Many mammals came perilously close to extinction when a massive asteroid hit the earth 66 million years ago, says a study, adding that if a few lucky species did not make it through then mammals may have gone the way of the dinosaurs.
Refuting the notion that turtles are most closely related to lizards and snakes, researchers from the California Academy of Sciences have now reconstructed a detailed “tree of life” linking turtles to dinosaurs.
They pollinate our flowers, vegetables and fruit. They spread deadly diseases. They flash in the summer night. They bore into the wood in our homes. And they serve as supper for birds, reptiles, amphibians and mammals - including people.
An evolutionary race between rival elements within the genomes of primates drove the evolution of complex regulatory networks that orchestrate the activity of genes in every cell of our bodies, reveal new research.
The cells that control our rhythms of sleep and wakefulness may have first evolved in the ocean - hundreds of millions of years ago - in response to pressure to move away from the sun, shows a new study.
A new study shows that our ancient ancestors' ability to find new sources of groundwater during extremely dry periods in Africa millions of years ago may have been the key to their survival and the evolution of the human species.
A new study has revealed that the ability to find the new groundwater sources during extremely dry periods in Africa millions of years ago may have helped ancient ancestors to survive and evolve as species.
