Humans have been active on earth throughout the Holocene. Look at the big changes in megafauna at the start of the period .. mammoths, mastodons, sabertooths, scimitar cats, giant short faced bears, giant ground sloths and more all disappeared. Horses, zebras, camels, cheetahs which originated in North America disappeared there. Humans used fire to reshape plant growth thousands of years ago.
