I'm saying that there isn't a significant reason to devide micro and macro. We can see micro and interact with it. There is no reason to assume that macro is different.
Infact there is no difference at all between micro and macro... its all just evolution.
Its like trying to make a difference between what causes gravity on Earth and on the Moon.
Now, I'm certainly no science guru (I'm a wannabe... ) but the red jumped out at me. I always thought macro evolution was far more complex and had much less emperical data we can test today. With fossils being the best we got.
Why would we assume it's the same? I can't help but see a naturalist philosophy being applied here and hopefully there is more then what I am seeing.
I dont really see a fundamental difference either. It seems its just looking at things on a different scale and in context of a larger timeframe.
I actually dislike words like macro/micro-evolution for their tendency to become such easy buzz words.
God knows we enjoy labelling and categorising things as humans, but i often think we have biases that have a profound effect on how we see our categories, and what extent differences we feel are large actually affect or relate to the said categories and how/why they were initially devised.
(Whilst keeping quite abstract still, such and example might be 3 sets of creatures, all separated by the fact they dont interbreed. 2 might look quite similar to some1, and the other very different. But on closer study of their genetics it might be revealed that one of the similar looking groups is in fact much more closely related to the odd one out than the other. This sort of error for me might highlight how someone can mistakenly get hung up on groups and identities without relating it well to the underlying mechanisms and genetics.)
For me i think its quite wonderful to see the way genetic similarities can be matched up over the tree of life, illuminating which species are more closely related, sharing a more recent common ancestor.
Without reiterating the mechanism of evolution and natural selection, i see no reason why said mechanism wouldnt produce the diversities we see today.
In a way my sensibilities tell me that it might make sense for creatures to distil into quite separate groups. Once a certain degree of differentiation has occurred, (say due to a geographic separation for example) it might be that further changes would benefit each group differently based on their already underlying differences, propelling the differentiation. (eg stronger talon grip might be now more beneficial to one group than the other, with another trait being more useful to the other group. As these changes increase, what might benefit one group will become more distinct from the other.)
