Researchers are trying to recreate an extinct species of the lumbering reptiles by breeding closely related species that contain traces of the lost lineage’s DNA.
Harvesting lab-raised zebrafish based on their size led to differences in the activity of more than 4,000 genes, as well as changes in allele frequencies of those genes, in the fish that remained.
From fish harvests to cottonwood forests, organisms display evidence that species change can occur on timescales that can influence ecological processes.
Guppies transplanted between different communities in Trinidadian streams evolved in response to changes in predation threat in just a few generations.
Using simulations, scientists report that a mixture of termites and plant competition may be responsible for the strange patterns of earth surrounded by plants in the Namib desert.
