Transcript of Parenting in the animal kingdom

The number offspring per birth usually depends on the species and fertility.
The same will go for how long the pregnancy is and the age at which they are able to reproduce.
There are also many different parenting styles, as in how they're taken care of and when they're forced to "fly the coop" or be out on their own.
We'll be discussing and exploring how we differ from each other and other species of animals.
What we'll be learning
Parenting in different species
On average a human will have 2-3 children during their lifetime. Only 3.3 of U.S pregnancies end up with multiple births.
While animals can give birth to as many as 1-60 babies in a single pregnancy, depending on the animal.
Number of births
Very few animals have single births, such as horses, donkeys, kangaroos, monkey, bears, deer, dolphins, and whales.
Mammals will have anywhere from 1-10 offspring, while the births of up to 60 are from reptiles such as snakes are common.
Spiders have been known to have hundreds of babies in one birth.

Number of births cont.
Humans are able to have children at a average of 12 years old, but the average age at which we have children is 25 years old.
The maturity age of animals varies greatly from as young as 2 weeks (marsupials) to as old as 14 years (elephants).
Age of maturity
Humans of an average gestation period of 9 months.
The shortest gestation period of any animal is 15-17 days for hamsters, while the longest is the Elephant at 1.5-2 years.
The whale is a close second with 1-1.5 years.
Length of term
When it comes to raising children humans can range from doing everything for their child, doing nothing, letting them leave when they're ready, or kicking them out as soon as it's legal. There is no specific or right way to do things, it's all up to the parent.
With animals is different, because depending on the species they have a way of nature and don't question it. It's just how it's done.
Raising children
Humans are legally allowed to force a child from their home at the age of 18.
Animals range from always being there to not at all. A female infant elephant will remain with their herd and mother for life, while a male will be kicked out within 2-4 years. Some animals, such as turtles, will lay eggs and leave the infants to hatch and possibly survive on their own. Few animals will actually eat their young, like certain sharks, chickens, polar bears, spiders, and a couple others.
Rasing children cont.
Unlike animals in nature we're given the choice on how and when to raise our young. We can even choose if we want them at all unlike animals where it's a biological necessity. Animals reproduce to ensure the survival of their species, we have them to pass on genetics and because we can or want to.
