Researchers complete mollusk evolutionary tree
Mollusks have been around for so long (at least 500 million years), are so prevalent on land and in water (from backyard gardens to the deep ocean), and are so valuable to people (clam chowder, oysters on ...

The living fossils of brain evolution
(Phys.org) -- In the course of its evolution, the architecture of the mouse brain may have barely changed. Similar to the tiny ancestors of modern mammals that lived about 80 million years ago, nerve cells ...

Plant enzyme's origins traced to non-enzyme ancestors
(Phys.org) -- As plants began to transition from aquatic habitats to dry land some 500 million years ago, their needs changed. Those primitive ancestors of modern plants were ill-equipped to survive in a dry, sunlight-blasted ...

Living longer -- variability in infection-fighting genes can be a boon for male survival
Females of mammals (including humans) tend to outlive males, a circumstance that is usually attributed to males´ more aggressive and hence energy-depleting behaviour, especially when they compete for females. This might ...
