For all you non evolutionists out there notice that the Ph of sea water is just about the Ph of blood. When we craweled out of the oceans, we took the sea water with us. IMHO
Sorry, I meant pH but I typed Ph.
The average PH of seawater is 8.0 (it varies quite a lot).
The PH of human blood is very exact and it needs to remain 7.35–7.45
What was your point again?
