Birds are the most diverse land vertebrate on the planet, and now scientists have constructed a complete evolutionary tree of the 11,000 or so known species. This data came from hundreds of studies ...

Paleorex is back on Bored Panda with his detailed, science-based creatures, showing us how animals like big cats, birds, and reptiles might evolve in the future. In this article, we’re featuring even ...

Life depends on genes being switched on and off at exactly the right time. Even the simplest living organisms do this, but usually over short distances across the DNA sequence, with the on/off switch ...

This 30-million-year-long gap is actually rather helpful to Darwin. It means that there was plenty of time for the ancestor of complex animals to evolve, unhurriedly splitting to make new species ...

To understand how organisms are related, researchers use molecular information to construct phylogenetic trees. Most of the time, scientists use thousands of protein-coding sequences to determine ...

Animals of the Cambrian period went through one of the greatest evolutionary surges in history, known as the Cambrian Explosion. Animals of the Cambrian period likely began as worms or worm-like ...
