Interests: Expanding Earth

While pursuing an evolutionary biology degree at Purdue in 1990, I began thinking about life on Earth in terms of its gravitational definition. Terrestrial life certainly has it, whether or not you think of it as a constant, continuously unchanging influence since the dawning. However speculative you consider the possibility of life anywhere else, the fact remains that if the surface gravity of Earth was different here, then life wouldn't be the same.
