Re: Explore Strange New Worlds.
Also, from a physiological perspective, it's reasonable to conclude that at least some of that life will resemble humans. As with most life on earth, our sensory organs are located in close proximity to "controlling" organ, the brain. Also, to interact with its environment, an organism needs at minimum of 2 appendages for mobility and 2 appendages for object manipulation. Of course, an organism can have 4 legs or 4 arms or more. But, 2 of each is an optimal number for efficient function. So while "life" on other planets will be strange, wonderful and terrifying, I also have no doubt that some of it will have many characteristics as humans.
Don't forget there is an intelligent organism with 4 ambulatory appendages and a single manipulation appendage. On the opposite end, there is another intelligent organism with 8 appendages that double for both ambulatory and manipulation. Not only that, 2/3 of the organism's neurons are found in the nerve cords of its appendages. If it weren't for this organism's rather insane breeding habits, well.. one never knows.. It might be able to take over. ;)
That said, there is no reason to assume that other organisms will even have fingers, much less be humanoid in appearance.
One never knows, they may have gone extinct hundreds of millions of years ago. The dinosaurs did, after all, and they were around a LOT longer than us. Billions of civilizations across the galaxy could have risen and fallen to extinction in that time. Alternatively, there could be planets with "dinosaurs" that never went extinct. Still roaming around, failing at the whole "brain" thing in favour of eating each other to death. :3
