A Brief Description of the Question: 

Does earlier puberty in hot regions originate from the effect of the climate and geography on DNA?

The Answer: 

DNAs are molecules where the genetic structures of the living beings that they receive from their parents are coded. Their structure does not change so easily. Therefore, the age of puberty is directly related to the secretion of hormones.

In the individuals that reach a certain physical maturity, difference in attitudes and feelings develops in males and females based on the intensity of the sex hormones that are secreted. Whether they develop early or late is related to the temperature values of the environment not to DNA.   

Imagine a cherry tree. In a cold place, it blossoms late. In a hot place, it blossoms early. Even in the same place, the time when the tree blossoms changes every year based on the weather conditions of each year.   

Man is like that, too. The puberty of the members of a family that have immigrated to the south from the north changes depending of the temperature of the region that they have immigrated to.
