¿Cómo evolucionaron los peces?

Life evolved in the seas over millions of years, leading to the first vertebrates with primitive spines and skulls. Early fish lacked jaws, but eventually, jaws evolved, revolutionizing feeding and defense. Fish diversified into cartilaginous and bony groups, with bony fish developing swim bladders. Lobe-finned fish marked the transition to land, giving rise to future vertebrate life.

Describe the evolutionary changes that occurred in the muscles of the spine over millions of years.
