Here at Purl English, we have recently had a number of orders for cashmere baby gifts especially for twins which led us to research a little into some interesting details about this phenomena.
Twins have fascinated mankind for thousands of years, drawing attention, speculation and intrigue. Yet many still don’t know much about what causes the phenomenon or what it really means to be a twin.
Nearly a fifth of all twins are left handed.
Scientists are not entirely sure how or why so many twins are left-handed, only that it very likely has to do with a connection between a genetic predisposition for twinning and a genetic bias for left handedness. Although why the two are connected is still a mystery.
Rates of twin births vary by location.
Certain areas of the world have much higher rates of twin births than other places. In Massachusetts USA, the twinning rate is 25% higher than the rest of the country. Scientists believe multiple births are a product of many factors including fertility drugs, heredity, food choices and age.
There are seven different types of twin.
These are: identical, fraternal, half-identical, mirror image twins, mixed chromosome twins, superfecundation, and superfetation. Those other than identical and fraternal can be quite rare.
Twins do not have to be born on the same date.
The longest recorded gap between twin births is 85 days, often because one twin is born early due to complications, while the other is left in the womb to further develop.
Twins do not have to have the same father.
It is possible for a woman to give birth to two children on the same day who don’t share a father, known as heteropaternal superfecundation. Very rarely occurring, but genetic testing has shown that it is possible.
Identical twins have different fingerprints.
Identical twins share most of their genetic material, identical fingerprints aren’t among them. While the fingerprints may be very similar, on close examination it is possible to tell them apart – much like the twins themselves.
A quarter of twins are mirror image twins.
This means that they are, in fact, identical, but only in the way that your reflection in a mirror is an identical image of you. For example, if one twin has a mole under her right eye, the other will have it under her left eye.
Identical twins have almost the same brainwave patterns.
It is true to say that twins do think alike as research shows that they have almost perfectly matching brainwave patterns. Some think this could explain how twins know what the other is thinking and feeling.
Twins can develop their own language.
A phenomena known as idioglossia. happening when one twin mimics the incorrect speech patterns of the other. The result sounds a little like a foreign language to others.
Fraternal twins can have very different skin colours.
A very rare phenomenon, when parents of mixed or different races have twins, they can have quite different skin colours upon birth. Fraternal twins don’t share identical genetic material, so one may inherit the genes of one skin colour, the other another.
What a woman eats can help increase her chances of having twins.
Researchers have found that women who eat dairy and animal products are much more likely to have twins than those that don’t. Possibly due to a protein called IGF that increases the sensitivity of the ovaries to hormones that cause ovulation.
So, next on the agenda – we need an order for triplets please ! Keep us posted x
