Consider the claw. Frequently found on animals around the world, its one of natures most versatile tools. Bears use claws for digging as well as defense. An eagles needle-like talons can pierce the skulls of their prey. Even the ancestors of primates used to wield these impressive appendages, until their claws evolved into nails. So what caused this adaptation? Matthew Borths investigates. Lesson by Matthew Borths, directed by Augenblick Studios

I really admire TED-Ed's work but I really don't like the idea of calling primate animals our ancestors. I know the evidence we have fits with the best theory we have in hand. But again it's just a theory. When you continually repeat the word ancestors, it is limiting people's perception of thinking and eventually, they will start to accept it as truth rather than thinking otherwise. Rather mitochondrial Eve and Y-chromosomal Adam is a fact that we all should understand.

I've always had white healthy nail tips, and toe tips. So much so, a co-worker once pointed out I was wearing French tips. I wasn't. It's just natural. And an ex once nibbled on my fingernail because he thought I was wearing acrylic nails. Weird. Again, I wasn't. Are white tipped fingernails that uncommon? (And no, I'm not a health nut)

U have nails, claws, and some shiny adamtium coated things at least a 1 foot long protruding out of the skin with the Wolverine.
