Speculative Zoology

=== What is Speculative Biology? ===
Speculative biology is the act of speculating how, why, where, and when life forms would change or form. This can be a full biosphere, or simply a change in a single species over time. For example, on earth, we have large tusked elephants and those with slightly smaller tusked elephants. Recently scientists have been seeing an overall decrease the size of tusks of elephants due to hunters killing those with/with larger tusks. Thus, many people have pondered a future where tuskless elephants are the norm.
=== Lunar Biology: ===
Lunar life, like Terran life, had access to a very similar intensity of given light wave length. It may than come naturally to presume lunar life would be, as Terran life, green, however, this isn't correct. The only reason the bi-chlorophyll system developed on earth is because red and purple life stopped most of the light-waves they absorbed from reaching plants. Later when plants developed large multicellular life the retained the extremely inefficient green pigments. This is also why in recent years scientists have tried developing more efficient plants with a completely different and red pigment. On the moon, while the same factor would be in place at some point, the dice were cast and did not develop green pigments.
