Oldest footprint in Europe survived nearly 6 million years

This step is a step towards knowing when humans reached Europe

Discovery of a 5.7-million-year-old human footprint on the Greek island of Crete challenges existing assumptions about ancient hominin (meaning human species) biogeography. It was previously thought that during this time period, called the Miocene, hominins lived in Africa and had ape-like feet.

Or, this footprint belongs to a hominin-like primate. However, this breaks Occam’s Razor test which states that the simplest answer is probably correct. So, if analysis of the print looks like, acts like, and is built like a human foot, it’s probably a human foot.

Could humans even survive a trek eastward out of Africa, around the Mediterranean Sea, to Crete? Gerard Gierlinski of the Polish Geological Institute says the Sahara didn’t exist so there would’ve been enough hospitable environments for humans to oasis-hop the entire length of the journey.
