Biological Modifications? Diversity?

[LadyJawz]

In the world of Biology, it seems now days nothing is sacred. Just recently I read about a mouse who was created and can tweet like a bird, among other mice that these Japanese scientists created(each with its own distinct "mutation") and for nearly two minutes data was stored in a atomic nuclei, a beetle shell was discovered that refracts light that might help in Quantum computing, and then theres that arsenic loving bacteria which wasn't to amazing(to me at least)by itself but defiantly a worthy discovery.

When I think about how far the world has advanced since well as far back as I can remember this has always fascinated me, what other kinds of life forms do you think exist? Perhaps in a nearby solar system or at the edge of the universe. We already know life can be diverse, but as far as we can tell "life as we know it" may or may not exist elsewhere. Is Terra just a accident? maybe a mistake? or is there life out there? if so what kinds of modifications might similar species to the ones on planet Earth that are elsewhere have developed? How much diversity can life obtain from the very small to the very large? What would trigger certain things to happen as compared to earth somewhere else in the universe?

Is it so hard to imagine that possibly, some 3.8billion lightyears from us there may be a binary star system with a habitable planet? So what are your views on extraterrestrial life, exo planets that may be habitable, the Geography they might have or the physical effects of the 4 fundamental forces on the biological lifeforms on said planet? and how would life adapt to meet such requirements? What kind of defense mechanisms these creatures might have, Why "this" works and "that" doesn't. Please be creative with your ideas and explain why or how said traits and abilities might be/have occurred.

To start this off, I have a fairly open view of this kind of thing. Although its not beyond my imagination to think of animals that is a land animal but has chlorophyll in its skin allowing it if needed run plant chemical processes for extra needed energy, also a green pigment would help in camouflage.
