Answer 1

The correct answer is "efficient bipedalism...efficient thermoregulation."

Step-by-step explanation

Efficient bipedalism was a critical adaptation of H. erectus, which allowed them to travel longer distances and forage for food more efficiently. This adaptation also freed up their hands, allowing them to carry tools and weapons, which further increased their ability to survive and thrive.

Efficient thermoregulation was another important adaptation that allowed H. erectus to maintain a stable body temperature, which was crucial for their survival in diverse environments. This was achieved through a combination of physical adaptations, such as increased sweat gland density, and behavioral adaptations, such as seeking shade during the hottest parts of the day.

These two adaptations were likely subjected to strong selective pressure and may have been part of a biocultural feedback loop, as they allowed H. erectus to expand their range and explore new environments, which in turn may have influenced the development of their culture and technology.
