The cerebrum is part of the brain that controls the functions of the voluntary activity in the body. If an organism is smaller than another organism, for this case a frog and a rabbit.

If the half life is 5800 years, and there was only 1/4 of the Carbon 14 left in the wood remains, then 1/2 of the 1/2 life or 1/4 is 2900 years so the total age of the wood should be 5800 + 2900 = 8700 years old. We found some ancient highly compressed and water logged wood branches in an old glacial lake in the Highland Valley of BC., Canada and the lake deposits were up to 40,000 yrs old or just past the limit of Carbon 14 dating.
