Humans didn't cause problems for everything we get blamed for but DNA evidence in a paper suggests that the ancient New Zealand megaherbivore, moa, a distant relative of the Australian Emu, did go…

Researchers have found the earliest fossil evidence for the presence of bone marrow in the fin of a 370 million-year-old fish, Eusthenopteron, a Devonian lobe-finned fish from Miguasha in Canada that…

A new study finds that sea anemones display a genomic landscape with a complexity of regulatory elements similar to that of fruit flies or other animal model systems, which suggests that this…

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…
