Answer 1

NASA helped to distinguish genetic factors from environmental ones when studying the effects of living in space by analyzing changes in one twin on Earth and the other in space. This unique approach allowed researchers to compare the genetic similarities and differences between the twins while controlling for the environmental factors that come with space travel.
