By the cavity size inside the skull based off a human skull cavity size today.
Different material wears down the teeth at different rates. So depending on where the body was found and what plant matter grew there or animals grazed there would determine the food sources.
the type of hominid who could grow as tall as modern humans
Yes, scientists can use carbon dating to determine the age of hominid fossils. Carbon dating relies on measuring the amount of carbon-14 present in a sample to estimate its age. However, carbon dating is typically used on organic materials up to around 50,000 years old, so other dating methods may be necessary for older hominid fossils.
Some people think Bigfoot represents a type of hominid that could be classified as a 'caveman.'
That evidence is homologous. Shared common ancestry. In this case you could trace this homology back as far as the common ancestor of gorillas and hominid fossils, or as far back as the emergence of all tetrapods.
You could estimate is as 0.5
A cat is an animal.
From the life nutrition for the brain store.
They do not have anything that could be called a brain.
Yes, a brain freeze could actually kill you.
It could estimate to 480 or even 500, depending on what way you want to estimate it to.
Brain cells, mainly neurons, are what make you and make how you work. Without brain cells you could not exist.
Yes and no. The brain human brain could cope with it but we currently have no way of synthesising an eye or the optic nerve and its connection to the brain.
