Credit: Illustration by Mauricio Anton Eating Bamboo? It’s All in the Wrist. When is a thumb not really a thumb? When it’s an elongated wrist bone of the giant panda that is used to grasp bamboo. Through its lengthy evolutionary history, the panda’s hand has never developed a truly opposable thumb. Instead, it evolved a thumb-like digit from a wrist bone, the radial sesamoid. This unique adaptation helps these bears subsist entirely on bamboo despite being bears (members of the order Carnivora, or meat-eaters). In a new paper published today (June 30, 2022), scientists report the discovery of the earliest bamboo-eating ancestral panda to have this “thumb.” Surprisingly, it’s longer than its modern descendants. The research was conducted by the Natural History Museum of Los Angeles County’s Curator of Vertebrate Paleontology Xiaoming Wang and colleagues.  While the celebrated false thumb in contemporary giant pandas (Ailuropoda melanoleuca) has been known for more than 100 years, it was not understood how this wrist bone evolved due to a near-total absence of fossil records. A fossil false thumb from an ancestral giant panda, Ailurarctos, dating back 6–7 million years ago was uncovered at the Shuitangba site in the City of Zhaotong, Yunnan Province in south China. It gives scientists a first look at the early use of this extra (sixth) digit–and the earliest evidence of a bamboo diet in ancestral pandas–helping us better understand the evolution of this unique structure.

As an ancestor to modern pandas, Ailurarctos might be expected to have even less well-developed false“thumbs,” but the fossil Wang and his colleagues discovered revealed a longer false thumb with a straighter end than its modern descendants’ shorter, hooked digit. So why did pandas’ false thumbs stop growing to achieve a longer digit? “Panda’s false thumb must walk and ‘chew’,” says Wang. “Such a dual function serves as the limit on how big this ‘thumb’ can become.” Panda gripping vs walking (white bone is the false thumb). Credit: Courtesy of the Natural History Museum of L.A. County Wang and his colleagues think that modern panda’s shorter false thumbs are an evolutionary compromise between the need to manipulate bamboo and the need to walk. The hooked tip of a modern panda’s second thumb lets them manipulate bamboo while letting them carry their impressive weight to the next bamboo meal. After all, the “thumb” is doing double duty as the radial sesamoid–a bone in the animal’s wrist. “Five to six million years should be enough time for the panda to develop longer false thumbs, but it seems that the evolutionary pressure of needing to travel and bear its weight kept the ‘thumb’  short–strong enough to be useful without being big enough to get in the way,” says Denise Su, associate professor at the School of Human Evolution and Social Change and research scientist at the Institute of Human Origins at Arizona State University, and co-leader of the project that recovered the panda specimens. “Evolving from a carnivorous ancestor and becoming a pure bamboo-feeder, pandas must overcome many obstacles,” Wang says. “An opposable ‘thumb’ from a wrist bone may be the most amazing development against these hurdles.” Reference: “Earliest giant panda false thumb suggests conflicting demands for locomotion and feeding” by Xiaoming Wang, Denise F.

Credit: John Bates, Field Museum A family tree encompassing 9,409 bird species has enabled scientists to uncover why the tropics host such a diverse array of colorful birds and how these vibrant colors have evolved and dispersed over time. The color palette of birds visible from your window varies based on your location. In regions far from the Equator, birds typically exhibit drab colors, whereas closer to the tropics, you’ll likely observe a greater variety of colorful feathers. Scientists have been intrigued by the abundance of brilliantly-colored birds in the tropics compared to other areas. They have also questioned the origins of these vibrant birds, pondering whether the colorful feathers evolved in the tropics or if these birds had colorful ancestors that migrated to the region from elsewhere. In a new study published in the journal Nature Ecology and Evolution, scientists built a database of 9,409 birds to explore the spread of color across the globe. They found that iridescent, colorful feathers originated 415 times across the bird tree of life, and in most cases, arose outside of the tropics– and that the ancestor of all modern birds likely had iridescent feathers, too.

Credit: Kate Golembiewski, Field Museum Mechanisms of Coloration and Study Methods “For decades, scientists have had this hypothesis that there are brighter or more colorful species of birds in the tropics,” says Chad Eliason, a research scientist at the Field Museum in Chicago and the paper’s lead author. “We wanted to find the mechanism to help us understand these trends– how these bright colors got there and how they spread across the bird family tree over time.” There are two main ways that color is produced in animals: pigments and structures. Cells produce pigments like melanin, which is responsible for black and brown coloration. Meanwhile, structural color comes from the way light bounces off different arrangements of cell structures. Iridescence, the rainbow shimmer that changes depending how light hits an object, is an example of structural color. Birds-of-paradise in the Field Museum’s collections. Credit: Kate Golembiewski, Field Museum Tropical birds get their colors from a combination of brilliant pigments and structural color. Eliason’s work focuses on structural color, so he wanted to explore that element of tropical bird coloration. He and his colleagues combed through photographs, videos, and even scientific illustrations of 9,409 species of birds– the vast majority of the 10,000-ish living bird species known to science. The researchers kept track of which species have iridescent feathers, and where those birds are found. The scientists then combined their data on bird coloration and distribution with a pre-existing family tree, based on DNA, showing how all the known bird species are related to each other. They fed the information to a modeling system to extrapolate the origins and spread of iridescence. “Basically, we did a lot of math,” says Eliason. Evolutionary Insights and Implications Given how modern species are related to each other and where they’re found, and overall patterns of how species form and how traits like colors change over time, the modeling software determined the most likely explanation for the bird colors we see today: colorful birds from outside the tropics often came to the region millions of years ago, and then branched out into more and more different species. The model also revealed a surprise about the ancestor of all modern birds. For background, birds are a specialized group of dinosaurs– the earliest known bird, Archaeopteryx, lived 140 million years ago. A sub-group of birds called Neornithes evolved 80 million years ago, and this group became the only birds (and dinosaurs) to survive the mass extinction 66 million years ago. All modern birds are members of Neornithes. The model produced by Eliason and his colleagues suggests that the common ancestor of all Neornithes, 80 million years ago, had iridescent feathers that still glitter across the bird family tree. “I was very excited to learn that the ancestral state of all birds is iridescence,” says Eliason. “We’ve found fossil evidence of iridescent birds and other feathered dinosaurs before, ​​by examining fossil feathers and the preserved pigment-producing structures in those feathers. So we know that iridescent feathers existed back in the Cretaceous– those fossils help support the idea from our model that the ancestor of all modern birds was iridescent too.” The discovery that the first Neornithes was likely iridescent could have important implications for paleontology. ”We’re probably going to be finding a lot more iridescence in the fossil record now that we know to look,” says Eliason. While this new study sheds light on how iridescence spread through the bird family tree over the course of millions of years, some big questions remain. “We still don’t know why iridescence evolved in the first place,” says Eliason. “Iridescent feathers can be used by birds to attract mates, but iridescence is related to other aspects of birds’ lives too. For instance, tree swallows change color when the humidity changes, so iridescence could be related to the environment, or it might be related to another physical property of feathers, like water resistance. But knowing more about how there came to be so many iridescent birds in the tropics might help us understand why iridescence evolved.” Reference: “Transitions between colour mechanisms affect speciation dynamics and range distributions of birds” by Chad M.

Researchers mapped 6,000 eye proteins and developed an AI-based “proteomic clock” to predict age. The study revealed accelerated aging in certain diseases and identified proteins linked to Parkinson’s, suggesting an avenue for early diagnosis. The findings could revolutionize precision medicine and clinical trial approaches. An AI-powered proteomic clock from eye fluid reveals disease-driven aging and may enable early Parkinson’s detection. A team of researchers has mapped almost 6,000 proteins from different cell types within the eye by analyzing tiny drops of eye fluid that are routinely removed during surgery. In a study recently published in the journal Cell, the researchers used an AI model to create a “proteomic clock” from this data that can predict a healthy person’s age based on their protein profile. The clock revealed that diseases such as diabetic retinopathy and uveitis cause accelerated aging within specific cell types. Surprisingly, the researchers also detected proteins associated with Parkinson’s disease within eye fluid, which they say could offer a pathway to earlier Parkinson’s diagnoses. Eye as a Window to Diseases “What’s amazing about the eye is we can look inside and see diseases happening in real-time,” says senior author Vinit Mahajan, a surgeon and professor of ophthalmology at Stanford University. “Our primary focus was to connect those anatomical changes to what’s happening at the molecular level inside the eyes of our patients.” The eye is a difficult organ to sample in living patients because, like the brain, it is non-regenerative, and taking a tissue biopsy would cause irreparable damage. An alternative method is to use liquid biopsies—samples of fluid taken from near the cells or tissues of interest. Though liquid biopsies can provide a snapshot of what proteins are present in the region of interest, they have thus far been limited in their ability to measure large numbers of proteins within the small volumes of fluid, and they are also unable to provide information on which cells produced which proteins, which is important for diagnosing and treating diseases. Advanced Protein Mapping and Findings To map protein production by different types of cells within the eye, Mahajan’s team used a high-resolution method to characterize proteins in 120 liquid biopsies taken from the aqueous or vitreous humor of patients undergoing eye surgery. Altogether, they identified 5,953 proteins—ten times the number of proteins previously characterized in similar studies. Using a software tool they created called TEMPO, the researchers were able to trace each protein back to specific cell types. To investigate the relationship between disease and molecular aging, the researchers built an AI machine-learning model that can predict the molecular age of the eye based on a subset of 26 proteins. The model was able to accurately predict the age of healthy eyes but showed that diseases were associated with significant molecular aging. For diabetic retinopathy, the degree of aging increased with disease progression and this aging was accelerated by as much as 30 years for individuals with severe (proliferative) diabetic retinopathy. These signs of aging were sometimes observable before the patient displayed clinical symptoms of the underlying disease and lingered in patients who had been successfully treated. The researchers also detected several proteins that are associated with Parkinson’s disease. These proteins are usually identified postmortem and current diagnostic methods aren’t capable of testing for them, which is one reason Parkinson’s diagnoses are so difficult. Screening for these markers in eye fluid could enable earlier diagnosis of Parkinson’s disease and later therapeutic monitoring. Implications and Future Directions The authors say that these results suggest that aging may be organ- or even cell-specific, which could yield advances in precision medicine and clinical trial design. “These findings demonstrate that our organs are aging at different rates,” says first author and ophthalmologist Julian Wolf of Stanford University. “The use of targeted anti-aging drugs could be the next step in preventative, precision medicine.” “If we’re going to use molecular therapies, we should be characterizing the molecules in our patients,” says Mahajan. “I think reclassifying patients based on their molecular patterns and which cells are being affected can really improve clinical trials, drug selection, and drug outcomes.” Next, the researchers plan to characterize samples from a larger number of patients and a broader range of eye diseases. They also say that their method could be used to characterize other difficult-to-sample tissues. For example, liquid biopsies of cerebrospinal fluid could be used to study or diagnose the brain, synovial fluid could be used to study joints, and urine could be used to study the kidneys.
