The extinction of the largest dinosaurs to walk the Earth may have played a critical role in creating an environment that ...

"It's been a complete upheaval, says Mark Springer, an evolutionary geneticist at the University of California, Riverside. "We've come up with a very different family tree for mammals." Many ...

In the spirit of “everything is connected,” a new study found that the extinction of the dinosaurs paved the way for the emergence of fruit, which nourished our primate ancestors. Tapping into this ...

Three studies of the brain regions responsible for processing sensory information show that their neurons are and communicate ...

Two studies published in the latest issue of Science have revealed that birds, reptiles, and mammals have developed complex ...

You can see hair only on mammals because it is after the separation from amphibians and turtles. Use the evolutionary tree to find the answer to these questions.

What do phylogenetic trees illustrate? These diagrams don't just organize knowledge of biodiversity - they also show us that living species are the summation of their evolutionary history.

Scientists found that evolution led bird and mammal brains to evolve separately, using different genetic instructions.

The result of this analysis is a phylogenetic tree, which illustrates the branching patterns of evolution, showing common ancestors and the paths of divergence that led to the diversity of life we ...

New research has revealed that birds, reptiles, and mammals have developed complex brain circuits independently, despite sharing a common ancestor. These findings challenge the traditional view of ...
