Forensic facial reconstruction accurate reconstruction possible is largely limited. A second problem is the lack of a methodological standardization in approximating facial features. A single, official method for reconstructing the face has yet to be recognized. This also presents major setback in facial approximation because facial features like the eyes and nose and individuating characteristics like hairstyle - the features most likely to be recalled by witnesses - lack a standard way of being reconstructed. Recent research on computer-assisted methods, which take advantage of digital image processing, pattern recognition, promises to overcome current limitations in facial reconstruction and linkage. Reconstructions only reveal the
Human skeletal changes due to bipedalism result, in humans the muscles of the forehead (the occipitofrontalis) are only used for facial expressions. Increasing brain size has also been significant in human evolution. It began to increase around 2.4 million years ago but modern levels of brain size were not attained until after 500,000 years ago. Zoological analyses have shown that the size of human brains is significantly larger than what you would expect for our size. The human brain is in fact three to four times larger than its closest relative - the chimpanzee. Even with much modification, some features of the human skeleton remain poorly
