Hair and Fur as Evidence

Evidence is both large and small, still important for every investigation. In most cases, the evidence is so small that it can not be seen with the naked eye. Through various visualization, collection and preservation techniques hair and furry evidence debuted in the forensic scientific community and courtroom. Human hair and fur from animals are similar, but there are many different features. For example, human hair usually has color and pigmentation over the entire length of the hair shaft.

Clear evidence of the earliest hair and fur was in the fossils of Castorocauda and Megaconus in the middle of the Jurassic, 164 million years ago. In the 1950's, it is suggested that the foraminifers (channels) of the maxilla and maxilla (front of the maxilla) are evidence of channels and whiskers (ie) to provide vessels and nerves with whiskers (ie), thus hair and fur it was done. However, as modern lizard Tupinambis pores are almost the same as roots other than mammals, it was immediately pointed out that foraminifers do not necessarily indicate that animals have tentacles. However, a popular source of information is attributing beard to trinaxodon. Studies on the Faeces of the Permanent Indication that synapses other than mammals at this time already have hair that may cause hair growth than Forsythia

The fur of modern animals is connected to nerves, so fur can also be used as a sensory input transmitter. The fur may have evolved from feeling hair (beard). The signal from this sensory organ is explained in the neocortex, a part of the brain that is significantly expanded in animals such as Morganucodon and Hadrocodium. More advanced cerapsides may have a combination of bare skin, beard and shield. Complete fur may not evolve until the cerapidic - mammalian transition is complete. More advanced and compact cerapidides may have combinations of hair and shields that still exist in modern mammals such as rodents and Possum.

Tuts Plus points out that drawing the skin of animals like fur is not always the same as drawing hair of human hair. Animals with fur are thick and uneven layers of hair, but human hair tends to flow and move. Believe it or not, these things may actually be reflected in the way all lines are drawn. DragoArt shows you that skill sketching the eye is the correct shadow. Just painting a flat, angleless eye diagram without paying attention to reflections and depths makes the created person look as if there is no depth or emotion.
