¿Por qué el cuerpo humano tiene esa forma?

The video explores the concept of body plans, highlighting the evolution of symmetry in animals. It discusses the transition from asymmetrical and radial forms to bilateral symmetry, emphasizing the process of cephalization. The Cambrian explosion is noted for its role in diversifying life forms, leading to the emergence of tetrapods. Comparative anatomy is examined, showing similarities across species, and the video concludes with a discussion on future evolutionary changes.
