Evolutionary genetics

Researchers find so-called integrons, previously known only in bacteria, in their distantly related microbial relatives. 

Most animals can’t pass on mutations that arise spontaneously throughout their lives—but Elkhorn corals can.

A new study using fairly complete genetic datasets of two phyla of small suspension feeders (Ectoprocta and Entoprocta) reopens the debate on the phylogenetic relationships between them and other animals.

The Swiss Federal Institute of Technology Lausanne evolutionary neurobiologist is using Drosophila to investigate how organisms adapt to novel environments.

Researchers find that evolution can operate on extraordinarily fast timescales.

Epigenetic structures appear to reduce the rate of changes in genes essential for survival and reproduction, a study finds, challenging the notion that mutations are evenly distributed throughout the genome prior to selection.

Genes associated with preterm birth and protecting the fetus from the mother’s immune system appear to be regulated by HAND2.

The Harvard University evolutionary biologist pioneered the use of protein gel electrophoresis to study molecular genetics.  

The largest study to date of the animals’ genetics provides robust evidence that they are adapting to survive a highly lethal, contagious cancer scientists feared would cause their extinction.

The genome sequences of 51 giraffes from all over Africa contribute to the latest attempt in an ongoing pursuit to pin down a species number.

The 12-year-long endeavor reveals Prometheoarchaeum as a tentacled cell, living in a symbiotic relationship with methane-producing microbes.

Biologists’ walk in the woods sparks the creation of a masterful fruit fly field guide.
