We know that brains are big because we some people donate their brains to science so that we can look at them and find out what we can about brains! Brains are getting slightly bigger over time and certain parts of the brain are looking more developed This is a great article that briefly explains how we know our brain is bigger now then it was a million years ago what parts of the brain are changing shape! https://www.scientificamerican.com/article/how-has-human-brain-evolved/
