Rare evolutionary event detected in the lab

It took nearly a half trillion tries before researchers at The University of Texas at Austin witnessed a rare event and perhaps solved an evolutionary puzzle about how introns, non-coding sequences of DNA located within genes, ...

Genetic analysis uncovers four species of giraffe, not just one

Up until now, scientists had only recognized a single species of giraffe made up of several subspecies. But, according to the most inclusive genetic analysis of giraffe relationships to date, giraffes actually aren't one ...

Origin of a complex life form revealed

Researchers from McGill University have revealed the steps by which two very distinct organisms—bacteria and carpenter ants—have come to depend on one another for survival to become a single complex life form. The study, ...

Genomic analysis reveals true origin of South America's canids

South America has more canid species than any place on Earth, and a surprising new UCLA-led genomic analysis shows that all these doglike animals evolved from a single species that entered the continent just 3.5 million to ...

Study reveals flaws in popular genetic method

The most common analytical method within population genetics is deeply flawed, according to a new study from Lund University in Sweden. This may have led to incorrect results and misconceptions about ethnicity and genetic ...
