"The First Born of Barsoom," he explained, "are the race of black men of which I am a Dator, or, as the lesser Barsoomians would say, Prince. My race is the oldest on the planet. We trace our lineage, unbroken, direct to the Tree of Life which flourished in the centre of the Valley Dor twenty-three million years ago.From The Gods of Mars by Edgar Rice Burrows"For countless ages the fruit of this tree underwent the gradual changes of evolution, passing by degrees from true plant life to a combination of plant and animal. In the first stages the fruit of the tree possessed only the power of independent muscular action, while the stem remained attached to the parent plant; later a brain developed in the fruit, so that hanging there by their long stems they thought and moved as individuals.
"Then, with the development of perceptions came a comparison of them; judgments were reached and compared, and thus reason and the power to reason were born upon Barsoom.
"Ages passed. Many forms of life came and went upon the Tree of Life, but still all were attached to the parent plant by stems of varying lengths. At length the fruit tree consisted in tiny plant men, such as we now see reproduced in such huge dimensions in the Valley Dor, but still hanging to the limbs and branches of the tree by the stems which grew from the tops of their heads.
"The buds from which the plant men blossomed resembled large nuts about a foot in diameter, divided by double partition walls into four sections. In one section grew the plant man, in another a sixteen-legged worm, in the third the progenitor of the white ape and in the fourth the primaeval black man of Barsoom.
"When the bud burst the plant man remained dangling at the end of his stem, but the three other sections fell to the ground, where the efforts of their imprisoned occupants to escape sent them hopping about in all directions.
"Thus as time went on, all Barsoom was covered with these imprisoned creatures. For countless ages they lived their long lives within their hard shells, hopping and skipping about the broad planet; falling into rivers, lakes, and seas, to be still further spread about the surface of the new world.
"Countless billions died before the first black man broke through his prison walls into the light of day. Prompted by curiosity, he broke open other shells and the peopling of Barsoom commenced.
"The pure strain of the blood of this first black man has remained untainted by admixture with other creatures in the race of which I am a member; but from the sixteen-legged worm, the first ape and renegade black man has sprung every other form of animal life upon Barsoom.
"The therns," and he smiled maliciously as he spoke, "are but the result of ages of evolution from the pure white ape of antiquity. They are a lower order still. There is but one race of true and immortal humans on Barsoom. It is the race of black men.
"The Tree of Life is dead, but before it died the plant men learned to detach themselves from it and roam the face of Barsoom with the other children of the First Parent.
"Now their bisexuality permits them to reproduce themselves after the manner of true plants, but otherwise they have progressed but little in all the ages of their existence. Their actions and movements are largely matters of instinct and not guided to any great extent by reason, since the brain of a plant man is but a trifle larger than the end of your smallest finger. They live upon vegetation and the blood of animals, and their brain is just large enough to direct their movements in the direction of food, and to translate the food sensations which are carried to it from their eyes and ears. They have no sense of self-preservation and so are entirely without fear in the face of danger. That is why they are such terrible antagonists in combat."
