Having a big heart is only required when they have a big body. Giraffes for example have very large hearts, but that's because they have very long necks. They need an extra-powerful pump to be able to push the blood all the way up to their heads.Juvenissun said:I have big problem with that. Why would the brain/body ratio affect the function of the brain? Should a better brain actually be correlated with the size of heart? Bigger heart > more blood > better brain.
Whales too have very big hearts to support a very large body - they are also one of the few exceptions to the Encephalization Quotient: they have small brains compared to their huge bodies, but that's because they live in the ocean.
Having a large heart does not correlate with having a large brain, or being intelligent.
No, we can tell it cannot walk upright because it has weak knees and spine (compared to a human), its neck connects to the back of the head (rather than underneath) and its hips are long rather than bowl-shaped. It's feet too are not adapted for walking upright for long periods of time.Juvenissun said:So if we only see the skeleton of a chimp, we don't even think it can walk straight at all. Right?
Correct me if I'm wrong, but are you arguing Aridpithecus was actually a human? If so you're the first Creationist to do so.
