Evolution means

abruzzese [7]

Evolution means that populations of organisms change over time.

Explanation:

Evolution refers to the phenomena by which a population develops new traits and becomes more and more fit to survive in a given environment.

Evolution can be studied in two different ways- as a pattern of evolutionary changes and as a process of evolution.

Study of Evolution help us to understand the history of life.

Evidences of evolution support the view that species evolved from common ancestors rather than created separately..

External ear structure that helps to localize the direction from which sound arises

Step2247 [10]

The external ear structure is called the Pinna.

The Pinna helps to channel sound waves into the ear.

Many animals have the ability to move their pinna towards the direction of sound.

I have attached an image of a dog's ear to show you the external structure called the Pinna.

I hope this helps! I'm happy to answer any other questions you might have :)

What is the correct order of the stages of speciation?

guapka [62]

First Stage: Separation

Speciation usually begins when a part of a population becomes separated from the rest of their species.

Second Stage: Adaptation

Adaptation in speciation is quite similar, though the groups may evolve different sets of traits if the environmental conditions differ for each group.

Third Stage: Reproductive Isolation

Reproductive isolation is when groups of a same species are reunited and cannot interbreed with each other anymore, so they are now identified as different species.
