A human brain (average size 1,300 grams) versus a dolphin brain (1,600 g). However
"The human brain has a far more developed hippocampus than the dolphin brain. The hippocampus is a somewhat small region in the human brain that is shaped like a seahorse. The hippocampus is responsible for the elements of memory, learning, motivation, emotion, and more."
Apparently it's too late for dolphins to ever transition back to land again. They're probably safer there anyway. Besides it looks much cooler, with significantly less waiting in line.
Underdeveloped hippocampus or otherwise, they sure seem to be enjoying themselves out there :)
ReplyDeleteYeah they do. But, like dogs, they also happen to have a mouth shape that looks like smiling. In one scifi book or the other, dolphins were consulted to guide an agreement between humans and (I think) some aliens. I think it was written by a scientist who worked on the Manhattan Project at Los Alamos.
