Mathematics Shows How to Ensure Evolution
...been a cornerstone of evolutionary theory ever since Darwin. Yet mathematical models of natural selection have often been dogged by an awkward problem that seemed to make evolution harder than...
Animal Mutation Rates Reveal Traits That Speed Evolution
...can begin to answer questions about which traits most influence mutation rates and the pace of evolution. “There are things that affect the rate of evolution, [but] we don’t know...
Evolution ‘Landscapes’ Predict What’s Next for COVID Virus
...that evolution happens on a daily basis. You can actually monitor evolution in real time,” said Samuel Alizon, an evolutionary ecologist at the MIVEGEC laboratory in Montpellier, France. Researchers found...
Flying Fish and Aquarium Pets Yield Secrets of Evolution
New studies reveal the ancient, shared genetic “grammar” underpinning the diverse evolution of fish fins and tetrapod limbs. To escape predators beneath the waves, a flying fish can shoot out...
In Sexy Worms, Inheritance Beyond Genes Can Help Evolution
...it may point to a mechanism that works in tandem with traditional natural selection in shaping the evolution of some organisms. As the new paper in Developmental Cell shows, the...
Electric Fish Genomes Reveal How Evolution Repeats Itself
By studying how electric organs arose in different lineages of fish, scientists gain new insights into a long-standing question of evolutionary biology. Along the murky bottom of the Amazon River,...
Can Darwinian Evolution Explain Lamarckism?
...beneficial to the organism (that is, they are evolutionary adaptations), then the only way that they could have arisen and been maintained over evolutionary time is by Darwinian natural selection....
Biodiversity Alters Strategies of Bacterial Evolution
...how different types of microbial diversity affect the evolution of phage resistance in bacteria. Meanwhile, Harcombe and his colleagues are studying how evolution proceeds in communities where bacterial species cooperate...
Egg Laying or Live Birth: How Evolution Chooses
...the chicken or the egg?” is relatively easy to answer as a question about the evolution of birth in animals. Egg laying almost certainly came before live birth; the armored...
