No matter how smart a bear became, it still wouldnÃ¢â‚¬â„¢t be able to make tools because it lacks free hands and opposable thumbs. Primates are ideal candidates for developing intelligence, because they already have dexterous hands and feet from climbing trees and eating fruit. And many primates, like chimpanzees, live in groups of up to 50 individuals. Social interaction and brain development go hand in hand.
"Bears are well adapted to their environments, and a slight increase in intelligence wouldnÃ¢â‚¬â„¢t be enough to cause any significant change."
If this is the case then how did humans "evolve" higher intelligence, since evolution is a slow process, with "slight" changes over time..
When you look at our society today, it certainly seems like weÃ¢â‚¬â„¢re far more superior. But in a hunter-gatherer society with a simple language and basic tools, the intelligence gap isnÃ¢â‚¬â„¢t quite as wide. In fact, the neurological differences between humans and apes are actually quite subtle... or at least they would be, if we had retained our primitive lifestyles. But humans began to live in groups, hunt rather than scavenge, and travel long distances in search of food. By doing so, we were exposed to different selective pressures than other animals. With the later development of agriculture, people were able to stay in one place and form communities, towns and eventually cities. As our culture grew increasingly complex, so did our ability to plan and invent.
Also if humans are able to "evolve" intelligence then why not animals by the same evolutionary mechanism. Why in the whole world are we FAR more superior in intelligence to any other organism on Earth.. Perhaps it is asthe Bible says that God set Man apart from the animals
