What three types of evidence allows us to determine whether organisms shared a common ancestor?

Biology
1 answer:
Anika [276]3 years ago

The evidence of common ancestry is based on study of three   parameters;   fossils record, homologies of various organisms, and study of biogeography. Fossils record   determines the similarity and differences of bones as well as shells of different organisms   over a given period of time.   On the other hand, studying of homologies involves assessment of mitochondrial DNA and other proteins with an aim of finding similarity from one organism to another.  Finally, Biogeography is the assessment of how continental drift might have separated organisms which had got common ancestry and they were living together.

Use the following graph of two theoretical populations (species A and B) to answer the following questions:
avanturin [10]
A) This is predator-prey relationship.

B) Species A is prey and species B is predator.
- If prey population decreases in number, the predator population will also decrease because there is not enough food for predators to survive and vice versa.

- If predator population decreases, the prey population will increase because less prey will be eaten by predators and vice versa.


C) Let population A be Zebras, and population B Lions.

From the graph, at the beginning the there is increase in Lions, as well as in smaller rate in Zebras. At one point, the population of Lions begins to decrease, so they will eat less Zebras. This will allow Zebras to increase population. With more Zebras on the menu, more Lions will eat and increase their chance to survive. This leads to decrease in Zebra population. But again, with less Zebras, the Lion population must decrease allowing Zebra population to increase, and so on.
