Which of the following set contains only homologous organs?
1 Whales flipper, horses forelimb, human hand
2 Wings of butterfly, crow and insect
3 Horses forelimb, insect wing, human hand
4 Vermiform appendix, body hair, and patella
Explanation:
Homologous organs are morphologically same and have similar internal structure and perform different function. For example . The flapper of a whale, the forelimb of a horse and the hand of a human are all homologous organs.

The mode of speciation mediated by geographical isolation is referred to as
1 Adaptive radiation
2 Allopatric speciation
3 Parapatric speciation
4 Sympatric speciation
Explanation:
Allopatric speciation occurs when population of a species become geographically isolated from each other, leading to reproductive isolation and ultimately the formation of distinct species. Then term " allopatric " means " different homeland". - Allopatric speciation occur by many type geographical isolation, genetic divergence reproductive isolation, speciation, this process helps explain the incredible diversity of life on earth, as isolated populations adapt to their unique environment and gradually evolve into distinct specie.

Natural selection where more individuals acquire specific character value other than the mean character value, leads to
1 Random change
2 Stabilising change
3 Directional change
4 Disruptive change
Explanation:
In directional natural selection more individuals acquire value other than the mean character value. - No random change in natural selection. - Nature selection leads to stabilization when more individual acquire mean character value. - In disruptive change more individuals acquire peripheral character value at both ends of the distribution curve.

Flippers of Penguins and Dolphins are examples of
1 Convergent evolution
2 Industrial melanism
3 Natural selection
4 Adaptive radiation
Explanation:
A Convergent evolution is defined as the process in which organism evolve similar body forms, coloration and adaptation. Flipper of penguins and dolphins have different ancestor but have similar traits.
