No such thing as a shark? Genomes shake up ocean predator's family tree

Sharks may not form a natural biological group; hexanchiformes might be more closely related to rays and skates than to other sharks, making sharks a paraphyletic group.

Can scientists really resurrect the dodo? Inside the company that says they can

Colossal Biosciences is using ancient DNA and gene editing to resurrect extinct species including dire wolves, woolly mammoths, and dodos, raising questions about the ethics and feasibility of de-extinction technology.

Is a 'selfish gene' making a Utah family have twice as many boys as girls?

Such sex 'distorters' have been discovered - and studied in great depth - in laboratory animals such as mice and flies, in which their effects can be detected through selective breeding. 'If you look, more often than not, you find them,' says Nitin Phadnis, an evolutionary geneticist at the University of Utah in Salt Lake City, who co-led the study.

Daily briefing: This Utah family line might be evidence of 'selfish genes' in humans

Researchers identified a Utah family with seven generations showing twice as many boys as girls, providing first clear evidence of sex-ratio distorting genes in humans.
