A cautionary tale in evolutionary theory is coming straight from the horse’s mouth. When ancient horses diversified into new species, those bursts of evolution weren’t accompanied by drastic ...

Its ancestral tree sprouted numerous branches. Many of these led to species that no longer exist. In other words, horse evolution was never as straightforward as Marsh's smooth fossil sequence ...

an evolutionary geneticist at the University of Copenhagen. That's because the oldest previously sequenced genome was about 10 times younger than the horse's. But the scientists pressed on ...

Scientists in Darwin’s time and through most of the 20th century could only work out the branches of the evolutionary tree of life by looking at the structure and appearance of animals and plants.

The same principle is at play when it comes to evolutionary trees, a study in the journal Communications Biology suggests. Researchers say the method by which animals are sorted into evolutionary ...
