Note 205 — Chapter IV
Reading edition
Häckel has an excellent discussion on the steps by which man became a biped: ‘Natürliche Schöpfungsgeschichte,’ 1868, s. 507. Dr. Büchner (‘Conférences sur la Théorie Darwinienne,’ 1869, p. 135) has given good cases of the use of the foot as a prehensile organ by man; also on the manner of progression of the higher apes to which I allude in the following paragraph: see also Owen (‘Anatomy of Vertebrates,’ vol. iii. p. 71) on this latter subject.
