  4. "Darwin's greatest failing was thinking the environment shaped organisms" - No, such insight is remarkable and bang on! Environments heavily influence the path evolution takes, via natural selection, to say nothing of the internal environments within the organism itself. Here, epigenetics directly allows the environment to decide what traits and physical shape an organism may take! "Math is more powerful than the best ever genetic modification in an established population. Why? Take a population genetics course. Species only change much through bottleneck/island effect- arguably random" - simply wrong; common or garden evolution by ns is the most common process for allele change in populations. Foster's rule (island effect) and genetic bottlenecks are just subset conditions influencing the paths evolution may take! - Foster's rule (island effect) is where geographical constraints of the environment influence the traits of the populations subjected to it, primarily by physical size - genetic bottlenecks, rather than effecting much change as you claim, often have the opposite effect; a slowing of genetic diversity. This is due to a greatly reduced population numerical size which reduces the collective gene pool diversity upon which evolution can work! In some cases this lack of diversity can lead to extinction as low gene variation leaves populations vulnerable as the ability to adapt is significantly hampered "Survival of the "fittest" often boils down to those that weren't outright destroyed by some unusual occurrence and arouse by chance, not structure." - more nonsense. - survival of the fittest, in modern usage, refers to those with better reproductive success; producing more offspring. 'Unusual occurrences' are, by definition of the first word, unusual! So, 'outright destruction' by 'unusual occurences' isn't an 'often' event! - nor do populations arise, thrive and pass on genetic success by 'chance', that's where natural selection comes into play; the non-random, non-chance selective process acting upon populations. - and 'structure', as you state, but more generally and accurately, the phenotype is what arises from ns, not 'chance', as you claim ----------------- You've amply shown your ignorance, a lack of knowledge of evolution. For those reading his comment; I urge you to disregard it as flawed throughout.
