bruh, shit that serves a benefit stays, the rest gets lost.

Yeah sure

How does the slow speed benefit sloths?

they make up for it with other developments?

What about tenancy to put on fat at the hips

Australopiths diverged into two subspecies. fossil evidence strongly suggests that a large amount of cannibalism occurred.

Or sickle cell disease

mutations?

What about blue eyes

that's a mutation...

That have any benefits

Oh I see

in fact that's also a weak gene. gets bred out easily.

sickle cell trait is better than dying of malaria, if it comes down to it...

So you say only beneficial things stay but all the none beneficial things are mutations

Super convenient

Blue eyes help men determine paternity

it used to.

everything is a mutation, the beneficial mutations stay.

Blue eyes is a weakness in eye sight

You have no proof

But paternal investment is a strength

Bonbos are weak

i think you're going full retard.

@unholybob I'm talking to haku

In truth again evolution is random that means you get good with the bad

random yes, but only the features that serve benefits pass on.

Sickle cell also drastically lowers quality of life because your hemoglobin is deficient

it's dependent on the current living conditions.

Oh now it's dependant

it's always been dependent...

what in the actual fuck

dude come on....

So essentially you have created a mental structure in which you can never be wrong. You can explain away all contrary evidence as temporary and all non temporary as a throw back to other times

evolution is only random insofar as mutations occur at a random interval... the selection for or against those mutations is not random. A mutation that kills an organism has a strong negative selection pressure. A mutation that helps an organism has a positive selection pressure.

You're strawmanning the fuck out of everything.

Go pick up an evolution book.

And a mildly negative mutation ?

mildly negative selection

My point is strong negative pressures may get worked out, weak would not

Off the top of my head, sickle cell probably survived indirectly through other benefits.
