Question

why complex organism are dependents on sexual mode of reproduction​

Answer 1

Answer:

Many organisms – including microbes, plants, and some reptiles – do reproduce asexually. But the vast majority of living things reproduce sexually. ... Sexual reproduction allows for greater genetic innovation over time than clonal, improving the chances that an organism can solve the problems at hand. Sexual reproduction provides a constant supply of unique organisms. This is particularly beneficial in a rapidly changing environment because it increases the likelihood that at least some of the individuals will possess an adaptation that would allow them to survive in the new environmental conditions.
