Another example of luck or chance in evolution???
Add story link to stumble upon
Yesterday i mentioned about a paper by Brusatt et.al describing the role luck or chance might have played in survival and dominating of Dinosaurs in Jurassic era. Cindy @ Bug safari writes about how she helped a Giant Swallowtail to regain its flying ability ,which she lost after damaging a part of wing. AYDIN @ Snailstail mention an important point about our interference with natural selection ,but here I think comes the factor of luck,chance or accident in evolution. It was the luck of the insect that she found a kind hearted person in Cindy and which has provided it with some more years of life to enjoy the beauty of nature.
Sentimentality does not exist in nature.– Karl von Frisch, The dancing bees, 1953
Humans cannot be and shouldn’t be as cruel as Darwin’s natural selection.We humans have heart and brain which knows the value of pain,care and affection unlike natural selection,but having said that Natural selection is ultimate truth and luck plays a minor role and also one cannot get lucky all the time.

I totally agree.
As I said on Snail’s Tales, that’s why I feed my porch spiders (my wife and I name them too).
Granted, this isn’t quite as altruistic as fixing a butterfly’s wing. But I like our spiders (even the black widows), so aren’t they just lucky they wedged themselves into the safe and bountiful niche of my porch? couple of pics.
Besides, as any good biologist or scientist should know, “natural” doesn’t really mean anything. We are a part of nature, a part of the system, and a part of the selective pressures. There is no “good” or “bad” in evolution. Hell if it weren’t for all the mass extinctions we wouldn’t exist.
Sorry - I ramble.

our ability to know pain, care, affection is due to evolution through natural selection. natural selection can develop co-operative as well as competitive instincts. i agree though that humans due to our unique cognitive abilities can override competitive instincts and cooperative on scales not seen elsewhere in the animal kingdom.
cheers
Yeah very much true suvrat…….
