the easier it is to control tongue movements‚ which is utilized for different speech patterns. 4. The reason why speech abilities were unable to be determined through the finding of brain fossils is because the space in between the brain and the skull was too much. The findings in mammals would yield a “fuzzy” result. Also‚ speech is not controlled by one section of the brain‚ it is found all spread out within the brain‚ making research especially difficult. With these problems at hand‚ researchers

newborn’s skull‚ there are a few features that are quite different from an adult in order for proper growth and maturation to occur. The baby has five separate bone plates in the skull. These plates will fuse together by the current fibrous sutures connecting them. In a healthy infant‚ the sutures should remain flexible for adequate brain growth until around 25 months. These sutures‚ and fontanels‚ are necessary for the birthing process. Fontanels are what gives babies the “soft spot” on their skull. When
