There are multiple lines of Evidence that provide support for common ancestry and evolution describing at least three of them in detail. Provide at least one example for each line of evidence

There are multiple lines of Evidence that provide support for common ancestry and evolution are as follows:

1. Anatomy and Embryology:

2. Homologous features:  

3. Fossil record:

There are indeed multiple lines of evidence that provide support for common ancestry and evolution; these include homology, direct observations, the fossil record, and the theory of continental drift.

Explanation:

First off, homology simply refers to similarities amongst organisms due to shared/common ancestry. This can include any observable exterior features of organisms such as their limbs (e.g. the limbs of mammals -- bats, cats, dogs, and humans) or similarities that lie in DNA. For instance, a DNA sequence that has been widely preserved throughout numerous organisms is an app. 180-nucleotide sequence known as the homeobox that is responsible for dictating the body structures of organisms. This category can also include discussion of

Next, direct observations include what Darwin did with "his" finches on the Galapagos Islands and other similar ones, as well as modern experiments in which organisms are seen, as a population, making an adjustment to new environmental conditions to better survive; this is, after all, the idea of evolution. Many experiments w/ these involve an environmental disruption like a drought and birds' beaks.

The fossil record provides us with visual evidence for evolution -- it directly allows us to pinpoint if there are any similar structures amongst organisms and see if there are any vestigial structures from ancestors that remain in organisms that still roam today! There are plenty of examples of this, I'm sure -- just do a basic Internet search.

Lastly, the theory of continental drift -- the idea that at one point the continents were all adjunct but they separated -- provides justification for certain lines of evolution and common ancestry. To be more specific, we may ask the question, "Why are we (humans) so similar to apes and other primates?" The theory of c.d. can help us to answer this question and understand the theory of evolution from the scope of location.

Please feel free to ask any questions.

the correct answer is:

a population changes in response to a change in the environment.
