When did we start studying the stars?
The first documented records of systematic astronomical observations date back to the Assyro-Babylonians around 1000 BCE.

How did humans come into existence?
Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.
How long will humans survive on earth?
Humanity has a 95% probability of being extinct in 7,800,000 years, according to J. Richard Gott’s formulation of the controversial Doomsday argument, which argues that we have probably already lived through half the duration of human history.
When did humans appear?
300,000 years ago
Can humans grow wings?
Now let’s look at why humans can’t grow wings. All living things, including vertebrates, have genes. In fact, a spider’s own hox genes are what give it eight legs. So one main reason humans can’t grow wings is because our genes only let us grow arms and legs.
Which body part is vestigial in humans?
Charles Darwin listed a number of putative human vestigial features, which he termed rudimentary, in The Descent of Man (1871). These included the muscles of the ear; wisdom teeth; the appendix; the tail bone; body hair; and the semilunar fold in the corner of the eye.
Did humans ever have gills?
Artificial gills are unproven conceptualised devices to allow a human to be able to take in oxygen from surrounding water. This is speculative technology that has not been demonstrated in a documented fashion.
