Which of the following is closest relative of man
- chimpanzee
- gorilla
- orangutan
- gibbon.
The Correct Option is A
Solution and Explanation
The correct option is(A): chimpanzee.
Humans and chimpanzees are both part of the family Hominidae, which includes great apes. This family is also known as the "hominids." The family Hominidae includes several species, including humans (Homo sapiens), chimpanzees (Pan troglodytes), gorillas (Gorilla gorilla), orangutans (Pongo spp.), and gibbons (Hylobatidae).
However, when considering genetic and evolutionary relationships, chimpanzees are the closest living relatives to humans.

- 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.
