Who is known as the Darwin of $20^{th}$ Century?

Match column I with column II

Tasmanian wolf and placental wolf appear similar due to

Select the odd one w.r.t. homologous organs.

Which of the following statements are incorrect for Natural selection?

(i) Natural selection is based on certain observations which are factual.

(ii) Populations are stable in size except for seasonal fluctuation, means that there had been competition for resources.

(iii) Variation is the most fundamental evolutionary factor and all variations are inherited to the progeny.

(iv) Variations which are heritable and which make resource utilisation better for few (adapted to habitat better) will enable only those to reproduce and leave more progeny.

(v) Herbicides, pesticides etc., resistant organisms/cells are appearing in a time scale of months or years and not centuries.

(vi) Appearance of herbicides, pesticides etc., resistant organisms/cells are examples of evolution by anthropogenic action.

What does the Hardy-Weinberg principle state about allele frequencies in a population?

What does the Hardy-Weinberg principle state about allele frequencies in a population?

What was the brain size of the Neanderthal man?

What phenomenon describes the evolution of different species in a geographical area starting from a common ancestor, as seen in Darwin's finches and Australian marsupials?

What type of moth survived better during the post-industrialisation period due to its ability to camouflage against darkened tree trunks?

Which of the following statements about the origin and evolution of life forms is correct?

Which of the following combinations correctly describes the evolution of life forms on Earth?

Which of the following statements about the process of evolution and natural selection is correct?

Which of the following statements about evolutionary processes is correct?

Which of the following combinations correctly describe aspects of the origin and evolution of life forms on Earth?

Which combination of statements accurately reflects the concept of the origin of life and evolution according to the provided context?

Which of the following statements regarding evolutionary processes and theories is correct?

Which combination of statements about evolution and natural selection is correct?

Assertion (A): Homo sapiens arose in Africa and developed into distinct races after moving across continents.

Reason (R): Ice ages facilitated the migration and diversification of Homo sapiens.

Assertion (A): The Neanderthal man used hides to protect their body.

Reason (R): Homo sapiens arose in Africa and developed into distinct races.

Assertion (A): The anatomical structure of the forelimbs in mammals like whales, bats, cheetah, and humans indicates common ancestry.

Reason (R): Homologous structures result from divergent evolution due to adaptation to different needs.

Assertion (A): Giraffes have long necks because they adapted to forage leaves on tall trees.

Reason (R): Acquired characteristics can be passed on to succeeding generations, leading to evolutionary changes.

Assertion (A): The survival of dark-winged moths during post-industrialisation is an example of natural selection.

Reason (R): Dark-winged moths were better camouflaged against the soot-darkened tree trunks, making them less visible to predators.

Assertion (A): The first organisms to invade land were animals.

Reason (R): Fish with stout and strong fins could move on land and return to water.

Assertion (A): The first organisms to invade land were animals.

Reason (R): Fish with strong fins could move on land and return to water around 350 mya.

Assertion (A): Divergent evolution is demonstrated by the forelimbs of whales, bats, cheetahs, and humans.

Reason (R): Divergent evolution occurs when different species develop similar structures due to similar environmental pressures.
