The chronological order of human evolution from early to the recent is

  1. Ramapithecus Homo habilis Australopithecus Homo erectus
  2. Australopithecus Ramapithecus Homo habilis Homo erectus
  3. Ramapithecus Australopithecus Homo habilis Homo erectus
  4. Australopithecus Homo habilis Ramapithecus Homo erectus

Answer

(3) Ramapithecus Australopithecus Homo habilis Homo erectus

Solution

As per NCERT, about 15 mya hominid-like primates such as Dryopithecus and Ramapithecus existed.

⇒ About 2 mya, Australopithecines lived in East African grasslands.

⇒ The first human-like being, Homo habilis, had a brain capacity of 650–800 cc.

⇒ Fossils discovered in Java in 1891 revealed the next stage, Homo erectus, about 1.5 mya, with a brain capacity of about 900 cc.

∴ Order: Ramapithecus Australopithecus Homo habilis Homo erectus

According to Darwin, the organic evolution is due to -

  1. Reduced feeding efficiency in one species due to the presence of interfering species
  2. Competition within closely related species
  3. Intraspecific competition
  4. Interspecific competition

The tendency of population to remain in genetic equilibrium may be disturbed by :

  1. lack of random mating
  2. random mating
  3. lack of migration
  4. lack of mutations
NEET 2013
5

Variation in gene frequencies within populations can occur by chance rather than by natural selection. This is referred to as :

  1. Genetic drift
  2. Genetic load
  3. Genetic flow
  4. Random mating
NEET 2013
6

The process by which organisms with different evolutionary history evolve similar phenotypic adaptations in response to a common environmental challenge is called :

  1. Convergent evolution
  2. Adaptive radiation
  3. Natural selection
  4. Non-random evolution
NEET 2013
7

The eye of octopus and eye of cat show different patterns of structure, yet they perform similar function. This is an example of :

  1. Homologous organs that have evolved due to divergent evolution
  2. Analogous organs that have evolved due to convergent evolution
  3. Homologous organs that have evolved due to convergent evolution
  4. Analogous organs that have evolved due to divergent evolution

8

Random unidirectional change in allele frequencies that occurs by chance in all populations and especially in small populations is known as :-

  1. Genetic drift
  2. Migration
  3. Mutation
  4. Natural selection
NEET 2013 (Karnataka)
9

Genetic variation in a population arises due to :

  1. Reproductive isolation and selection
  2. Mutations only
  3. Mutations as well as recombination
  4. Recombination only
