Which of the following are the two key concepts of Darwinian theory of evolution?
1 Branching descent and mutation
2 Adaptive radiation and branching ascent
3 Mutation and natural selection
4 Branching descent and natural selection
Explanation:
According to Darwin's theory of evolution, nature selects the fittest. Fitness is based on characteristics which are inherited. Therefore, there must be a genetic basis for getting selected and to evolve. Some organisms are better adapted to survive in an otherwise hostile environment. Adaptive ability is inherited. It has a genetic basis. Fitness is the end result of the ability to adapt and get selected by nature. Therefore, branching descent (inheritance) and natural selection are the two key concepts of Darwin's theory of evolution.So, the correct answer is 'Branching descent and natural selection.

According to Darwinism, fitness level of which category of microbes is highest?
1 Which do not divide but is capable to resist any change in medium
2 Which divide slowly and make few hundred individuals in an hour, all are sensitive to surroundings
3 Which divide and make two types of colonies i.e., resistant and sensitive
4 Which divide fast and make millions of individuals within hours, They have built in variations in terms of ability to utilize a feed component
Explanation:
Fitness according to Darwin refers ultimately and only to the reproductive fitness of an organism. This fitness enables an organism to survive better, produce more progeny, and expand and save its own gene pool.

1 Darwin - French naturalist
2 Lamarck - French naturalist
3 De Vries - French naturalist
4 Malthus - French naturalist
Explanation:
The biological evolution theory of use and disuse of organs was propounded by Lamarck. \(\mathrm{He}\) is a French naturalist who gave the theory of evolution. His theory is also known as Lamarckism.
