Researchers found gender-differing spines in men and women develop at birth rather than over time, based on a study published in the Journal of Pediatrics, according to Softpedia.
Here are five key points:
1. The new study builds on the scientifically accepted fact that male spines have bigger cross-sections than female spines.
2. Researchers at the Children's Hospital Los Angeles found that the difference between male and female spines is already existent at birth.
3. The team spotted the difference in newborn boys and girls with MRIs, which revealed the female vertebral cross-section is an average of 10.6 percent smaller.
4. As of now, this discovery has only been found in humans.
5. Scientists believe the discrepancy exists between men and women so that women can stabilize their center of gravity while pregnant.
