British butterfly is evolving to respond to climate change

As global temperatures rise and climatic zones move polewards, species will need to find different environments to prevent extinction. New research, published today in the journal Molecular Ecology, has revealed that climate ...

Selection drives functional evolution of large enzyme families

Researchers at Umeå University, together with researchers at the Institute of Botany, Chinese Academy of Sciences, show in a new study how natural selection drives functional evolution of a large protein family in conifer ...

Evolution keeps sex determination flexible

There are many old wives' tales about what determines a baby's sex, yet it is the tight controls at the gene level that determine an organism's sex in most species. Researchers at Michigan State University have found that ...

How the evolution of tooth enamel tissue unfolded

Researchers at the UZH Center for Dental Medicine have investigated the importance of the Notch pathway for the evolution of tooth morphology. Mutations in this signaling pathway can lead to defective structures in tooth ...

Climatic fluctuations drove key events in human evolution

Research at the University of Liverpool has found that periods of rapid fluctuation in temperature coincided with the emergence of the first distant relatives of human beings and the appearance and spread of stone tools.

Discovering the bigger picture in chromosomes

By mapping various genomes onto an X-Y axis, a team comprised mostly of Kansas State University researchers has found that Charles Darwin and a fruit fly -- among other organisms -- have a lot in common genetically.
