The term non-human has been used to describe computer programs and robot-like devices that display some human-like characteristics.

Haeckel claimed that human evolution occurred in 24 stages and that the 23rd stage was a theoretical missing link he named Pithecanthropus alalus ("ape-man lacking speech"). [9] Haeckel claimed the origin of humanity was to be found in Asia. He theorized that the missing link was to be found on the lost continent of Lemuria located in the ...
Many proponents of animal rights hold that if animals and humans are of the same nature, then rights cannot be distinct to humans. Charles Darwin, in fact, considered "sympathy" to be one of the most important moral virtues — and that it was, indeed, a product of natural selection and a trait beneficial to social animals (including humans ...

One, which he calls "objectivism", tries to counter the overemphasis of the subjective, or intersubjective, that pervades humanism, and emphasises the role of the nonhuman agents, whether they be animals and plants, or computers or other things, because "Humans and nonhumans, it ...
He argued that non-human animals can reason, sense, and feel just as human beings do. [9] Theophrastus did not prevail, and it was Aristotle's position—that human and non-human animals exist in different moral realms because one is rational and the other not—that persisted largely unchallenged in the West for nearly two thousand years.
While elements of Victorian England opposed the idea of Darwinism, Hindus already had the present notion of common ancestry between humans and animals. [3] While the creation–evolution controversy has seen much debate in US, Middle East and parts of Africa, it is an insignificant issue in India, because of its Hindu-majority population.
