Drift outside the realm of vertebrates, however, and you can generate an intelligent brain in much weirder ways—from our perspective, anyway. “It’s a Wild West,” she said.

One possibility is that intelligence in vertebrates — animals with backbones, including mammals and birds — evolved once. In that case, both groups would have inherited the complex neural pathways ...

This major evolution was enabled by the emergence of anatomical innovations, such as limbs and the cervical region, specific to tetrapods (four-limbed vertebrates). The neck, absent in fish, allows ...

Blue whales are the biggest animals on Earth, but have you wondered which is the smallest? Scientists have recently described one of the world’s tiniest vertebrates: an adorable miniature toad ...
