Historical Genomes Reveal Recent Changes in Genetic Health of Eastern Gorillas

Dec. 27, 2018 — The critically endangered Grauer's gorilla has recently lost genetic diversity and has experienced an increase in harmful mutations, according to researchers who sequenced 11 genomes from ... read more

Howler Monkey Study Examines Mechanisms of New Species Formation

Dec. 22, 2018 — A new study of interbreeding between two species of howler monkeys in Mexico is yielding insights into the forces that drive the evolution of new ... read more

Genetics of California Mountain Lions: Research to Inform Future Conservation

Dec. 21, 2018 — Mountain lions in California exhibited strong population genetic structure, and some California populations had extremely low levels of genetic diversity, with some exhibiting estimates as low as the ... read more

Female Penises Evolved Twice in Bark Lice

Dec. 21, 2018 — In a group of bark lice, a penis has evolved twice -- in the females. In their nutrient-scarce environment, 'seminal gifts' are an incentive for females to force mating, leading to the ... read more

Dec. 19, 2018 — Over 450 millipedes, fossilized in 100-million-year-old Burmese amber, were recently discovered by a research team. Using micro-CT technology, the scientists identified 13 out of the 16 main groups ... read more

Stick Insects: Egg-Laying Techniques Reveal New Evolutionary Map

Dec. 19, 2018 — Scientists have created the best map of stick-insect evolution to date by combining DNA analysis and knowledge of their varied egg-laying techniques. The first stick insects flicked or dropped their ... read more

Dec. 18, 2018 — Scientists look to fossils and evolutionary trees to help determine the rate of evolution -- albeit with conflicting results. A new model has helped to resolve these ... read more

Mysteries of the Primrose Unraveled

Dec. 18, 2018 — Plant scientists have succeeded in unraveling the complete genome sequence of the common primrose -- the plant whose reproductive biology captivated the Victorian naturalist Charles Darwin. The ... read more

How Much Are We Learning About the Genome? Natural Selection Is Science's Best Critic

Dec. 18, 2018 — Even as they've struggled to highlight parts of the human genome worth investigating, scientists have wondered how much they're actually learning through the methods they use. Now, two ... read more

Dec. 17, 2018 — Scientists offer novel insights into why and how wind-pollinated plants have evolved from insect-pollinated ancestors, and what it might mean for a potential pollination crisis. They found that ... read more
