The term “human” has been around since the 1500s.
The term is used to describe a person whose genes and anatomy are similar to those of humans and their culture.
In the early 1900s, scientists began to explore the idea that some people were genetically identical to other people.
These findings, known as the HLA hypothesis, became the foundation for the current definition of “human.”
However, many people who were born with the genes and physical characteristics of people with Down syndrome are not considered to be human.
As a result, the term is often used interchangeably with “aliens.”
That means “people from another planet.”
For some, that’s an insult.
For others, it can be a point of pride.
In 2016, an alien-inspired poster was discovered in a bathroom in a California town.
The poster, with its black-and-white artwork, said “I’m from a planet with a different name.
It is called ‘Down Syndrome’ and I love my planet.
Thank you for your help.”
It wasn’t immediately clear whether the poster was the work of an extraterrestrial or human creator.
But according to the National Institutes of Health, people with certain genetic and environmental differences can be considered “aliends,” and are considered “unusual.”
And if they have a child with Down Syndrome, they’re considered “human beings.”
