Much of the phenotypic variation that is observed within and between species is the result of differences in gene regulation: specifically when, where and how much the genes are expressed. Given the ...

By looking at patterns of gene expression in individual brain cells, researchers at Columbia University showed that despite the anatomical similarities, the neocortex in mammals and the DVR in ...

Epigenetics is the study of various heritable alterations that control gene expression without changing the DNA sequence. 1 The name epigenetics comes from the Greek prefix “epi”, which means on top ...

Gut Microbes may have helped fuel the evolution of large human brains, shaping brain metabolism and gene activity, new ...

A new study from Northwestern University is reshaping how scientists think about brain evolution. The research suggests that ...

The conservation of genome regulatory elements over long periods of evolution is not limited to vertebrates, as previously ...

The recombination between parental chromosomes, a characteristic of sexual reproduction, plays a crucial role in evolution. In mammals, a protein called PRDM9 is essential for this process. In a paper ...

MicroRNAs, whose discovery was recognized with the 2025 Nobel Prize in Physiology or Medicine, are central regulators of gene ...

Two of the traits that set modern humans apart from non-human primates are taller stature and a higher basal metabolic rate. Researchers have identified a genetic variant that contributed to the ...

A new study reveals that changes to the gut microbiome can change the way the brain works.

The origins of human language remain mysterious. Are we the only animals truly capable of complex speech? Are Homo sapiens the only hominids who could give detailed directions to a far-off freshwater ...
