A possible example of concept is bird feathers: although obviously valuable for flight, it has been suggested that they were originally an adaptation for insulation

Does natural selection ever favor groups, rather than individuals?

Is perfect adaptation possible?

Adaptations in nature are not perfect, for various reasons. Give atleast one reason

A plant, for example, may be more likely to mutate to a new form with more branches than would a vertebrate because it is easier to produce that kind of change in the development of a plant. What type of constraint is this?

When a lion hunt is successful, does the genus Felis benefits? (Y/N)

In biology, what is the basic level of organization?

Adaptations evolve because they increase the replication of genes. (T/F)

It refers to behaviour by an individual that increases the fitness of another individual while decreasing the fitness of the actor.

In organisms like humans, with separate germ and somatic cell lines, selection between cell lines is a strong force. (T/F)

What form of adaptation does this Papilio butterfly shows?

True or False. The discussion of units of selection aims to find out which level natural selection directly acts on, and which ones it affects only incidentally.

What form of adaptation does the stick insects shows?
