I was thinking about the idea that we originated from a basal group of animals and plants. I saw a program that traced the DNA from a sea sponge, showing it to be an ancestor to a large diversity of life including us.
My question is, sea sponges are rather complex life forms, so where do we look for cells or molecules, which are evolving from the first processes? Water seems to be where life originates, so does new life appear continuously? I think if we look around we may see the first formations of life.
After reading some threads, some people think life may have come to Earth from space, which is something I don’t want to go into here. Our planet for starters has all the right conditions for life to start.
