We, the Geology students at the University of Liberia, didn’t say President Boakai shouldn’t dismiss Minister Wilmott Paye ooo, but we just hope that our secondment process remains intact.

"UNCOVERING THE EARTH SECRET, TOGETHER".

12/10/2025

Human evolution is a fascinating journey marked by significant milestones. Modern humans, Homo sapiens, first appeared around 300,000 years ago in Africa. Our closest living relatives are the chimpanzees, with whom we share about 98-99% of our DNA. One of the earliest known ancestors is Australopithecus afarensis, famously represented by the fossil named "Lucy," who lived about 3.2 million years ago.

Around 1.8 million years ago, Homo erectus emerged, known for being one of the first hominins to use fire and develop more sophisticated tools. Neanderthals, another close relative, lived in Europe and parts of Asia until about 40,000 years ago, and recent genetic studies reveal that many modern humans carry a small percentage of Neanderthal DNA.

The development of bipedalism, or walking on two legs, is one of the key adaptations that set early humans apart from other primates, freeing up hands for tool use and manipulation. This shift is believed to have started over 4 million years ago, fundamentally changing how early humans interacted with their environment.
