Interesting article @samminator,
The conclusion of your post that we are related to every living organism was briefly expantiated in of my posts, we are not only related to living but share a lot with non living substances.
I'd be glad if you check it out.
To my question, do you think there is a possibility to have further evolution of animals, especially of our species where we could be having maybe people with purple skin and tall as the sky(the bible recorded very tall giants once existed)?
Well, nothing is impossible. Also remember that the process of evolution can be altered and influenced by some other non-natural factors.
Thanks for the comment
