Unit 1 Family Matters Sibling Science: How Important Is Birth Order? Many families could tell stories about their oldest child who always does well in school and has a stable job. The same families could talk about their younger children who are funny and friendly, but have trouble at school. Some scientists believe that oldest siblings are naturally more organized, while younger ones are more outgoing. Researchers think that there are reasons why birth order could make a difference. The oldest child gets all of the attention from their parents until their younger sibling is born. Experts believe that a head start is enough for those children to do better in school and work in the future. Many doctors, lawyers, and politicians are the oldest children in their families. Younger siblings, on the other hand, always have an older sibling to compete with. They usually choose not to follow in their older sibling s footsteps because the competition is too much. Instead, they find more exciting or artistic careers, like being police officers or musicians. They also have to act differently to get the family s attention, often by being funny or ridiculous. Because of this, people think younger children are friendlier than their older siblings. Other researchers don t believe that personality traits 1, like being organized or adventurous, are decided by birth order. They think the child s environment is more important in shaping those characteristics. The more attention Mom and Dad give to each child, the better off they will be, whether they re studying at law school or art school.

The Magic of Twins Imagine growing up with someone the exact same age as you. From learning how to walk to learning how to drive, every part of your life is shared with someone. For about two percent of the world s population, that s what being a twin means. There are two kinds of twins, identical and fraternal 1. Only eight percent of twins are identical twins. Those two individuals have the exact same DNA and will be very hard to tell apart just by looking. Most twins are fraternal, and they share as much DNA as any two siblings would. Male-female fraternal twins are the most common kind of twins. Many sets of twins talk about a special bond they have with each other. Some describe it as having a soul mate or someone closer than a best friend. There are many stories about twins being able to feel each other s pain. If one twin gets in a car accident, the other twin might feel something even from thousands of miles away. Twins can have very similar ways of thinking. Ron and Roger always had trouble convincing teachers they weren t cheating on tests because they always made the exact same errors. While working in different states, twins Janie and Linda sent their parents the exact same gifts. This twin bond can even be seen in twins that grow up in separate families. Research has found adult twins often share unique habits with their long-lost sibling, like wearing rubber bands on their wrist or walking into the ocean backwards 2. It s often described as something magical and almost impossible to explain, but the twin bond can be seen in all of the examples above. It is a deep love that twins share, the love of people who are really not complete without each other.
