Hi, this is thrilling! Your evol. video had an antiquate, relatively uninteresting perspective on evolution. (I'm happy to know it was not written by you!). Some starting points from which I hope you can find lots of: * Evolution does not only affect physical characteristics but, most interestingly, creates well optimized and balanced behavioural strategies that maximize the competitiveness of the gene: in risk management, planning of any kind, reproduction (example). There are tons of well-reported, startlingly clever, strategies in the animal world (how bees work for example).
Evolution is about the changing portions of genes within a gene pool of a species.
the ways in which a character manages to propagate itself go much beyond reproduction. example: this helps the propagation of that gene. The less chances an organism has for direct reproduction - age, other impairments - the more it should be inclined to altruism by means of effective favours to similars, as this is the most effective way in which it can invest energy/time/risks to help the success of its genes. ofc this is all non-conscious and determined by the genes themselves.")
Evolution is a non conscious competition of genes against both other genes and the outer world. A gene that is extremely proficient in making an animal survive in the world might be blown away by a gene that is just extremely good in propagating itself in more clever ways. There are examples of noxious recessive genes, that caused sure death in hosts with "recessive-recessive" genotype, that "cheated" their way into a population because they affected the way in which genes were selected during the formation of gametes:
I'm a future physicist with a long-time interest in evolutionary theory and its mathematics.
