Yes, all invertebrates, including butterflies, are able to re-grow limbs and repair any non-fatal damage done to them.

YOUTUBE FLAW! Perhaps a video you're watching erroneously pauses half way into the video. If you hit the refresh button, the video starts not where you left off, but rather from the beginning.
Thumbs up if you agree!!!

Khan Academy now has significant backing from the Bill Gates Foundation and Google.Yet every day I search on Wikipedia, I see a large banner asking for donations or else they threaten us with advertisements. If Bill Gates funds Sal and Sal uses Wikipedia, wouldn't it make sense for Gates to fund Wikipedia? Wikipedia: "If everyone reading this donated $5, we would only have to fundraise for one day a year." Bill has the $ so that wiki stops bombarding the middle class.
Thumbs up if you agree!!

This explanation seemed like it was only half the picture (probably because mutation was only very briefly mentioned). I'd be much more interested in a video demonstrating the rate at which a mutation for pigment change (not just lack of pigment) would occur, the genetics of that mutation, and the genetics for a mutation allowing for disparate pigmentation, allowing the formation of patterns; once those are in place I see no reason why it should take exceptionally long to any pattern to appear.

lol WIKIPEDIA :D

I wonder if future evolution of species could be predicted by mathematical means
