The evolution of human intelligence is closely tied to the evolution of the human brain and to the origin of language. The timeline of human evolution spans approximately seven million years, [ 1 ] from the separation of the genus Pan until the emergence of behavioral modernity by 50,000 years ago.
The Rare Earth hypothesis argues that planets with complex life, like Earth, are exceptionally rare.. In planetary astronomy and astrobiology, the Rare Earth hypothesis argues that the origin of life and the evolution of biological complexity, such as sexually reproducing, multicellular organisms on Earth, and subsequently human intelligence, required an improbable combination of astrophysical ...
Did snakes evolve from burrowing lizards or aquatic lizards? There is evidence for both hypotheses. Origin of turtles. Did turtles evolve from anapsids or diapsids? There is evidence for both hypotheses. Paleodictyon: What is the origin of this trace fossil and its modern counterparts? Despite many theories proposed, no evidence has been found ...
The Moon's heavily cratered far-side. The origin of the Moon is usually explained by a Mars-sized body striking the Earth, creating a debris ring that eventually collected into a single natural satellite, the Moon, but there are a number of variations on this giant-impact hypothesis, as well as alternative explanations, and research continues into how the Moon came to be formed.
More than 50 years after humans first began soft-landing spacecraft on the moon, it remains a treacherous feat with more than half of missions failing. Here’s why.
This calculation arrives at the estimated figure of 100 million worlds where life has been forged by evolution." [12] Seven months after Cocconi and Morrison published their article, Drake began searching for extraterrestrial intelligence in an experiment called Project Ozma. It was the first systematic search for signals from communicative ...
Did you ever wonder why the full moon seems so big and bright in the winter? Because the Earth’s axis is tilted about 23.5 degrees to its orbit around the sun, the sun appears at different ...
There has been a gradual increase in brain volume as the ancestors of modern humans progressed along the human timeline of evolution (see Homininae), starting from about 600 cm 3 in Homo habilis up to 1736 cm 3 in Homo neanderthalensis. Thus, in general there is a correlation between brain volume and intelligence. [27]
