Answer 1:
Puberty is the period of the development of organs
used in reproduction, the transition from a
juvenile life to adult life. All multicellular
organisms, animals and plants alike, do it,
although in some the changes are more obvious than
others.
Organisms that are too young may not be able to
allot the nutrients and energy to reproduce, so
don't do it until they reach a certain age or
size.
In humans, puberty also causes a number of
other changes that are not related to
reproduction, the growth of body hair being an
example. Why this happens I don't think anybody
knows, but it may have to do with something called
sexual selection (choosing of mates). It also may
have been something that was important to our
ancestors, but no longer matters for modern
humans, and remains as an evolutionary relic.
