Affiliate Marketing Secrets

I’m reading the beak of the finch and I just got done reading it. There’s a quote that says…
“Chimpanzees in the last day of the African rain forests are teaching their children how to crack nuts with stones. They are taking the kinds of halting,modest steps that might, if favored, if selected for many generations, carry them on a path toward something like our niche. Watching them, human observers notice striking variations in intelligence from individual to individual. Where there is genetic variation, there is room for selection and evolution. Probably in every line of primates there are a few, like Imo on her island, who could lead their kind in our direction. But at the moment of course that path is blocked. The thinking niche is taken, at least for the moment.”
I don’t understand what the few lines mean. If anyone knows, please tell me what it means esp the the thinking niche is taken…

Chimpanzees!

I see stupid things like “If evolution is real, then why are there still monkey? Shouldn’t they have evolved into humans by now?” Really? For those of you who don’t know, back in the day, before Darwin, people believed in “The Chain of Creation” (or something along that line) it had humans at the top and all the lower animals below, so it was basically saying that humans were the pinnacle of creation. Well that’s not how evolution works. About 5 million of years ago humans and chimpanzees diverged (think, a fork in the road). We became what we are today because for us brain power was important, chimpanzees went where they are because that worked for them. Its what’s called a “Niche” its where an organism does best (like a carpenter or a painter, they do best in those jobs, so they stay there).
Also evolution does not say that an organism has to constantly change “if it ain’t broke, don’t fix it” an organism only changes if its niche changes or is destroyed, then-hopefully for the organism-a mutation will acer that will allow it to survive, if not then it will become extinct.
Now if you want to know all the details read “On the origin of species by way of natural selection” by Charles Darwin, or another book on the mechanics of evolution.
