As well as species been physically and chemically similar, they are also similar
in the way in which they act their behaviour. Species behave in a certain way
to establish members of their own species, this is especially the case when
Why is courtship behaviour necessary?
Species want to make sure that their DNA is passed down through generations,
but sometimes females only produce eggs as little as once a year, so getting the
timing right is essential. There are various reasons why courtship behaviour is
To identify members of the same species only members of the same
species can produce fertile offspring
To form a pair bond This will lead to successful mating and raising up of
To synchronise mating So that it takes place with maximum chances of
To identify a mate which is capable of breeding Both partners need to
be sexually mature, fertile and receptive to breeding
Females undergo times of sexual activity and this is usually around the time at
which she produces eggs. To recognise members of the same species and
times at which the female is fertile, a series of actionsequences take place.
This is usually in the form of the male carrying out some action, if the female
responds with the correct sequence of actions, mating takes place. If she's not
receptive, the male turns his attention elsewhere.
If the female doesn't respond
She may not be at the fertile stage of her sexual cycle
She may not be a member of the same species
Why courtship is so necessary
If the female doesn't respond, the male can turn his attention elsewhere. This is
so the male can court with another female, if he carried on trying to court the
same female, he probably wouldn't get anywhere and reproduction is essential
to any species survival.
