Detailed explanation-1: -Another theory is that sexual reproduction originated from selfish parasitic genetic elements that exchange genetic material (that is: copies of their own genome) for their transmission and propagation.

Detailed explanation-2: -Obligate asexual reproduction has been thought to arise because of inbreeding or mutation in large populations (Scheuerl et al. 2011). Facultative sexual reproduction is relatively rare, being only observed in a few animal species.

Detailed explanation-3: -About 1.3 billion years ago, sexual reproduction starts mixing genes and paves the way for the great diversity we see today. It’s hugely important on this timeline because it allows organisms to begin combing genes, allowing the next generation to do more than its parents; upping the chance of survival.

Detailed explanation-4: -All life, evolutionists teach, was asexual for eons. The common attempt is to state that sexual life evolved from asexual life, but sex will not work until two complex systems in the two sexes are compatible. The problem of how reproduction occurred before both systems were evolved concurrently has never been answered.

Detailed explanation-5: -We assume, anthropocentrically, that reproduction requires two individuals. But in many organisms that is not true. Life originated without sex (as best we can tell) so sexual reproduction is something that had to evolve.
