of physical prowess. For most creatures (look at plants), intelligence and tool use are not at all necessary. In fact, to most ecologists and evolutionary biologists, intelligence can be seen as a liability in most species. Why waste resources (food, blood, calories and bone protection) on a giant brain when your legs, hooves and teeth do the job just fine? If you're a rock stupid water buffalo on the African Savannah, will it really get you any more fine buffalo chicas if you can craft a wicker basket from papyrus? Oh, you could try, but I'm pretty sure your enormous efforts would be rewarded by the female buffalo with a monumental disinterest and a glazed over look of epic stupidity in her eyes.
thout encountering dozens of such examples. No, the second reason this article caught my eye is the most important one, and prompted this post: evolution is not always an improvement. Popular interpretation of the theory has seemed to put forward the idea that evolution is always moving forward. Evolution Adidas Gazelle Grey
is always an advancement. What people forget or never learned about is that the bare bones theory of evolution (natural selection causes changes in organisms gradually over time) makes no assertions whatsoever that the changes will be for the better. The engine of evolution (genetic Adidas Gazelle Dark Indigo Blue mutation and variation) is NOT, as ID proponents might like to make it, a directed force. It is random. As is natural selection. The selecting force in an ecosystem is ALWAYS an environmental factor. But it should be remembered that, like the case of the Atlantic silverside, natural selection can, at times, overwhelm a species. Over 90% of all the species that have ever lived on the planet are dead. Gone.
And if he does so, evolution will reward him with a large harem of the finest females around. It's good to be the king. Laziness is rewarded in the natural world (when possible). The simplest, no frills designs are usually the best. Anything flamboyant or extraordinary you see is most likely the result of high enviromental pressure. Look at plants and microbes. Unchanged for billions of years except minor variations. And they just sit there. Humans are predators. Make no mistake about it, my friends. But without the brains and tool use to compensate for our embarrassing lack of indigenous weaponry, we are as the 'Far Side' once described us in the guise of two anthropomorphic crocodiles lounging on the side of a river: "That was incredible! No teeth, no claws, no fur, no nuthin! J.
Extinct. Natural selection can be like Mother Nature's bitchy sister. Remember evolution's simplicity: Those organisms that have the genetic makeup which allows them to produce more offspring than their counterparts will thrive. This does not always mean advancement. Their offspring may be deformed or otherwise inviable, but there are more of them, and that means they win. Another common misconception is that what is advantageous for homo sapiens is advantageous for everyone. Flat out wrong. High intelligence and tool use are advantageous to us because of our lack Adidas Originals Gazelle Indoor Trainers Blue
