Darwin's Theory of Evolution: Correct Statements
To understand why option 'B' is the correct answer, let's analyze each statement regarding Darwin's theory of evolution.
1. Evolution by natural selection started with cellular life forms.
- This statement is somewhat misleading. While natural selection is a key mechanism of evolution, it is not exclusively tied to the earliest life forms. Darwin's theory primarily addresses the evolution of species from common ancestors, which encompasses cellular life but is not limited to it.
2. The rate of appearance of new species is faster in organisms with longer life spans.
- This statement is incorrect. Generally, shorter-lived organisms tend to evolve more rapidly due to faster reproduction rates, allowing for more generations in a given time frame, which accelerates the process of natural selection.
3. Fitness is determined by inherited characteristics and is the result of the ability to adapt and be selected by nature.
- This statement is correct. In Darwinian terms, "fitness" refers to an organism's ability to survive and reproduce in its environment, influenced by its inherited traits.
4. Lamarck's theory involved the use and disuse of organs.
- This statement is correct. Jean-Baptiste Lamarck proposed that organisms could pass on traits acquired during their lifetime, such as the elongation of a giraffe’s neck due to stretching to reach higher leaves.
Conclusion:
- Therefore, statements 3 and 4 are accurate, while 1 and 2 have inaccuracies. Thus, the correct combination is option 'B', which includes statements 1, 3, and 4.
