Answer:
Biological species contest.
Explanation:
Different species concept are introduced to describe the exact definition and classification of species. Some species concept are biological species contest, morphological species concept and ecological species contest.
According to biological species contest, the group of individual that can breed among themselves and not with the other group. Here, the Drosophila species has been classified by the biologist depending on their mating ability to their group of individual only.
Thus, the answer is biological species contest.

Multicellular organisms - composed of several different cells: Cells in these organisms differ in relation to the function to be performed.
The cells in these organisms are growing, developing, and reproducing.
The cells differ in shape, size, and role they have in the organism.

When Charles Darwin considered wings of birds, apart from his famous proposal he also predicted that fossils will be found with structures that are intermediate between early and modern form.
Answer: Option C
<u>Explanation:</u>
Charles Darwin was basically referring to transitional Fossil while considering Wings of bird. So what are transitional fossil? They are the fossil remains of both the ancestral group and the descendant group.
Since we don’t have enough record of the fossils, it is very difficult to know the accuracy of transitional fossil. However, we do have some record of fossils from which we can gather enough evidence of how the fossils where earlier and how it evolved over a period of time.
The fossil record gives evidence of extinct species. The fossil record shows that organisms always remain the same. Which best describes how the fossil record is
