Punctuated Equilibrium Redux
A little bit of filler until I get back. I actually made two days ago.

I'm not actually talking about Gould's initial stance, that Phyletic Gradualism is replaced by Punctuated Equilibrium. More than anything, I disagree with the idea of "stasis." Genetic mutations will occur regardless of outside factors, and if an organism can outcompete its predecessors, it will pass its genes on, regardless of if it "needs" a trait or it "needs" to evolve. Stephen J. Gould's initial stance depended solely on natural selective pressures. Naturally, this would play a huge part in speciation, but two things to bare in mind, one of those pressures is the rest of your social group with whom you're competing, and the tendency of many organisms that choose their mates, to go after new traits that appear "beneficial" or "interesting."
Also, at one point, I use the words "the parent group does more to inhibit new traits from appearing than to promote them." If I didn't quote Aron-Ra's 11th Foundational Falsehoods of Creationism, I definitely paraphrased him, and forgot to give him credit in the video. My apologies in advance. But this has more to do with the spread of certain traits, rather than their emergence. Those traits will appear regardless of the size of a parent group, but for it to be expressed in the parent population's genome, its a difference of countless generations vs. significantly less when talking about Gradualism vs. PE. The difference is stable selective pressures that a population has grown used to over countless generations vs. harsh selective pressures that drastically cull off members of the parent populations, at which point, traits that helped an organism survive but were abnormal, have now become the norm.
