This is because how the eggs are fertilized. You can compare it to animals in the wild. When you make a zoo and protect them from outside sources they live longer, and when you shelter the eggs from start to finish more of them end up surviving creating a multiple birth.

How common are twins?

Naturally conceived twins occur in approx. 1 in 89 births Identical twins are much more rare than fraternal. They occur in approximately 1 in 250 births. There are things that can increase your chances of having a multiple birth, including a mother being 30 or over when she conceives. For example, while there is a 3% chance of having a multiple birth at age 25-29, it increases to 4% at 30-34 years and almost 5% at 35-39 years. Other factors that can increase your chances of having twins include having a maternal family history of multiple births (fraternal), and of course, using fertility treatments (in vitro fertilization or fertility drugs). Your chance of having twins is also influenced by your race (multiples are more common in African Americans and least common in Hispanics and Asians), how many times you have been pregnant (the chance of having twins increases with each pregnancy), and whether or not you have had twins already.
