There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
Thanks for beautiful answer spalea. But technically thinking it becomes difficult for brain to get nourished with blood as heart has to pump vertically upwards. Blood has to flow against gravity. Even then man evolved intelligent. That is something like a great achievement IMO.
