Wiki World: mutation

The reason why people feel that they were born in the wrong body in regard to being male or female is motivational. It can be genetic or cultural in nature. It is complicated. Like homosexuality there could be social reasons why this path is chosen. It could be enculturation as a child. On the other hand, individuals just have the feeling that behaving in such a way is natural for them.

Scientists have found that some people have an identification problem due to a genetic "condition". It is unfortunate that it has been called a disorder. An emotive argument is not needed. It has been given a name: craniosynostosis. The FGFR2 gene is mutated and causes sex reversal in the XY chromosomes.

About two per cent of the general population is born with a gender issue. This can have physical consequences such as endocrine complications, infertility or gonadal cancer. A baby born this way faces multiple surgeries. It should be noted, however, that people with a genetic cause for intersexuality number only 30 per cent of total "sufferers". Having an individual register with community-based support bodies is claimed to be beneficial, but this is unproven.

GENE MUTATION CAUSES SEXUAL IDENTITY PROBLEMS

Luck plays a large part in evolution. Climate suddenly changes and if by chance a species of animal carries suitable genes to flourish in the new environment that animal lives on. Other species die off because they cannot cope.

New findings about the great white shark highlights this. Australian great whites and the Mediterranean type have genes that point to common ancestry. It is believed that a few related female sharks split up. Some going north to the Mediterranean from the larger gene pool in the south, or they peeled off from the main group in the Atlantic some going north the others going south. Narrow channels in the Mediterranean stopped this group from rejoining the Australian gene pool.

This happened 450,000 years ago. Mutations since that time make the timeline clear. It is believed that swordfish and tuna the main food of the great white also split off from the their main groups. Great white sharks followed the food supply.
