What is particularly interesting about our species? For a start, we walk \_7\_ on our hind-legs at all times, which is an extremely unusual way of getting around for a mammal. There are also several unusual \_8\_ about our head, not least of which is the very large brain it contains... Our forelimbs, being freed from helping us to get about, possess a very high degree of \_9\_ skill. Part of this skill lies in the anatomical structure of the hands, but the \_10\_ element is, of course, the power of the brain...The most obvious product of our hands and brains is technology. No other animal maneuvers the world in the extensive and arbitrary way that humans do. The termites \_11\_ constructing intricately structured mounds which create their own “air-conditioned” environment inside. However, the termites cannot choose to build a cathedral instead. Humans are unique because they have the capacity to choose what they do.
