The smartest thing I ever heard about evolution: „It’s rolling dice and keeping the sixes.“ There is neither a goal, nor a peak. Evolution is a load of completely random mutations. The ones that help a species to survive in their specific environment are „kept“.
Also oftentimes, stuff that was kept because it makes thing possible, turns out to be useful for completly different thing
Fingers helping apes climb, but they also allowed the use of tools.
It’s worth pointing out that evolution sometimes will just randomly evolve traits that don’t really help a creature survive more, it just doesn’t make it worse at surviving.
if you have it, life is hard. pre-modern-medicine you died young. however if you are just a carrier (you have to carry two recessive genes to have the disease, but if you only have one you’re a carrier. i think it’s recessive, i learned this 20 years ago) you have remarkable resistance to malaria.

i want to point out sickle cell anemia.

life is funny that way.
I mean, DNA does have regulatory and feedback mechanisms. Some of which we don’t even understand yet.
I find “it’s always just patches” from software engineering more fitting.
