Charles Darwin's theory of evolution generated scientific debate and discussion not only in Darwin's own time, but for decades afterward. In the latter part of the nineteenth century and the until the ...

An international team of researchers has uncovered a remarkable genetic phenomenon in lycophytes, which are similar to ferns and among the oldest land plants. Their study reveals that these plants ...

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 ...

How can we explain the morphological diversity of living organisms? Although genetics is the answer that typically springs to mind, it is not the only explanation. By combining observations of ...

The Indigenous peoples of the Bolivian highlands are survivors. For thousands of years they have lived at altitudes of more than two miles, where oxygen is about 35 percent lower than at sea level.

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

A large-scale population genomic study has shed new light on the evolutionary and domestication history of the button ...

A reduced genome in an island species raises evolutionary questions.

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 ...
