Which evidence of evolution related to Darwin's finches:
- Evidences from biogeographical distribution
- Evidences from comparative anatomy
- Evidences from embryology
- Evidences from palaeontological
The Correct Option is A
Solution and Explanation
Evidence related to Darwin's finches primarily comes from biogeographical distribution. Charles Darwin's observations of finches on the Galápagos Islands played a crucial role in the development of his theory of evolution by natural selection. He noted that different species of finches on various islands had distinct beak shapes and behaviors adapted to their specific environments. This observation highlighted the role of geographical isolation and adaptation in the evolution of species.
So, the correct option is (A): Evidences from biogeographical distribution

- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

Evolution
Evolution is a process that occurs in changes in the genetic content of a population over time. Evolutionary change is generally classified into two: microevolution and macroevolution. The process of changes in allele frequencies in a population over time is a microevolutionary process. Three main mechanisms that cause allele frequency change are natural selection, genetic drift, and gene flow. On the other hand, macroevolution refers to change at or above the level of the species.
