This series includes drafts of Hrdlička's book, Children Who Run on All Fours, and illustrations, data, correspondence, news clippings, and photographs associated with the book. Hrdlička had begun noting the phenomenon of quadrapedal locomotion in the human child during his first trip to Mexico. Hrdlička assumed this was atavistic behavior harking back to times when our prehuman ancestors used this type of progression. Hrdlička published the results of his studies as Children Who Run on All Fours in 1931.
