Question

they have eaten and donate it to family members who are unable to feed. which of the following best explains the evolutionary significance of the vampire bat’s food - donating behavior? choose 1 answer: a the behavior increases the chance that the genetic relatives of the vampire bat making the donation will survive. b the behavior increases the chance that the animals from which blood is taken will survive to reproduce. c the behavior increases the chance that the vampire bat donating the food will survive to reproduce.

Explanation:

To determine the evolutionary significance of the vampire bat’s food - donating behavior, we analyze each option:

• Option A: In evolutionary terms, inclusive fitness is important. By helping genetic relatives (family members) survive, the bat is promoting the survival of genes similar to its own. Donating food to family members who can't feed increases the chance these relatives (who share genes) will survive.
• Option B: The bat's food - donating behavior is about helping its own species' relatives, not the animals it takes blood from. The survival of the blood - source animals is not the focus of this bat behavior's evolutionary significance.
• Option C: Donating food to others (even if it's a short - term cost) is more about helping relatives than directly increasing the donor's own survival to reproduce. The act of donating might even put the donor at a slight short - term disadvantage in terms of its own immediate survival resources, so this option is incorrect.

Answer:

A. The behavior increases the chance that the genetic relatives of the vampire bat making the donation will survive.
