Question
Chapter 42, Problem 5TY
Summary Introduction
Introduction:
It can be observed in several organisms that they tend to live in a group. The group provided significant evolutionary advantages, which aids in their survival, and hence, maintenance of the population.

Some carnivores will band together when they try to capture prey.
Some individuals can be lookouts.
A large group may be able to fight off a predator that an individual may not have been able to handle.

infanticide is beneficial for the social group
individuals consciously behave in ways that ensure their fitness
individuals act to enhance the survival of their species

Which of the following examples is consistent with this statement? Some lizards in complex tropical forests prefer to hang out on tree trunks and branches, rather than the ground substrate, which has resulted in selection for shorter relative limb length and toe pads that can cling to bark. Ground-burrowing mammals experience greater exposure to dust and increased selection on their respiratory system to filter these particulates. Specialist parasitoids only target a handful of different host/prey types, resulting in a predictable resource and less selection on the ability to learn new resources All of the above Imagine that scientists have just discovered a weird new marine tunicate at extreme depths of the ocean.
