And the imperfections of animals that resort to eating their young, fight each other, and the imperfections that led to certain species becoming extinct...
What I meant was that Humans are the first species to "break" the system. How to put this...
Imagine you're playing Counter Strike and out of nowhere, you can shoot through walls. You own the game, and will always win (granted you aren't banned or your opponents rage-quit), as such is with humans. Rapid self-adaptation coupled with immense thinking capacity has created the most powerful life-form to ever walk Earth, regardless of size.
Evolution states that the world goes through checks and balances, and competitions for niches in the natural world will occur.
imperfections of animals that resort to eating their young
If an animal cannot support its young (Gerbils are an excellent example), it makes sense the mother eat its young to regain strength and protein to live on to make babies that will actually live and carry on the species, passing on successful genes and furthering the process of evolution.
fight each other
Animals will always fight. It has always been. Some animals eat plants, and some animals have evolved to eat teh plant eaters, so the numbers don't explode and destroy the plant life due to over-eating, causing an ecological disaster. In response, prey animals develop defenses, and carnivores will develop new methods to negate the new defenses, in an infinite loop. This creates animals like the flamingo with acid-resistant legs, allowing them to hatch in soda lakes, water too acidic for baboons to enter and feed on the flamingos.
imperfections that led to certain species becoming extinct
It's cold, hard, truth, but it's truth, nonetheless. Certain animals just can't compete with others who adapted. It's all for the better, creating better-adapted animals for the environment, strengthening their own hold in the niche they occupy.
Evolution and competition is a game. It was, until the system broke and created humans. I will continue to state that we're a mistake, we're a species that came out of nowhere, a species that was quick to dominate simply because someone found out that spears hurt more than teeth, and another discovered agriculture.
ah well. Best let the natural course work. I've said this before and I've said it again. To the stars for humanity!
