Tool Use Among Chimpanzees Jane Goodall was the first person to ever document seeing a non-human animal create and use tools. (Atkinson) We now see that tool use among chimpanzees is not uncommon. Upon this discovery we have figured out they have many ways to use and craft tools. There is a bit of a difference between tool uses and acquisition among wild and captive Pan troglodytes. The wild chimpanzees have all types of materials to choose and work from in the wild and rely more on tool use for

correlation between left-handedness and homosexuality (Lumiere‚ 2000). This is not to say that all homosexual people are left-handed‚ but that homosexuals have a greater chance of being left-handed than heterosexuals. Another study‚ made by Hall and Kimura (2000)‚ showed that gay men have fingerprint ridge patterns that display more leftward asymmetry than the fingerprint ridge patterns of straight men. It was also found that this asymmetry co-occurred with left-handedness only in gay men. In identical

Problem: Which hand can tolerate cold better: dominant or nondominant? Background: Handedness is dominance of either your right or left hand over the other‚ which means that generally one hand is better at motor skills than the other. It involves the coordination of large muscles carrying out smooth motions‚ such as throwing a ball. These actions use many neurons‚ and require concentration. The left side of the brain controls the right hand‚and the right side of the brain controls the left hand.
