In the 20th century, animals such as mules and ligers that had parents of different species were considered biological flukes, but genetic sequencing is beginning to unravel the critical role of hybridization in evolution.
A mutant protein called Siglec-XII may promote carcinoma progression in humans, but inactivation of its gene seems to avoid the problem, according to a study.
Whiteflies overcome a toxin in plants they eat through the use of the plant’s own genetic protection, likely ferried from plant to insect millions of years ago by a virus.
The physiological demands of that long neck get support from a gene involved in strengthening bones and blood vessels, researchers find after inserting the sequence in mice.
Researchers identify deletions in the N-terminal domain of the spike protein that allow the coronavirus to avoid antibody neutralization and that may contribute to the emergence of new variants.
Over centuries of cultivating Saccharomyces cerevisiae to make dough, bakers have put selective pressure on the species, causing it to diverge into two distinct groups, according to the authors.
A study explains how Zika was present among mosquitoes in Africa for decades without causing the harm to human health seen outside the continent in recent years.
Rather than introducing small chunks of DNA as other viruses do, some giant viruses can contribute more than 1 million base pairs to a host’s genome, broadening the ways in which viruses may shape eukaryote evolution.
A selective advantage may have led the modern human Y chromosome to sweep through the Neanderthal population after it was introduced via interbreeding more than 100,000 years ago.
