The leap of faith (being ironic here lol) and the reason I maintain that traits are never "given" to an organism, was figuring out HOW. From there? there really is no way creatures are given anything more than perhaps optimal nutrition... but how would an optimal environment cause changes? Make creatures evolve? We had undeerstanding of how to optimize and control for traits... Pea Plants! Fruit Fries... But that is different... That is the range that develops where a creature has optimal, to suboptimal conditions, how does a creature change from there? The conclusion is as ingenius as Neuton's alleged Apple... if the environment cannot "give" it certainly can take. Those traits that are counterproductive can be eliminated through natural selection. It made sense because it explains why things like moniter lizards grew so large in isolation. The bigger animals were not taken out in the absence of predators. And this also explains why animals like insects were so large in prehistoric times: It turns out that size is often a trait that is counter to survival. Bigger animals need more resources, etc.
