Scientists observe a population of squirrels over a long period of time. The scientists note that after the populations are able

to live together, the black and the brown squirrels are not able to produce fertile offspring. Which explanation best supports the scientists’ observation?
A. The squirrel population experienced more mutations living together than living.
B. The squirrel population did not have enough genetic variation to produce fertile offspring.
C. The squirrel population divided into dominant population and a recessive population of one species.

What logical scientific inference can be drawn from the observation that many different species have homologous structures?
Alexus [3.1K]
<h2>Answer:</h2>

Option C) All species with similar anatomical structures are related.

<h2>Explanation:</h2>
  • Homologous Structure: A homologous structure is an example of an organ or bone that appears in different animals, which are anatomically similar structure demonstrating descent from a common ancestor.
  • All species with similar anatomical structures which means they have  homologous structures and are related as they have evolved from a common ancestor.
  • Homologous structures shows divergent evolution.

Result: Option C is the correct scientific inference for homologous structures.

4. The medium ground finch and the cactus finch are adapted to consume different types of foods. Can you think of a situation in
Sedaia [141]

Answer:

Long beaks of medium ground finches allows them to opt for alternate sources of food in times of extremities while this is not the case with the cactus finches.

Explanation:

The medium ground finches have larger beaks and thus apart from small seeds they can also break open the large seed. In case if the small seeds get scarce, a medium ground finch can still survive by taking advantage of feeding on alternate source of food but small beaked birds such as cactus finches shall die out of starvation.

This adaptation of medium ground finches gives it a survival advantage over the cactus finches

Similarities between seemingly unrelated organisms can be explained by Darwin s theory that organisms come from common ancestors
svetoff [14.1K]

The Darwin's theory of evolution states that the organisms evolve through the process of the natural selection of the favorable genetic variations gradually over time. Through this process of the evolution, new species are developed over time. A single population may give rise to different species. These newly evolved species share similarities will each other as they have the same ancestor.

Hence, the given statement is 'true'.
