Page 7: Research news on evolution

Evolution, as a scientific topic, encompasses the study of heritable change in populations of organisms over successive generations, driven primarily by mechanisms such as mutation, natural selection, genetic drift, gene flow, and recombination. It investigates how genetic variation arises and is differentially propagated, leading to adaptation, speciation, and macroevolutionary patterns observable in phylogenies and the fossil record. Research in this area integrates population genetics, comparative genomics, quantitative genetics, and developmental biology to elucidate processes shaping genetic architecture, fitness landscapes, and phenotypic diversity, as well as the tempo and mode of evolutionary change across different ecological and genomic contexts.

How evolution explains autism rates in humans

A paper in Molecular Biology and Evolution finds that the relatively high rate of autism-spectrum disorders in humans is likely due to how humans evolved in the past. The paper is titled "A general principle of neuronal evolution ...

Genomic analysis shows how cavefish lost their eyes

Small, colorless, and blind, amblyopsid cavefishes inhabit subterranean waters throughout the eastern United States. In a new study, Yale researchers reveal insights into just how these distinctive cave dwellers evolved—and ...

Genomics can help insect farmers avoid pitfalls of domestication

Insects are becoming increasingly popular to grow on farms as feed for other animals, pet food and potentially as food for people. The process of bringing a wild animal into an artificial environment, known as domestication, ...

How the genome defends itself against internal enemies

An international research team has deciphered a mechanism of the evolutionary arms race in human cells. The findings provide insights into how mobile elements in DNA hijack cellular functions—and how cells can defend themselves ...
