Evolution

Cell metabolism is a crucial biological function for all living organisms but understanding how life may have emerged is difficult. And learning some answers may make it possible to learn…

Evolutionary biologists have long considered bird song to be an exclusively male trait, resulting from sexual selection. A new paper says that's not the whole story. The results of their analysis,…

The first life developed in ancient oceans some 3.6 billion years ago, but then nothing much happened. For a billion years, we remained pretty much a layer of slime.  Then 550 million years ago…

A mouse's heart beats about the same number of times in its lifetime as an elephant's, but a mouse only lives for about a year while an elephant will live to be about 70. Why do small plants and…

How did we evolve a face? Vertebrates, backboned animals, come in two basic models: jawless and jawed.  Jawed vertebrates, including us, number over 50,000 species but there are two jawless…

Evolutionary biology sounds exciting - there wouldn't be any movies on the SyFy Channel without Gatoroids and Sharknados and other feats of life science run amok - but in reality you are going to…

Backboned animals, at least the ones with jaws, have four fins or limbs, one pair in front and one pair behind. Thanks to that random prankster known as evolution, these have been modified into a…

In the late 19th century, classification of humans was in vogue and a lot of it was done based on languages and physical characteristics. Physical anthropology and ethno-linguistics created the Aryan…

Where do new genes come from? It's a long standing debate in evolutionary biology but a new paper in Science Express says that new genes are created from non-coding DNA, and more rapidly than…

"Adam", our most common male ancestor, walked the earth 209,000 years ago, 9,000 years earlier than previously believed and within the time frame of his other half "Eve", the genetic maternal…
