Turns Human Body Modern Evolution Has Traces Ancestor

London - There are a number of parts of the body that seem, on second thought, there is no point for us. However, after looking far into the past in the process of evolution, then we can imagine.

Quoted by the Daily Mail in a video produced by Vox discuss a number of 'heritage' in some parts of our body that is touted as evidence for human evolution.

One of the most interesting are the muscles in the hands, known as palamaris longus. Apparently, the muscle is no longer at about 10-15% of the human population.

Palamaris longus muscle is the legacy of human ancestors still use your hands to climb. Its existence became supporters of the theory of evolution.

However, as explained in the Vox video production, lack of muscle does not render a person becomes weaker. Someone who does not have the muscle can still clasped as tightly to those who still have it.

Muscular shape is also different for each person. Can a tendon arrangement above and below the muscle, or a muscle in the middle flanked by two tendons on the top and bottom, or in chunks of muscle tendon in the middle. It could also simply shaped tangle of tendons. It is also closer to the wrist.

In a 2014 study which has been published in BioMed Research International, the researchers revealed how the muscle is longer in primates such as lemurs are more often using their arms for climbing.

Muscles that are shorter or even disappear in humans and apes are no longer using their arms to climb so often.

Elsewhere, the plantaris muscle located at the foot used by animals for grasping and fiddling with objects using their feet. This is why a number of apes seem to be able to use your legs and arms.

Humans also have this plantaris muscle, but not very developed and are often taken by a physician as requiring reconstruction of body tissue to other parts of the human body.

Hair that Goosebumps and Bone Tail

Another relic that we have inherited from the ancestors is bristling hair. When we kedingingan, smooth muscles that

hold the body of fine hair roots to contract so that its tip like upright.

It was useful for the furry mammals or birds, because it creates additional space for insulation and make them warmer.

Its use in human ancestors was to raise hairs on the body so it looks bigger to scare off predators.

Hair that creeps explain what we feel, as measured by a number of researchers in 2014. At that time, the Korean researchers use a sensor that can read the patch small changes in goose feathers, a process known as scientific as piloerection.

According to the researchers, the changes that occur may reflect the mood of a person that can be used to determine the number of such experiences for music, international advertising, or even at room temperature.

Tail bone (coccyx) is the very bottom of the spine humans and apes. Also there are a number of other mammals, such as horses. This is the aftermath bone relic of our ancestors.

Over time, we no longer need the tail although we still need the coccyx. The bone was now serves as the support structure for some muscle and became the backbone when someone sits or rests.

Human fetus still has a small tail up to the age of 4 weeks, but then the cells in the tail was programmed to stop growing. After 4 weeks, the human fetus so similar to other mammals fetus at the same stage.

Human evolution negates the tail when the fourth week of pregnancy, although sometimes they carry into the tail of birth as 'soft'. (Source quora.com)

In most other animals, the tail was growing. But the cells that die in humans and apes. Approximately at 6 to 12 weeks, the white blood cells to squash tail and the fetus develops into regular baby without a tail.

Most so. But, although rare, there are some children who are born with a tail that 'soft' and contains no bone, only contains blood vessels, muscles and nerves.

Ear is also one part of the body that explains the history of our evolution. There are three muscles that attach to the outer ear but not a lot of the motion, one could even say can not move.
