It's a little complex in reality with men being able to reproduce for pretty much their whole adult lives (raising children that support the tribe, allowing elders to live longer and then reproduce with younger women)
Cell starts as a four legged larva before growing wings, horns, a stinger, the ability to stand upright
The dbz wiki describes the larval form as "a large four-legged cicada", and the imperfect form with "he has sprouted wings similar to those of a beetle"
That's almost true. I said natural selection only impacts odds of reproduction but there's a few things that occur after reproduction age in a population that have been studied to be naturally selected tooo
Behaviours of gays and the elderly are selected for to an extent because they help raise children in the tribe/community/group whilst not affecting reproductive pressures
Improving survival odds through nurturing children/others leads to groups with those genes doing better, which selects for those genes via natural selection
If the older members of the group are fitter and can help gather food/hunt then those genes are selected for too through increased survival of their offspring
