Johannesburg: Why 'Mrs. Ples' Might Not Even Be a Woman

By Travelog Editorial Team ยท Updated August 10, 2026

The Cradle of Humankind, UNESCO World Heritage-listed in 1999, sits within the Sterkfontein Caves roughly 40 kilometers northwest of Johannesburg, not inside the city itself, stated honestly here. The site holds the world's richest deposit of Australopithecus fossils, including 'Mrs. Ples,' the most complete Australopithecus africanus skull ever found, discovered in 1947 and dated to roughly 2.05 million years old, though researchers still debate whether the skull actually belonged to a female, or even an adult. A separate find, 'Little Foot,' is the most complete Australopithecus skeleton ever found in Africa, dated to 3.67 million years old.

Why "Mrs. Ples" might actually be a misnomer worth knowing before visiting

Despite its widely used nickname, researchers genuinely still debate whether the skull belonged to a female, or even an adult, an ongoing scientific uncertainty rather than a settled fact.

Why "Little Foot" and "Mrs. Ples" represent two separate, distinct discoveries

The two fossils were found decades apart and dated to different ages, roughly 2 million versus 3.67 million years, two genuinely independent fossil finds rather than parts of the same discovery.

Why the honest ~40km distance from Johannesburg matters for trip planning

Stated plainly rather than implied otherwise, the Cradle of Humankind is a genuine day-trip destination from Johannesburg, not a site located within the city itself.

Getting there

The Cradle of Humankind and Sterkfontein Caves sit roughly 40 kilometers northwest of central Johannesburg.

The bottom line

Johannesburg rewards understanding both the genuine scientific uncertainty behind "Mrs. Ples" and the honest distance to the Cradle of Humankind itself. The Apartheid Museum and Constitution Hill are covered in full below.

  • Apartheid Museum Opened 2001, the first institution in the world built specifically to document apartheid, including a chamber of 131 nooses.
  • Constitution Hill A former prison that once held Mahatma Gandhi, now the seat of South Africa's Constitutional Court.
