Once an ID supporter told me that i should use "common sense", and also liked to recall that science is, in the first place, observation of nature.
I agree and when i look at an ape and then at myself, at a bat and then all gliding animals, a picture of a tasmanian "tiger" and then all hopping marsupials, a turtle and then a snake, i mean, i feel i'm using common sense. It's not a true scientific way of watching the animal kingdom, but i can't help myself, i always find wonderful coincidences everywhere.
From this point of view, i can't understand why "macroevolution" scares some people so much. The concept of evolution is simply beautiful.
