<h3>Puberty</h3>

The transition from a child to an adult is caused by changes in the level of some hormones in the body.

In females, there is an increase in follicle-stimulating hormones as well as luteinizing hormones, leading to an increase in the production of progesterone.

In males, there is an increase in the production of testosterone hormone among many other hormones.

Both progesterone and testosterone are responsible for the development of physical features in females and males respectively.

The organisms which are placed more closer together in a cladogram show that these organsims are more closer to one another and might have evolved from a common ancestor in the near past. These organisms show more similarities with each other as compared to other organisms in the cladogram.

As lizards and snakes are more closely related to one another, it shows that they are more genetically alike.
