professor of Neuroscience at the University of Arizona. “The extraordinary fossils we describe are unlike anything that has been seen before,” Strausfeld said. “Two nervous systems, already unique because they are identically preserved, show that half a billion years ago this most anterior brain region was present and structurally distinct before the evolutionary appearance of the three segmental ganglia that denote the fore-, mid- and hindbrain.” The term ganglion refers to a system of networks forming a nerve center that occurs in each segment of the nervous system of an arthropod. In living arthropods, the three ganglia that mark the three-part brain condensed together to form a solid mass, obscuring their evolutionary origin as segmented structures. Fossils of Brain Tissue are Extremely Rare Discovered in deposits of the Kaili formation – a geological formation in the Guizhou province of southwest China – the fossilized remains of Leanchoilia date back to the Cambrian period, about 508 million years ago. The Kaili fossils occur in sedimentary rock that has high concentrations of iron, the presence of which probably helped preserve soft tissue, which subsequently was replaced by carbon deposits.

The blue shaded areas indicate preserved gut tissue. Scale bar represents 2 millimeters. Credit: Nicholas Strausfeld “The Kaili fossils open a window for us to glimpse the body plan evolution of animals that lived more than half a billion years ago,” said the paper’s first author, Tian Lan of the Guizhou Research Center for Palaeobiology at Guizhou University in China. “For the first time, we now know that arthropod fossils of the Kaili formation have the potential to preserve neural tissue that show us the primitive brain of the early stem arthropod existing at the dawn of the animal world.”  “Nervous systems, as other soft tissues, are difficult to fossilize,” added co-author Pedro Martinez of the Universitat de Barcelona and Institut Catalá in Barcelona, Spain. “This makes the study of the early evolution of neural systems a challenging task.” The fossils also shed new light on the evolutionary origin of two separate visual systems in arthropod evolution: pairs of front-facing eyes or sideward looking eyes, the descendants of which are still present in species living today. Many arthropods, including insects and crustaceans, have a distinct bilateral pair of faceted compound eyes and another set of less obvious eyes – with more primitive architecture – known as nauplius eyes, or ocelli. These are structurally similar to the principal eyes of spiders and scorpions. These simpler eyes correspond to the prosocerebrum’s forward eyes in Leanchoilia, in line with evidence obtained by previous studies analyzing gene expression patterns during embryonic development of living arthropods. View of the anterior part of the fossil photographed in direct light and showing the dark traces of sideward eyes, prosocerebrum (the palest traces) and segmental ganglia. The scale bar equals 2 millimeters. Credit: Nicholas Strausfeld Leanchoilia‘s sideward eyes, on the other hand, relate to the protocerebrum, which is the segmental ganglion defining the arthropod forebrain, lying just behind the prosocerebrum. In living arthropods, the protocerebrum provides the compound eyes of insects and crustaceans, or the lateral single-lens eyes of arachnids, centipedes and millipedes. The visual centers serving those eyes also belong to the brain’s protocerebral region. Strausfeld explained that in living arthropods, the protocerebrum, or forebrain, has incorporated – in a way, swallowed up – the ancient centers provided by the prosocerebrum, so that it is no longer discernible as a distinct anatomical entity. The fossils are so well-preserved that they demonstrate that in addition to frontward eyes, the prosocerebrum has also given rise to ganglia associated with the labrum, or “upper lip,” of modern arthropods. The fossils also confirm an earlier hypothesis suggesting that the labrum must have originally evolved from the grasping appendages of Radiodonta, a group of stem-arthropods that were top predators during the Cambrian period. “When compared with other, similar fossil material belonging to more advanced lineages, the organization of the Leanchoilia brain demonstrates that the ganglionic arrangement of the early brain underwent condensation and fusion of its components, which explains why in living species the prosocerebrum cannot be individually distinguished,” Strausfeld said. Implications for Brain Evolution in Vertebrates In addition to closing a century-old gap in the understanding of arthropod brain evolution, the findings have important implications for the early evolution of vertebrate brains, Strausfeld said. Although simple, fishlike animals existed at the same time as these now-fossilized arthropods, there are no convincing fossils of their brains and, thus, neither fossil evidence nor anatomical evidence for a prosocerebrum in vertebrates. Yet, modern studies show that genes defining the fore- mid- and hindbrains of, for example, mice correspond to genes defining the three ganglionic divisions of the arthropod brain. And in vertebrates, certain crucial centers involved in decision making and in learning and memory have some genetic correspondences with the higher centers in the arthropod brain, which originated in the ancient arthropod prosocerebrum.   Thus, it is plausible that even earlier than the Cambrian period, possibly even before the evolution of segmentally organized body plans, the common ancestor of both vertebrates and invertebrates possessed basic circuits for simple cognition and decision making. And while an ancient prosocerebral-like brain might have been present in the very early ancestors of vertebrates, no such fossil has even suggested evidence for a discrete, nonsegmental domain. “Nevertheless, one can reasonably speculate that vertebrates have embedded in their ‘modern’ brains parts of an ancient, non-segmented brain that has so far only been demonstrable in an early arthropod, such as Leanchoilia,” Strausfeld said.

The Greater mouse-tailed bat flies through the night sky, searching for insects. Credit: Jens Rydell When they emerge at night in large numbers, bats avoid colliding with each other by adjusting both their flight patterns and the way they use echolocation. Aya Goldshtein, Omer Mazar, and Yossi Yovel have spent many evenings observing bats outside cave entrances. Still, the sight of thousands of bats bursting out into the night sky, sometimes in such dense numbers that they look like a flowing liquid, never fails to amaze them. What surprises the scientists even more is what they don’t see. “The bats don’t run into each other,” says Goldshtein from the Max Planck Institute of Animal Behavior, “even in colonies of hundreds of thousands of bats all flying out of a small opening.” A “nightmare” cocktail party How bats manage to avoid crashing into one another as they emerge in massive swarms to forage at night has long puzzled scientists. Many bats rely primarily on echolocation to sense their surroundings. They emit calls and then listen for the returning echoes, which help them build a mental map of their environment. But when thousands of bats are echolocating at the same time, especially in a tight space, the overlapping calls should interfere with one another. This phenomenon, known as “jamming,” was expected to overwhelm the bats’ ability to navigate and lead to frequent collisions. Bats emerge from roosts every evening often in extraordinary numbers. Credit: Eran Amichay Yet collisions outside caves are so rare that “you’re almost excited when you witness one,” says Goldshtein. For years, researchers have been trying to understand how bats overcome this problem, often compared to the “cocktail party nightmare,” where background noise makes it nearly impossible to focus on a single voice. One approach scientists took was to study how bats echolocate in groups. In laboratory settings, they found that individual bats in small groups tend to use slightly different frequencies for their calls. In theory, this frequency separation could reduce the effects of jamming. Was this the answer? Yovel says that past studies like these are important stepping stones, but they have fallen short of providing a compelling answer to the cocktail party mystery because of a crucial missing piece. “No one had looked at this situation from the point of view of an individual bat during emergence. How can we understand a behavior if we don’t study it in action?” Video showing the evening emergence of thousands of Greater mouse-tailed bats, as they take to the sky in search of insects. The video shows rare collisions of bats in mid air. Credit: Yossi Yovel and Eran Amichay Stepping into the bat cave For the first time, Goldshtein and colleagues have collected data from wild bats emerging from a cave at dusk. They used a combination of high-resolution tracking, developed by Ran Nathan and Sivan Toledo, ultrasonic recording, and sensorimotor computer modeling—all of which allowed the researchers to step into the bats’ sensory world as the animals squeezed out of the cave opening and flew through the landscape to forage. The team, which was led by scientists from Tel Aviv University, studied greater mouse-tailed bats in Israel’s Hula Valley. Over two years, they tagged tens of bats with lightweight trackers that recorded the bats’ location every second. Some of these tags also included ultrasonic microphones that recorded the auditory scene from the individual bat’s point of view. Each year, data was collected on the same night that bats were tagged. Greater mouse-tailed bat (Rhinopoma microphyllum). Credit: Jens Rydell A caveat: the tagged bats were released outside the cave and into the emerging colony, meaning that real data were missing at the cave opening when density is highest. The team filled in this gap with a computational model that was developed by Omer Mazar and simulated emergence. The model incorporated data collected by the trackers and microphones to recreate the full behavioral sequence starting from the entrance of the cave and ending after bats had flown two kilometers through the valley. “The simulation allows us to verify our assumptions of how bats solve this complex task during emergence,” says Mazar. Sidestepping a sonic dilemma And the picture that emerged was remarkable. When exiting the cave, bats experience a cacophony of calls, with 94 percent of echolocations being jammed. Yet, within five seconds of leaving the cave, bats significantly reduced the echolocation jamming. They also made two important behavioral changes: first, they fanned out from the dense colony core while maintaining the group structure; and second, they emitted shorter and weaker calls at higher frequency. The researchers suspected that bats would reduce jamming by quickly dispersing from the cave. But why did bats change their echolocation to a higher frequency? Wouldn’t more calling only increase the problem of jamming and therefore collision risk? To understand that result, the authors had to approach the scene from a bat’s point of view. Says Mazar: “Imagine you’re a bat flying through a cluttered space. The most important object you need to know about is the bat directly in front. So you should echolocate in such a way that gives you the most detailed information about only that bat. Sure, you might miss most of the information available because of jamming, but it doesn’t matter because you only need enough detail to avoid crashing into that bat.” In other words, bats change the way they echolocate to gain detailed information about their near neighbors—a strategy that ultimately helps them to successfully maneuver and avoid collisions. The authors emphasize that this unexpected result of how bats solve the cocktail party dilemma was made possible by studying bats in their natural environment as they perform the relevant task. “Theoretical and lab studies of the past have allowed us to imagine the possibilities,” says Goldshtein. “But only by putting ourselves, as close as possible, into the shoes of an animal will we ever be able to understand the challenges they face and what they do to solve them.” Reference: “Onboard recordings reveal how bats maneuver under severe acoustic interference” by Aya Goldshtein, Omer Mazar, Lee Harten, Eran Amichai, Reut Assa, Anat Levi, Yotam Orchan, Sivan Toledo, Ran Nathan and Yossi Yovel, 31 March 2025, Proceedings of the National Academy of Sciences.

Artistic reconstruction of Utaurora comosa from the Wheeler Formation, Utah, USA (Cambrian: Drumian). Credit: Artwork by F. Anthony Utaurora comosa has been reclassified from a radiodont to an opabiniid, revealing new insights into Cambrian arthropod diversity and evolution. In his book Wonderful Life, the late Stephen Jay Gould, former professor in the Department of Organismic and Evolutionary Biology at Harvard, popularized the “weird wonder” stem-group arthropods Opabinia and Anomalocaris, discovered in the Cambrian Burgess Shale, turning them into icons in popular culture. While the “terror of the Cambrian’ Anomalocaris – with its radial mouth and spiny grasping appendages – is a radiodont with many relatives, the five-eyed Opabinia – with its distinctive frontal proboscis – remains the only opabiniid ever discovered. That is, until now. An international team of researchers led by Harvard University confirm that a specimen previously considered a radiodont is in fact an opabiniid. The new study in Proceedings of the Royal Society B used novel and robust phylogenetic methods to confirm Utaurora comosa as only the second opabiniid ever discovered and the first in over a century. Utaurora comosa from the Wheeler Formation, Utah, USA (Cambrian: Drumian). Holotype and only known specimen, accessioned at the Division of Invertebrate Paleontology in the Biodiversity Institute at the University of Kansas. Credit: Photograph by S. Pates Utaurora comosa, found in the 500 million-year-old middle Cambrian Wheeler Formation of Utah, was first described in 2008 as a radiodont. Co-lead author Stephen Pates, former postdoctoral fellow in the Department of Organismic and Evolutionary Biology (OEB) at Harvard, first encountered the specimen at the University of Kansas Biodiversity Institute & Natural History Museum while a graduate student. Pates was studying the diversity of radiodonts and felt this specimen did not exactly fit with a true radiodont. Upon joining senior author Professor Javier Ortega-Hernández’s lab in OEB, Pates worked with co-lead author Jo Wolfe, postdoctoral fellow in OEB who studies the relationships of fossil and living arthropods, to determine where Utaurora best fit in the tree of life. Morphological Characteristics of Utaurora Opabiniids are the first group to have a posterior-facing mouth. Their dorsal intersegmental furrows are precursors to full body segmentation and their lateral swimming flaps precursors to appendages. Utaurora shares characters and morphology with both radiodonts and Opabinia. While Utaurora’s anterior structure and eyes were poorly preserved – Opabinia is most recognizable from its frontal proboscis and five eyes, the intersegmental furrows along the back and the paired serrated spines on the tail were fully observed.  Limited morphological observations led Pates and Wolfe to use phylogenetic analysis comparing Utaurora with 43 fossils and 11 living taxa of arthropods, radiodonts, and other panarthropods. “The initial phylogenetic analysis showed it was most closely related to Opabinia,” Wolfe said. “We followed up with more tests to interrogate that result using different models of evolution and data sets to visualize the different kinds of relationships this fossil may have had.” Unlike Opabinia, which was discovered in the Cambrian Burgess Shale of British Columbia in Canada, Utaurora was found in Utah and, though still Cambrian, is a few million years younger than Opabinia. “This means Opabinia was not the only opabiniid, Opabinia was not as unique a species as we thought,” Pates said. Revisiting the Dinocarid Concept and Evolutionary Insights When Utaurora was first described as a radiodont in 2008 scientists thought opabiniids and radiodonts formed a monophyletic group called ‘dinocarids.’ But over the past 10 to 15 years scientists have discovered over 10 new species of radiodonts, making it possible to see that opabiniids and radiodonts are slightly different. “We also have more phylogenetic tools to interrogate our results,” Pates said. “Based on the morphology alone you could make a case for Utaurora being a weird radiodont and also for bringing back the ‘dinocarid’ concept. But our phylogenetic dataset and analyses supported Utaurora as an opabiniid in 68% of the trees retrieved by analyzing the data, but only in 0.04% for a radiodont.” “Wonderful Life and the description of these fossils happened before current evolutionary paradigms. The similarities between Opabinia and Anomalocaris weren’t really understood yet,” Wolfe said. “Now we know that these animals represent extinct stages of evolution that are related to modern arthropods. And we have tools beyond qualitatively comparing morphological features for a more definitive placement within the  animal tree of life.” Reference: “New opabiniid diversifies the weirdest wonders of the euarthropod stem group” by Stephen Pates, Joanna M.
