In a study published this week in Genome Research, researchers examined the olfactory receptor (OR) repertoire encoded in 13 mammalian species and found that African elephants have the largest number of OR genes ever characterized.
A cross-disciplinary team is calling for public discussion about a potential new way to solve longstanding global ecological problems by using an emerging technology called “gene drives.”
Closely related organisms share most of their genes, but these similarities belie major differences in behavior, intelligence, and physical appearance.
If you’ve ever thought of your circle of friends as a second family, you may be on to something as a new study has found that on a population-wide level friends are more closely related to each other than strangers.
One of the riddles of mammal evolution explained: the strong conservation of the number of trunk vertebrae.
When a pregnant mother is undernourished, her child is at a greater than average risk of developing obesity and type 2 diabetes, in part due to so-called 'epigenetic' effects.
Old World monkeys have undergone a remarkable evolution in facial appearance as a way of avoiding interbreeding with closely related and geographically proximate species
Writing about the weird soft-bodied fossils found in the Burgess Shale in the Canadian Rockies, paleontologist Stephen Jay Gould noted that of 25 initial body plans exhibited by the fossils, all but four were quickly eliminated.
For most of us, crickets are probably most recognizable by the distinctive chirping sounds males make with their wings to lure females. But some crickets living on the islands of Hawaii have effectively lost their instruments and don't make their music anymore.
A new study of how biodiversity arises, by evolutionary biologists at the University of Massachusetts Amherst, shows how a mutation in a single gene during development can lead to different consequences not only in how animals' skull and jaw are shaped, but how this leads to different feeding strategies to exploit different ecological niches.
Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...
