  2. Evolution of human intelligence - Wikipedia

    en.wikipedia.org/wiki/Evolution_of_human...

    Another hypothesis is that it is actually intelligence that causes social relationships to become more complex, because intelligent individuals are more difficult to learn to know. [24] There are also studies that show that Dunbar's number is not the upper limit of the number of social relationships in humans either. [25] [26]

  3. Potential cultural impact of extraterrestrial contact - Wikipedia

    en.wikipedia.org/wiki/Potential_cultural_impact...

    Michael A. G. Michaud suggests that a friendly and advanced extraterrestrial civilization may even avoid all contact with an emerging intelligent species like humanity, to ensure that the less advanced civilization can develop naturally at its own pace; [50] this is known as the zoo hypothesis.

  4. Uplift (science fiction) - Wikipedia

    en.wikipedia.org/wiki/Uplift_(science_fiction)

    In science fiction, uplift is the intervention in the evolution of species of low-intelligence or even nonsentient species in order to increase their intelligence. [1] This is usually accomplished by cultural, technological, or evolutionary interventions such as genetic engineering.

  5. Silurian hypothesis - Wikipedia

    en.wikipedia.org/wiki/Silurian_hypothesis

    The most probable clues for such a civilization could be carbon, radioactive elements or temperature variation. The name "Silurian" derives from the eponymous sapient species from the BBC science fiction series Doctor Who, who in the series established an advanced civilization prior to humanity, though not from the eponymous geological period.

  6. Animal cognition - Wikipedia

    en.wikipedia.org/wiki/Animal_cognition

    Cognitive maps Some animals appear to construct a cognitive map of their surroundings, meaning that they acquire and use information that enables them to compute how far and in what direction to go to get from one location to another. Such a map-like representation is thought to be used, for example, when an animal goes directly from one food ...

  7. Rare Earth hypothesis - Wikipedia

    en.wikipedia.org/wiki/Rare_Earth_hypothesis

    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 ...

  8. That is a question that can even blow the minds of theoretical physicists, but the parameters which were thought to be necessary for life (and intelligence with it) to exist might not be as ...

  9. Cephalopod intelligence - Wikipedia

    en.wikipedia.org/wiki/Cephalopod_intelligence

    Though these criteria are difficult to measure in nonhuman animals, cephalopods are the most intelligent invertebrates. The study of cephalopod intelligence also has an important comparative aspect in the broader understanding of animal cognition because it relies on a nervous system fundamentally different from that of vertebrates .
