DNA sequencing has changed biology like nothing else since the origin of species theory. In particular, the way we investigate microbial life has fundamentally changed. Today, we are able to sequence DNA with unprecedented ...
Using new gene mapping methods, researchers have found connections between atopic dermatitis (eczema) in dogs and several regions of the genome. Some of the genes identified coincide with genes linked to similar problems ...

An international team of researchers has found evidence of repeated genomic duplications and genetic diversification in protein kinase R (PKR) in mouse-eared bats. In their paper published in the journal Science Advances, ...
The vast majority of vertebrate species living today, including humans, belong to the jawed vertebrate group. The development of articulating jaws during vertebrate evolution was one of the most significant evolutionary transitions ...
