¿Qué es la cefalización? Planes corporales

The video explores the concept of a head in animals, focusing on spiders and their anatomy. It delves into the evolutionary history of animals, highlighting the role of hox genes in body plan development and cephalization. The specialization of appendages in early animals is discussed, leading to the unique anatomy of spiders, which have a cephalothorax instead of a distinct head. The video concludes with a comparison of anatomy across various species, emphasizing the diversity in nature.
