There are several animals on earth that show certain kinds of intelligence. Some animals have extensions to manipulate their environment and some do not. Think of humans and squids (hand/extension side) versus whales and dolphins on the other (the no hand side). Learning how to use their hands also gives babies a boost in their development.

My question is: Does the ability to manipulate your environment affect the type of intelligence?

I'm pretty sure that it affects the, let's call it generalized intelligence, but does it also change the type from more or less aggressive?

What do you mean, 'Type' of intelligence? Are you arguing there is a correlation between the amount of limbs one has and how 'aggressive' a being is? –  Steven Jeuris May 9 '12 at 22:56
Perhaps the following would be a useful starting point for theoretically grounding your question: Wasserman, E. A. (1993) Comparative Cognition: Beginning the Second Century of the Study of Animal Intelligence. Psychological Bulletin, 113 - 211-228 PDF. –  Jeromy Anglim May 10 '12 at 1:55
@StevenJeuris yes, exaclty! –  draks ... May 10 '12 at 6:50
I'm afraid I can't help you out, but you could bump this question by editing it, taking Jeromy's comment into account. Perhaps you find the answer yourself. :) Don't forget you can also answer your own question. –  Steven Jeuris May 14 '12 at 12:31
This question is very vague. What are the different 'types' of intelligence? How is aggressiveness related to anything? Also, please try to cite some of your claims like " Learning how to use their hands also gives babies a boost in their development." A boost in the development of what? Hand use (tautology)? Or general qualities associated with intelligence but not directly related to having hands: say language use? –  Artem Kaznatcheev Jun 27 '12 at 11:16
