The study found that bird species who nest in tree cavities have independently evolved heightened aggression across lineages, particularly in females.

Birds fighting for nesting spots show repeated aggression and shared brain gene patterns, suggesting evolution may repeat.

The two species, however, have very little else in common – in fact, they are further apart on the evolutionary tree than cats and dogs ... It has been speculated that the behaviour serves to dislodge ...

A research team has created a comprehensive evolutionary tree of all bird species, integrating data from hundreds of studies ...

The genome structure—how genes are organized within DNA sequences in an organism—is fundamental to the processes and ...

By combining data on all known bird species, this tree is the most impressive snapshot yet of one of Earth’s most ...

Evolutionary genetics is the study of how genetic variation leads to evolutionary change. It includes topics such as the evolution of genome structure, the genetic basis of speciation and ...

Comb jellies "could repurpose [their] genetic toolkit in different ways like a Swiss knife," said the researchers.

Genes aren’t destiny. The ARCH × Φ model explains how brain wiring, motivation, culture, and timing interact—multiplying risk ...
