We should rather say the three gulfs; for between man's body and that of the brute there is a gap which Natural Selection can not cross; another between man's intellectual powers and those of brutes; and the third, and widest of all, between his conscience and their brutal appetites.
The gulf between man's body and that of any brute is marked along the whole line, from the solid basis of the feet, enabling him to stand erect, look upward and behold the stars; along the line of the stiff backbone, maintaining the dignified posture; to the hands, on which treatises have been written, displaying their wonderful superiority over those of all other creatures, and enabling man to do what no other animal has done, to fill the world with his handiworks, and alter the very face of nature with his ax, and spade, and steam engine.

His tongue and organs of articulate speech alone, were there no other characteristic, proclaim him different from all other animals; none of those resembling him in outward form making the slightest attempts toward articulate language or being able to do so.
Man alone, of all the animals, possesses no natural covering, but is exposed naked to the inclemency of the elements.

What little hair he possesses is chiefly on the breast, where it is of little use as a covering, and on the head, which in other animals is never better protected than the body.

Mr.Darwin alleges that the first men were hairy, like apes.

Well, how did they lose their hair?
Not by Natural Selection, which only perpetuates _profitable_ variations; but the loss of hair to an ape would be as unprofitable as the loss of your clothes to you.
