A new study theorizes that evolution ticks at different speeds, especially when a big group of organisms first appears.

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

The study of genetic diversity and phylogenetics in donkey breeds has rapidly evolved, providing profound insights into breed origins, evolutionary relationships and the domestication process. By ...

How is skeletal evolution studied? Morphological alterations that contribute to human skeletal structure have been extensively studied in paleoanthropology. Aside from standing height, it has been ...

BEIJING, Jan. 12 (Xinhua) -- Chinese scientists have constructed the most comprehensive genetic map of the world's primary cotton crop to date. This breakthrough not only sheds light on how the plant ...

In a recent study published in Nature Genetics, researchers performed an allelic-level single-cellular multi-omics evaluation of hematopoietic stem/progenitor cells (HSPCs) obtained from individuals ...

The development of hair was of central importance for the evolution of mammals and thus also of humans. However, the evolutionary origin of the genetic program of hair was previously unknown.

The vaginal microbiome, a complex ecosystem inhabited by diverse microbial communities, plays a pivotal role in maintaining reproductive health and protecting against infections. Recent advancements ...

How did horses become some of the greatest athletes in the animal kingdom? Researchers at Johns Hopkins Medicine may have found the answer, pinpointing a genetic mutation and evolutionary process that ...

Genetic researcher Nathan Clark spoke about research his team at the University of Pittsburgh conducted on evolutionary genetics. The seminars are hosted weekly by the University of Wisconsin Genetics ...

In five cases where vertebrates evolved monogamy, the same changes in gene expression occurred each time. In many non-monogamous species, females provide all or most of the offspring care. In ...
