Remember my mantra: distinct... or extinct.
Sentiment: NEGATIVE
Extinction is the rule. Survival is the exception.
Most evolving lineages, human or otherwise, when threatened with extinction, don't do anything special to avoid it.
Take the crocodile, for example, my favorite animal. There are 23 species. Seventeen of those species are rare or endangered. They're on the way out, no matter what anyone does or says, you know.
In the landscape of extinction, precision is next to godliness.
Biological diversity is messy. It walks, it crawls, it swims, it swoops, it buzzes. But extinction is silent, and it has no voice other than our own.
Remember that what you have is unique because it's your own special way of looking at the world.
If you think about it, every single species is endangered. Homo sapiens at the front of the line, mosquitoes and lawyers at the back.
An animal that is very abundant, before it gets extinct, it becomes rare. So you don't lose abundant animals. You always lose rare animals. Therefore, they're not perceived as a big loss.
Every single record I have is a fossil.
Species go extinct because there are historical contraints built into a given body or a given design.
