A Single Gene “Invented” Hemoglobin Several Times
Thanks to the marine worm Platynereis dumerilii, an animal whose genes have evolved very slowly, scientists from CNRS, Université de Paris and Sorbonne Université, in…

Study of flowers with two types of anthers solves mystery that baffled Darwin. Some flowers use a clever strategy to ensure effective pollination by bees,…
The culture-dependent study allowed to isolate a surprisingly large number of diverse and previously unreported bacterial strains from the Tabernas Desert. Microorganisms are the most…
The iconic, prehistoric dire wolf, which prowled through Los Angeles and elsewhere in the Americas over 11 millennia ago, was a distinct species from the…
If you want to understand an ecosystem, look at what the species within it eat. In studying food webs — how animals and plants in…
A pioneering study by University of Bristol researchers finds that the evolution of teeth in the giant prehistoric shark Megalodon and its relatives was a…
Most native species are going locally extinct, while introduced tropical species thrive. The coastline of Israel is one of the warmest areas in the Mediterranean…
A link between evolution over short time frames (microevolution) and long time frames (macroevolution) that could open new approaches to understanding some of biology’s deepest…
Often considered the world’s oddest mammal, Australia’s beaver-like, duck-billed platypus exhibits an array of bizarre characteristics: it lays eggs instead of giving birth to live…
Northeastern Asia has a complex history of migrations and plague outbursts. That is the essence of an international archaeogenetic study published in Science Advances and…
Three papers unveil the extraordinary diversity of animal sex chromosomes. The sex chromosomes genetically define the developmental fate of an embryo to become a male…
Humans feeding leftover lean meat to wolves during harsh winters may have had a role in the early domestication of dogs, towards the end of…
New research by scientists at the University of Bristol explains how a “stop-start” pattern of evolution, governed by environmental change, could explain why crocodiles have…
University of Copenhagen researchers have discovered how mosses became one of our planet’s most widely distributed plants — global wind systems transport them along Earth’s…
The banyan fig tree Ficus microcarpa is famous for its aerial roots, which sprout from branches and eventually reach the soil. The tree also has…
Big bumblebees take time to learn the locations of the best flowers, new research shows. Meanwhile smaller bumblebees — which have a shorter flight range…
A study of more than 1,400 protein-coding genes of fleas has resolved one of the longest standing mysteries in the evolution of insects, reordering their…
New study shows that proteins become biochemically addicted to complex interactions without adaptation. A new study at the University of Chicago has shown that elaborate…
