The killer ape theory or killer ape hypothesis is the theory that war and interpersonal aggression was the driving force behind human evolution.It was originated by Raymond Dart in his 1953 article "The predatory transition from ape to man"; it was developed further in African Genesis by Robert Ardrey in 1961.

Cave paintings (such as this one from France) represent a benchmark in the evolutionary history of human cognition. Victorian naturalist Charles Darwin was the first to propose the out-of-Africa hypothesis for the peopling of the world, [39] but the story of prehistoric human migration is now understood to be much more complex thanks to twenty-first-century advances in genomic sequencing.
The first space rendezvous was accomplished by Gemini 6A and Gemini 7 in 1965.. Records and firsts in spaceflight are broadly divided into crewed and uncrewed categories. Records involving animal spaceflight have also been noted in earlier experimental flights, typically to establish the feasibility of sending humans to outer space.
Prehistoric warfare refers to war that occurred between societies without recorded history.. The existence—and the definition—of war in humanity's hypothetical state of nature has been a controversial topic in the history of ideas at least since Thomas Hobbes in Leviathan (1651) argued a "war of all against all", a view directly challenged by Jean-Jacques Rousseau in a Discourse on ...
Space and survival is the idea that the long-term survival of the human species and technological civilization requires the building of a spacefaring civilization that utilizes the resources of outer space, [1] and that not doing this might lead to human extinction. A related observation is that the window of opportunity for doing this may be ...
The next step of commercialization of space was seen as human spaceflight. Flying humans safely to and from space had become routine to NASA and Russia. [75] Reusable spacecraft were an entirely new engineering challenge, something only seen in novels and films like Star Trek and War of the Worlds.
The earliest fictional references appear to deal with interplanetary, not interstellar war (e.g. H. G. Wells' 1898 novel The War of the Worlds). [5] Writers such as Larry Niven have developed plausible interplanetary conflict based on human colonization of the asteroid belt and outer planets by means of technologies utilising the laws of physics as currently understood.
Orson Scott Card's Ender's Game series is a notable example in that it makes a conjecture as to what sort of tactics and training would be needed for war in outer space. Other scifi authors have also delved into the tactics of space combat, such as David Weber in his Honorverse series, and Larry Niven and Jerry Pournelle in their Mote in God's ...
