"It is a well-established fact that the skeleton responds to loads during life, adding bone to resist high forces and subtracting bone when forces are reduced," said John Kappelman, an anthropology professor at the University of Texas, and one of the main authors of the research.
"Tas ir labi zināms fakts, ka skelets dzīves laikā reaģē uz slodzi, palielinot kaulu, lai pretotos lielai slodzei, un samazinot kaulu, kad slodze tiek samazināta," skaidroja Teksasas universitātes profesors Džons Kapelmans, kurš ir viens no pētījuma autoriem.
