Fundamentally, science is about discovering the underlying simplicity behind the mystery and complexity of phenomena. And Charles Darwin did just that when he discovered that the diversity of plant and animal species on Earth and the morphological change in plant and animal species found in the fossil record was predominantly due to biological evolution through natural selection.
The Voyage of Charles Darwin was a BBC biographical miniseries that was originally hosted by astronaut Neil Armstrong when it was first broadcast in the US on PBS. Its a magnificent reflective journey by Charles Darwin aboard the HMS Beagle, a journey, of course, which later helped Darwin to develop his theory of 'Evolution through Natural Selection'.
