What is needed is a better understanding of how science works. This is just more bullshit from our resident hack. 9or one of our resident hacks)
Exactly how do you propose we determine whether an animal is extinct or not?
One of the examples used was the Okapi. No sightings from 1959 until 2005. Are you saying that we should look for 46 years, find nothing, and still reserve judgement on whether any are still around?
Biologists don't have some great index of where all the animals hide. Believe it or not, they don't count Okapi on the african census. (or at least they didn't return their forms)
Is it exact? Hell no. And no scientist worth his salt will tell you that it is.
But one point to remember, if a species reaches a certain low level population, they are extinct for all practical purposes in the wild. i'm sure you will say that if one exists its not extinct, but from an environmental standpoint, thats not point.
