color, because it helps the mimic blend into its environment
b
population, because the high number of individuals means more survive
c
toxicity, because when the model is toxic (bad tasting), neither the model nor the mimic will get eaten
d
color, because when the mimic looks like the model, neither will get eaten

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.
