head and neck evolution

The evolution of the head and neck involves changes in structure and function that have occurred over millions of years. Early vertebrates developed a head to better sense their environment and process food, with bones and muscles for biting, breathing, and sensory input. Over time, these features became more complex, leading to the diverse forms seen in animals today, including humans. The neck evolved as a supportive connection between the head and body, allowing greater mobility and flexibility. Overall, head and neck evolution reflects adaptations that improve survival, feeding, sensing, and interaction with the environment.
