Question

Which one of the following aspects was found in Darwin’s finches?

• A. Biogeography
• B. Industrial melanism
• C. Biochemical evidence
• D. Embryological evidence

Answer 1

The correct option is A

Biogeography

Darwin’s Finches

1. Darwin observed a different variety of species on a common island.
2. They have the same seed eater ancestors.

Correct option is (a)-

The explanation of the correct option

1. Species restricted to a region develop unique features from the species with which they share a common ancestry, this features can be used as biogeographical evidence.
2. Darwin finches all species evolved on the common island.
3. They have the same common seed-eating ancestors but due to adaptive radiation.
4. They develop different eating habits, which result in different beaks, so darwin finches are biogeography evidence.

The explanation of the incorrect option

Option (b)-

1. Industrial melanism is an example of natural selection.

Option (c)-

1. Certain enzymes and proteins performing a common function in different organisms indicate that these different organisms have a common ancestry.

Option (d)-

1. Embryos can be used as evidence.
2. The similarity in embryos indicates common ancestry.

Final Answer: Biogeography evidence was found in Darwin’s finches.
