One of the scientists studying the family believed that these issues, combined, are what causes this family to walk on both their hands and feet. He had another theory, believing that this was also what he called reverse evolution. There was a lot of backlash from the scientific community based on the impossibly.

This comparison showed that the family’s walk was actually very similar to that of other humans who walk on all fours than to that of quadrupedal animals. Continuing his theory other scientists, such as Liza Shapiro, believed that the family walked on all fours as an adaptation to the condition that they had.

On the other side of the debate, many believe that the family’s quadrupedal walk is caused by the environment they were raised in. Typically, around the age of 2 children who are still crawling on their hands and knees or are still bear crawling (walking on hands and feet rather than hands and knees) are taken to physical therapy to learn how to walk on their feet alone.
