29. Koalas have fingerprints.
Chimpanzees and gorillas have fingerprints similar to humans, but surprisingly so do koalas. Indeed, koala prints are very similar to human fingerprints, even to expert crime scene investigators. No koalas have yet framed human beings for their crimes, but now we realize it is not impossible…
30. Humans are just one of the estimated 8.7 million species on Earth.
With our vast cities and far-reaching technologies, human beings may dominate the world, but we are, in reality, only one of some 8.7 million species that live together on Earth. A 2011 study published in the journal PLoS Biology estimated that “the various forms of life on the planet included 7.8 million species of animals, 298,000 species of plants, 611,000 species of mushrooms, mold and other fungi, 36,400 species of protozoa, and 27,500 species of algae or chromists.”
And it should be noted that the researchers did not venture to provide an estimation of the number of bacteria.
