i wonder how natural is nature today. people intervene with nature to keep it natural. we replant trees to make up for the damage we did by logging. we open botanical gardens and zoological gardens to save the biodiversity of these species, while halfway across the globe people still continue to bring destruction to the habitats other organisms.
it took plants and animals millions of years to evolve to where we are today, but it seems that evolution is happening at a much faster pace these days.
what if we stop or dont stop many of the researches going on now? i wonder will one day human look like a butt head with a humongous brain (or two) on a puny body with equally tiny limbs that can barely support the gigantic head. that might be an interesting sight to see..
