  • The Greek philosopher who is well-known for believing that species were perfect and unchanging is Aristotle.
  • Aristotle lived from 384 to 322 BCE and made significant contributions to various fields including biology, where he held the view that all life forms could be placed on a hierarchical ladder of complexity known as the "Great Chain of Being" or "Scala Naturae." In this conception, species were fixed in their place on this ladder, and they could not evolve into a different form.
  • Aristotle's view on species and their perfection became a widely accepted view for centuries and was challenged only later by the emergence of evolutionary theories, most notably Charles Darwin's theory of evolution by natural selection.
