In the face of pressing threats such as climate change, habitat loss, and illegal trading and hunting, understanding primate genetic diversity has become an urgent priority. Ten groundbreaking papers published in a special issue of Science, including two related studies from Science Advances, shed new light on primate genomes, surpassing previous genomic analyses and providing invaluable insights into the conservation and evolution of these remarkable creatures.
The cornerstone study in the collection, led by Lukas Kuderna and his team, presents whole genome data from an unprecedented 233 primate species, encompassing 86% of primate genera and all 16 families. The dataset enabled the estimation of the human-chimpanzee divergence, revealing a slightly older timeframe than previously thought, ranging between 9.0 and 6.9 million years ago. Furthermore, the study explored the correlation between genomic variation and factors such as climate and sociality, shedding light on the intricate relationship between genetics and primate behavior. Surprisingly, the authors found no global relationship between extinction risk and genetic diversity estimates, challenging previous debates on the subject. The study also provided valuable insights into unique mutations that arose in the human lineage.
Reference genomes for primate species have been sequenced in less than 10% of cases, impeding both research efforts and conservation initiatives. Yong Shao and colleagues address this limitation by presenting high-quality reference genomes for 27 primate species, expanding the available resources for further studies. Notably, they uncovered an unreported increase in the rate of genomic change in the Simiiformes common ancestor, potentially influencing the subsequent diversification of Simiiformes and the evolution of humans.
Iker Rivas-González and his team explored the process of speciation among primate populations, focusing on the phenomenon of incomplete lineage sorting. By accounting for this phenomenon, the researchers were able to construct a primate phylogeny that aligns with fossil estimates, a significant advancement in our understanding of primate evolution.
Hong Wu and colleagues shed light on hybridization in mammalian evolution, an aspect that has often been overlooked. Their study revealed clear evidence of hybridization in the gray snub-nosed monkey, which is derived from a mix between the golden snub-nosed monkey and the ancestor of two extant Rhinopithecus species. The researchers attributed the distinct coat color of the gray snub-nosed monkey to this hybridization event. Similarly, Erik Sørensen and his team investigated baboon populations and discovered evidence of repeated admixture, describing the first instance of a baboon population with a genetic composition derived from three distinct lineages.
In a related study, Bao-Lin Zhang and colleagues compared the reference genomes of 12 macaque species, revealing an ancient hybrid origin of a macaque lineage. Their findings provide a robust strategy and pipeline for identifying hybrid speciation, paving the way for future exploration of similar events.
These innovative studies featured in the special issue of Science significantly enhance our understanding of primate genetic diversity, laying the foundation for more effective conservation efforts and providing valuable insights into our own evolution. As primates continue to face multiple threats, these scientific breakthroughs offer hope for the preservation and protection of these extraordinary creatures.
