Domesticated animals: The Americas had not seen horses, pigs, or cattle prior to the arrival of the Europeans.

After deportation trains arrived at the killing centers, guards ordered the deportees to get out and form a line. The victims then went through a selection process. Men were separated from women and children. A Nazi, usually an SS physician, looked quickly at each person to decide if he or she was healthy and strong enough for forced labor.

Babies and young children, pregnant women, the elderly, the handicapped, and the sick had little chance of surviving this first selection.
