Question

How do the mothers of the animal kingdom know their young ones?

Answer 1

It is a familiar scene in real life and in movies. In a group of 100 excited lambs, an ewe, or female sheep, has no problems picking out her lamb. She does this through the sense of smell.
More than one million animal species live on our planet and the females of the species recognise their young ones through smell, sound, sight or touch.
