Somebody made a thread here a few weeks back about a biology book/pdf around the meaning of life.

It was basically about how all life forms are just at different stages of evolution, that every creature is just a compounded form of another etc.

As far as I remember there was around 4 authors involved.

If anyone can remember or knows what I'm talking about, an (OP) would be greatly appreciated.

I have a biology essay to write and there's some good content in that paper.
