Question

The _____ theory is an evolutionary concept that suggests that behaviors that help an organism survive are passed on while weak behaviors are lost.

1. genetic drift2. gene flow3. optimality4. optional

Answer 1

C. Optimality

Step-by-step explanation:

Was graded correct in ody ssey.

ody ssey ware Biology Unit 3, assignment 1, page 5 ( of lesson printoff ) under EVOLUTION the paragraph after the gif of the jaguars running explains Optimality Theory.

"This example ( video of slow fat jags dying off) is similar to the passing on of behaviors, and how behaviors evolve due to the greatest fitness for the species. This is called optimality theory. If a behavior benefits a species more than it costs the species, it will be repeated and passed on for generations. Thus..."

A, and B are from Unit 2, and D is not in the material as relevant and just junk answer to throw us off.

Answer 2

• Option:(1)-The Genetic drift theory is an evolutionary concept that suggests that behaviors that help an organism survive are passed on while weak behaviors are lost.

Step-by-step explanation:

• Genetic Drift

According to this theory, an organisms faces different levels or kinds of environmental factors, which either suppresses or increases the level of a certain allele frequency inside an organisms genetic sequence, which then results in the change in behavior of that organism. And through many generations the changes in behavior may pass on from one to another, as the changes does not occur in a single generation.But, the alleles frequency are suppressed and increased with time, when they face different environmental factors or situations.
