Researchers Discover Link Between Neolithic Farming and Brucellosis

Scientists believe the bacterial infection brucellosis, which affects millions of people every year and causes significant harm to the welfare of livestock, may have evolved along with the development of farming. They came to this conclusion after performing analyses of ancient DNA extracted from an 8,000-year-old sheep bone, in which the Brucella melitensis pathogen was detected.

Genomic Insights Into the Evolution of Gigantism in Cetaceans

Certain gene regions in cetaceans (whales, porpoises, and dolphins) play a role in explaining the remarkable size differences among species, such as the Blue whale (Balaenoptera musculus), which can reach lengths of up to 30 m – almost 10 m longer than a bus – in contrast to the Bottlenose dolphin (Tursiops truncatus), which typically reaches a maximum length of 4 m.
