What Does It Mean to be "Human"?
10
The criteria of what makes us human is something that has troubled scientists for a very long time. We want humans to be exceptional and special, not just another animal. But throughout history, the criteria chosen to define “human” also excludes.

How scientists classified a “human” vs. an “animal” varied throughout history and was dependent not only on science but also on contemporary religious and cultural ideas. The Greek philosopher Aristotle defined humans as having “rational souls” in addition to the animal’s “sensitive soul.” In the 18th century, Carl Linnaeus, the father of biological classification, created subcategories for monstrous or abnormal humans in his Systema Naturae (1735), a taxonomy that reflected not only Linnaeus’ natural theology (God’s wisdom is revealed through the study of creation) but also the discoveries of global exploration.
In the 20th century, genetic science illustrated the ambiguity that exists between was is “human” and what is “animal” through DNA sequencing. For example, humans and gorillas share 98.4% of their DNA; humans and mice, 90%. Primatologists have proven that some primate species are capable of language, as are some marine mammals. Elephants can recognize themselves in a mirror, a trait once thought only to be human.
Do these discoveries make us question what it means to be “human?”
