New research reveals how octopuses and other cephalopods developed some of the most complex nervous systems in the animal ...

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 adaptation, ...

Octopuses, squid and cuttlefish, collectively known as coleoid cephalopods, have evolved exceptionally large and elaborately structured nervous systems capable of complex behaviors such as ...

Evolution is driven by changes in DNA that sometimes promote adaptation, altering traits like disease resistance or ...

A massive multiomics study of Atlantic salmon and rainbow trout shows that developmental constraints, particularly at the ...

Whole-genome sequencing of 30 Iranian H1N1pdm09 viruses from 2023 to 2025 reveals gradual antigenic drift, preserved vaccine ...

A tiny freshwater snail from New Zealand is giving scientists a glimpse into evolution in motion. University of Iowa biologists have traced the snail's evolutionary history through its genome and ...

Robertsonian chromosomes (ROB) are a type of structurally variant chromosome that is created when two chromosomes fuse together to form an unusual bond. Found commonly in nature, these chromosomes are ...

New research is shaking up our understanding of evolution by revealing that some species may not evolve gradually at all. Instead, scientists discovered that certain marine worms experienced an ...

A groundbreaking study published in PNAS by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not randomly but more frequently where it ...
