Learn how different animals reproduce.
All animals need to make copies of themselves, or they wouldn't exist anymore.
It's what life's all about.
Of course they can't just put themselves into a photocopier.
Although some very simple kinds of creatures, like bacteria, do simply make copies of themselves.
They just divide in two, and that's that.
Most creatures have male and female versions though. They can only make a new copy if they mix together males and females.
That's what we call mating.
Females get pregnant after mating. And if they're insects, or fish, or birds, or reptiles, they lay eggs.
Us mammals are unusual though鈥
鈥e don't lay eggs. Our females keep their babies inside their own bodies, until they have developed enough to survive in the world.
Reproduction
To reproduce, animals need a male and female.
Together they can create offspring, or babies.
Some animals, such as chickens, fish and snakes, lay eggs which contain their offspring.
Other animals, including humans, tigers and sheep, grow their babies inside them until they are developed enough to be born.
