Explanation:

1. Charles Darwin's theory of evolution by natural - selection is the most widely accepted theory of evolution today.
2. The theory of evolution states that fit individuals survive to pass on their genes through the process of natural selection.
3. Fossils, anatomical and chemical analysis, and geographical distribution of species are all evidence for evolution.
4. Sexual reproduction alone does not lead to the evolution of a species. Mutation, natural selection, and gene - flow contribute to evolution.
5. Variations in the gene pool, adaptations of a species, and modification of a species over time are all key elements of evolution.

Answer:

1. b) Darwin
2. d) Fit individuals survive to pass on their genes.
3. d) All the above
4. a) Sexual reproduction
