Darwin referred to the origin of species as "that mystery of mysteries," and even today, more than150 years later, evolutionary biologists cannot fully explain how new animals and plants arise.
Researchers have created a model that may explain the complexities of the origins of life. Their work, which appears in the Journal of the Royal Society Interface, offers new insights into how RNA signaling likely developed into the modern “genetic code.”
Two Michigan State University evolutionary biologists offer new evidence that evolution doesn’t favor the selfish, disproving a theory popularized in 2012.
In a twist on "survival of the fittest," researchers including biologist Greg Lang have discovered that evolution is driven not by a single beneficial mutation but rather by a group of mutations, including ones called "genetic hitchhikers" that are simply along for the ride.
