Genetic Switch for Limbs and Digits Found in Primitive Fish: Before Animals First Walked on Land, Fish Carried Gene Program for Limbs
July 11, 2011 — Genetic instructions for developing limbs and digits were present in primitive fish millions of years before their descendants first crawled on to land, researchers report. The successful swap ... > full story -
Evolution and Domestication of Seed Structure Shown to Use Same Genetic Mutation
July 7, 2011 — For the first time, scientists have identified a mutation in plants that was selected twice -- during both natural evolution and domestication. The mutation has been identified as the source of ... > full story -
Salamanders Spell out Evolution in Action
July 5, 2011 — Lungless salamanders (Ensatina eschscholtzii) live in a horseshoe-shape region in California (a 'ring') which circles around the central valley. New research showed that reproductive isolation of E. ... > full story -
Interaction Is Critical for the Evolution of the Language
July 5, 2011 — An international research group offers evidence for an alternative to the most popular theories on the evolution of ... > full story -
Environs Prompt Advantageous Gene Mutations as Plants Grow; Changes Passed to Progeny
July 1, 2011 — Researchers have found that the environment not only weeds out harmful and useless genetic mutations in plants through natural selection, but actually influences helpful mutations, and that these ... > full story -
New Theory on Origin of Birds: Enlarged Skeletal Muscles
June 22, 2011 — A new theory of the origin of birds, traditionally believed to be driven by the evolution of flight, is now being credited to the emergence of enlarged skeletal muscles in birds. Their upright ... > full story -
Evolution to the Rescue: Species May Adapt Quickly to Rapid Environmental Change, Yeast Study Shows
June 22, 2011 — Evolution is usually thought to be a slow process, something that happens over generations, thanks to adaptive mutations. But environmental change is happening very fast. So, according to a biology ... > full story -
Life-History Traits of Extinct Species May Be Discoverable, Large-Scale DNA Sequencing Data Suggest
June 13, 2011 — Large-scale DNA sequencing data have been used to investigate a long-standing evolutionary assumption -- that DNA mutation rates are influenced by such life-history traits as the time between an ... > full story -
Early Agricultural Piracy Informs the Domestication of Rice
June 9, 2011 — Researchers are casting new light on the origins of rice. By reconciling two theories, scientists show that the domestication of rice occurred at least twice independently but with extensive ... > full story -
Adjustable Valves Gave Ancient Plants the Edge
June 9, 2011 — Controlling water loss is an important ability for modern land plants as it helps them thrive in changing environments. New research shows that water conserving innovations occurred very early in ... > full story
