placement of our body parts

@TLK

I understand that part, although in terms of eyes and ears, that more if a defense mechanism. Depth of vision and surround sound (possible by two ears) are needed to tell us which direction and how far the predator is…

… but then why the redundancy was but given to heart?

heart, brain etc are pretty well-protected in the thorax/cranium, poking at them isnt easy. chances of damage from accidents is relatively lower as opposed to damage to organs like skin, limb bones. therefore lower repair, maintenance, regeneration. also, cost of maintaining a second heart or brain? dat stuff be espensive. brain eats like 10% of our energy cost.
