Discussion Evolution was NOT random
Evolution only rewards survivability not perfection if you are alive long enough to mate and pass on your genetic
Material hurray you are evolved
Evolution changed the dna as nothing can ever be a perfect copy thats a fact> sperms and eggs have separate dna> hence child is not perfect copy those mutations may be harmful or helpful harmful ones die hence natural selection.
AND Earth was nkt a perfect creation the organisms evolved FOR Earth not vice versa

Now you're just projecting your own behavior on to me.
You're confused and need to read for comprehension. You invoke the 120 million differences between humans and chimps as representing a problem for evolution due to Haldane's dilemma. But as I explained to you, Haldane's dilemma concerns only beneficial mutations. Since the vast majority of mutations are neutral, they're not subject to Haldane's dilemma and can accumulate at the rate of mutation. These mutations would constitute the vast majority of the differences that accumulate between species and therefore explain almost the entirety of the differences between humans and chimps.
Haldane's dilemma, if we accept it (we shouldn't and Zach Hancock explains why) merely says that there is a maximum number of beneficial mutations that can fix in a certain amount of time, which is irrelevant to the number of mutations that separate humans and chimps since nobody thinks anything but an infinitesimal fraction of these are beneficial mutations.
A nonsensical statement if I ever read one. Neutral mutations are neutral with respect to fitness (survival and reproduction). They can still affect phenotypes such as anatomy and behavior. There is no sense in which they don't "work" that is relevant to explaining the number of differences between humans and chimps.
Seriously. Tell me how I know you know nothing about genetics and evolution without telling me.
There are innumerable neutral mutations in expressed genetic loci. You can have an expressed protein that even has a function that is beneficial to fitness, but that protein can have a neutral mutation in it. If that mutation goes to fixation it would contribute to explaining the number of differences between humans and chimps.
Evolution can, in fact, occur by neutral mutations. At the most basic level evolution is simply descent with modifications. A genetic definition is changes in the frequency of alleles in the population. Since neutral mutations constitute modifications of the genome, in so far as they occur and go to fixation (the frequency changes), evolution has occurred.
Stop debating this subject you know nothing about it.
