Select the correct for below statement ? (a) Natural selection is base...
**Correct answer: (3) only a, c and d**
Explanation:
(a) Natural selection is based on certain observations which are factual.
- Natural selection is a key mechanism of evolution, proposed by Charles Darwin. It is based on the observation that individuals with favorable traits are more likely to survive and reproduce, passing on those traits to future generations.
- These observations are factual and have been supported by numerous studies and evidence.
(b) Acquired characters do not inherit, according to Lamarck.
- Lamarck's theory of evolution, also known as Lamarckism, proposed that acquired characteristics during an organism's lifetime could be inherited by the next generation.
- However, this idea has been disproven by modern genetics and the understanding of inheritance through DNA. Acquired characteristics are not passed on to offspring.
(c) The essence of Darwinian theory about evolution is natural selection.
- Charles Darwin's theory of evolution by natural selection states that species evolve over time through the process of natural selection.
- Natural selection acts on heritable variations within a population, favoring traits that increase an organism's chances of survival and reproduction. This results in the gradual change and adaptation of species over generations.
(d) Hugo de Vries believed in single-step large mutations.
- Hugo de Vries was a Dutch botanist who proposed the theory of mutationism, which suggested that new species arise suddenly through large-scale changes or mutations in the genetic material.
- De Vries believed that evolution occurred through single-step large mutations, rather than gradual changes as proposed by Darwin's theory of natural selection.
In summary, the correct statement is (3) only a, c and d. Natural selection is based on factual observations, Lamarck's theory of acquired characteristics is incorrect, the essence of Darwinian theory is natural selection, and Hugo de Vries believed in single-step large mutations.
