Which of the following best describes the expensive tissue hypothesis? brains require more energy, so the gut had to be reduced, and larger brains and tool use led to higher quality diets. increasing body size means that homo neanderthalensis had to include more fat in its diet. brains require more energy, so the gut had to be reduced as brains got bigger. brains require more fat, so the gastrointestinal viscera (gut) had to expand, and hands were needed to acquire more food.

The correct option is this: BRAIN REQUIRES MORE ENERGY, SO THE GUT HAD TO BE REDUCED AND LARGER BRAINS AND TOOL USED LED TO HIGHER QUALITY DIETS.

Explanation:

The Expensive Tissue Hypothesis is an hypothesis that relates the relationship between the brain and the gut during the period of human evolution. The hypothesis submits that in order for human to develop a larger brain without increasing his metabolic rate, he has to use less energy on other expensive tissues such as gut. Thus, the hypothesis suggests that human evolve a larger brain and make up for this development by evolving a gut that need less energy and by eating higher quality foods that are obtained by mean of using agricultural tools.
