Why humans give birth mostly to a single child but Animals give mare than three babies ?
Answers
Explanation:
But seriously, there are several reasons for this. Part of this is because most human babies have a fair chance of survival, as their mother takes care of them until they are big enough to take care of themselves or can at least eat, walk and play on their own. Advances in medical science also mean that there is a very good chance of a human baby surviving, even if it has some kind of a disease or illness or infection. And there are no other humans in the vicinity- stronger ones- trying to eat or destroy human babies.
Also, as a bi-ped, meaning a being which stands upright and walks on two legs, delivery is an extremely difficult and painful process, very taxing on the mother and difficult. And there are complications quite often, thank goodness for hospitals and medical assistance on hand. Which again means there is an almost 100% chance of the human baby, and it’s mother surviving childbirth.
Not so in the case of other animals. Of course, in the case of animals too larger mammals give birth to only a single young- camels, elephants, zebra, horses, antelope etc. The herd or group protects the young and at any rate the young are able to stand up and run or keep up with their mothers within minutes of birth. Meaning the young of large mammals have a fair chance of survival as well. And the female of the species is invariably more ferocious and dangerous than the male (applies to humans too, but that’s another story!!), so that maternal instinct ensures that few animals mess with the young of these large animals- if they do, they face serious consequences with the mother rushing to their rescue.
Other animals give birth to a litter (or a clutch of eggs at a time which mean a litter of new born). These are however vulnerable to attack and predation by other species. So apart from providing food to other species, most of the young of the litter end up getting destroyed or eaten by predators, or dying due to extreme conditions, so it is necessary for the animal to produce a litter so that at least one or two of them survive into bigger animals. Imagine the disaster if all crocodiles which hatch or all snakes which hatch were to survive! They would destroy all local wildlife and make it extremely dangerous for us humans to survive as well. f the tens of thousands of turtles which hatch from the nesting sites, barely a handful will survive for the same reason.
So animals being born in a litter is to give at least a couple of them a chance of survival, and it’s nature’s way of preventing overpopulation of any particular species and to conserve it’s resources.
One final point, although you see almost all ducklings in a batch or chickens in a batch hatch alright, with the mother severely protective of their young (ducks, geese and poultry fearlessly charge other animals which try to harass their chicks), many of the young do get taken by foxes, dogs, humans and stuff, so protection apart, many of the chicks will die out as well, unfortunately.
