Question

In evolutionary terms, we have more in common with.

• A. A tiger
• B. A chimpanzee.
• C. A spider.
• D. A bacterium.

Answer 1

The correct option is B

A chimpanzee.

The correct option is B.

Explanation of the correct option:

Option B:

1. In evolutionary terms humans and chimpanzees are more similar as they belong to the same order Primate and family Hominidae.
2. They are both mammals.
3. Humans are more similar to Pan troglodytes (chimpanzees).
4. The scientific name of humans is Homo sapiens.
5. Humans and chimps also share a similarity in 98.8% of DNA.
6. Both humans and chimps evolved from a common ancestor which lived 6-7 million years ago.
7. Humans and chimps are close in the phylogenetic tree of mammals.

Explanation of the incorrect option:

Option A:

1. Scientific name of the tiger is Panthera tigris.
2. Tigers are mammals but they belong to a different order Carnivora than humans.
3. They don't have a common ancestor.
4. Hence, humans and tigers are not common based on evolutionary terms.

Option C:

1. Scientifically the spider is known as Araneae.
2. They belong to the phylum Arthropoda and order Araneae.
3. They fall too far from humans on the phylogenetic evolutionary tree.
4. Hence, this is an incorrect option.

Option D:

1. Bacteria are ubiquitous prokaryotic organisms.
2. Whereas humans are eukaryotic organisms.
3. They are not similar to each based on evolutionary terms, hence this is an incorrect option.

Final answer: In evolutionary terms, we have more in common with a chimpanzee.
