can detect a threatening chemical gradient and retreat from it.
Just where and how life began on earth is uncertain -- deep sea vents, tide pools, and hot springs all provide rational explanations -- but water was certainly involved, and as single-cell organisms
gave way to more complex forms of life, seabirds occupy an intriguing rung on the evolutionary ladder because they've happily settled at the nexus between two worlds -- land and sea.

Much of the last 30 years of research has focused on how cooperation came to be, since it's found in many forms of life, from single-cell organisms
True, slime molds are masses of single-cell organisms
without a brain or eyes, but they demonstrate amazing abilities to engage in organized behaviors, carry out coordinated movements and especially, to find their way through mazes and over obstacles to locate food sources.
