"The average species on Earth lasts for only about four million years, so if you wish to be around for billions of years, you must be as fickle as the atoms that made you."
Question:
How long ago did the first true human being come into existence and what will humans look like millions of years from now if we are even around?
Comment:
I had never thought about a species as having an average life-span, though it makes sense now that I think about it. Many species have gone extinct just in my lifetime, so how many millions of species have gone extinct that we might not even know about? Also, I am curious about if human beings will be around for millions of years, or will we too be gone not long from now. If we do make it, I wonder what we will look like, how we will have changed to fit our new environment and what technology we will have in the future.
