If evolution is real then let it strike me down where I stand!

Evolution will judge you harshly in the afterlife, heretic

Evolution has a dad unlike you.

I see I've discovered a hole in your conspiracy theory

Your argument doesn't make any sense. What you're essentially saying is "if A is good, why don't we see B, when B directly hampers A".
Evolution is largely driven through the exchange of multiple sets of genetic information, i.e. when two individuals with different genomes breed to produce offspring with a variable genome made up of a random combination of the parents' genes.
Self-replication as a process is much less effective at evolution, because the only factor driving genetic variation between generations in this instance are chance mutations.
If evolution is an important factor in determining which species continue to live, we would expect to see that the process which results in increased genetic variability (i.e. Sexual intercourse between multiple individuals) be found in more species, especially more complex ones. And we do see this.

>if a mate cannot be found

If a mate can be found in a high enough percentage of cases, then there is no evolutionary pressure to evolve hermaphrodite capability.

> much more efficient way to get offsprings.

Perhaps the existing method is efficient enough, and no additional efficiency is needed.

When it comes to evolution, necessity is the mother of invention. No necessity? Then no invention.

Sexual differentiation forces genetic variation. If there were an easy way to self-reproduce, there would be no need for sex. Need for sex helps to build social structure, although it isn't always involved or necessary. Genetic variation allows for faster evolution and adaptation to a wider environment.

Because we need genetic diversity I'm order to evolve in the first place

Because we don't need 23 chromosomed niglets running in circles with donald duck in his burning white house.

Now we have the benefit of competing. Women buy more clothing, daddy has to work harder and matchmaking is on channel 69. Television keeps kids at the house and pizza can be ordered. Pizza raises the demand of cheese and cheese secures the life of some cows.
Ergo, evolution knows best

>she

See I thought it was so viruses couldn't just infect everything in the world in one shot because the code never changes.

One hypothesis on why there are sexes is parasite protection.

So, parasites evolve much faster. Humans make a new generation every 20 years while many microbes can make a new generation every 20 minutes. Without sexes, most offspring are just clones of their parents, or at least, direct descendants from one individuals genome, and parasites can quickly evolve to target that genome specifically. With sexes, there is a lot more variance between parent and child, so parasites have more trouble adapting to the species as a whole.

There are other pros and cons. One of the cons of sexes, is that each offspring has only half of your genes, and you half to reproduce twice as much to get the same return on genetic replication. The pro is that inbreeding is much less of a problem.

>When it comes to evolution, necessity is the mother of invention. No necessity? Then no invention

This is such bull. Evolution != natural selection. Some evolutionary processes are not rational to any need. Sexual selection, for example, can be almost totally random, and detrimental to fitness.

Because most everyone who ever existed had no trouble getting laid.

can you imagine every human being capable of self-replication

you could barely call them humans
after a few hundred generations, almost everyone would look different

I know I'm late but there's a serious fucking stupidly simple answer for this question.

Evolution is gradual change via mutation achieved by passing on genes that change during meiosis. If a hermaphrodite or "futanari" (aren't those things only fictional, some sort of half-man half-woman beast?) cannot pass on its genes, it cannot experience a mutation in its offspring, and thus a trait to aid in natural selection cannot be evolved because the act of reproduction wasn't possible in the first place.

Omg what if you got pregnant every time you jerked off?

>>8944499
Clearly you'd have the capacity to bend your penis inside yourself

>>8943950


For this to happen not only would it have to be more beneficial (which it isn't for many reason), but most importantly it'd have to happen at a higher rate than people fuck.

Just because it's hard for you to get laid doesn't mean your ancestors had any problems.

>>8943950
Because our ancestors since the microbial stage had two genders to reproduce sexually.

Out faggot. Your little raid leaked a while ago, save us all the trouble of summerfags and stop wasting our time as well as your own. Your not changing the contrarian hellhole of the internet.

To you. Your theory forgoes the recombination step, which is a vital part in the mechanism of genetics.
