Why is sexual reproduction important for advanced animals? |
[Edit] |
Answer
Sexual reproduction produces offspring that have a combination of the genetic material of their parents. A variation or mutation in genetic code may be beneficial or detrimental to the animal, which will lead in its earlier death, OR survival to reproduce. Reproduction primarily by animals with beneficial mutations produces a purified genepool enabling the species to survive hard times through preference added by natural selection. Natural selection always prefers healthy genes to pass on and discard the weaker genes. This sort of a feat could only be acheived by sexual reproduction; it is not possible in asexual reproduction where the genetic code is same for the offspring as the parent unless drastic change due to sudden mutation occurs to produce altogether new species which is not normal.
Co-operative procreation increases the effective evolution of a creature by a factor of 6.
