Secondly, the essay confronts the question of cognition and ontology, suggesting that the human brain is not inherently distinct from the brains of other mammals, but that human intellectual capabilities developed through a dialectical relationship with the human body. Specifically, Engels emphasizes the importance of humans’ opposable thumbs ...
This ability is most likely an example of convergent evolution, due to their distant relatedness. Mammals. Humans possess possibly the highest level of cognitive function on earth. Some examples of their cognitive function include: high levels of motivation, self awareness, problem solving, language, culture, and many more. [5] [6] [7]
Nuclear war is an often-predicted cause of the extinction of humankind. [1]Human extinction or omnicide is the hypothetical end of the human species, either by population decline due to extraneous natural causes, such as an asteroid impact or large-scale volcanism, or via anthropogenic destruction (self-extinction), for example by sub-replacement fertility.
Merlin Donald has claimed that human thought has progressed through three historic stages: the episodic, the mimetic, and the mythic stages, before reaching the current stage of theoretic thinking or culture. [2] According to him the final transition occurred with the invention of science in Ancient Greece. [3]
In fact, humans have shown an enormous increase in brain size and intelligence over millions of years of evolution. [39] This is because humans have been referred to as an 'evolved cultural species'; one that has an unrivalled reliance on culturally transmitted knowledge due to the social environment around us. [40]
Machery argues that while the idea that humans have an "essence" is a very old idea, the idea that all humans have a unified human nature is relatively modern; for a long time, people thought of humans as "us versus them" and thus did not think of human beings as a unified kind. [90]
Evolutionary thought, the recognition that species change over time and the perceived understanding of how such processes work, has roots in antiquity. With the beginnings of modern biological taxonomy in the late 17th century, two opposed ideas influenced Western biological thinking: essentialism, the belief that every species has essential characteristics that are unalterable, a concept ...
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, [40] but the story of prehistoric human migration is now understood to be much more complex thanks to twenty-first-century advances in genomic sequencing.
