humans…
"We humans tend to have a rather exalted opinion of ourselves, and that attitude can color our perception of the biological world. In particular, our attitude about what is higher and lower in biology, what is advanced organism and what is a primitive organism, starts with the presumption that the pinnacle of nature is ourselves… Nonetheless, other organisms, if they could talk, could argue strongly for their own superiority. This includes bacteria, which we often think of as the rudest forms of life"
(Darwin’s Black Box, 1996)
