How long does evolution take to occur?


Recommended Posts

I want my future offspring to be noticeably stronger and faster and physically superior to other humans. 

I know that mutations are mostly random and that can be sometimes passed down through generations

I know there is selective breeding where you can breed with people who have your desired traits and you can breed with them for a probably outcome of offspring

I know evolution occur in population not a single person

I am wondering if I tick all these boxes, how long it will take to evolve into stronger faster and physically superior human beings?

It's not 'proven' but the reason why we grow up so slowly and tend to be physically weaker then primates is probably because our brain demands a lot of energy.https://www.sciencemag.org/news/2014/08/why-do-humans-grow-so-slowly-blame-brain

So if you find a way the body grows faster then other children then that might mean the brain develops less.

That would be awesome to sacrifice a little brain power for physical power.

Can you dumb that down for a layman? What does that mean exactly in relation to my thread?

By applying coalescent theory,  we can estimate that the average number of generations required to fix a given allele in a given diploid population is 4 times the effective population size. This can be modified by a mutation rate or selection coefficient (u) to give the average rate of fixation for a given allele under a specific mutational model. 

So, if you were asking how many generation does it take for a genetic mutation that confers a certain phenotypic trait to fix in a specific human population, the answer is 4 times the effective size of the population, times the selection coefficient of the trait in question.
