fossil evidence

Scientists have discovered that human origins are more complex than previously believed, with multiple intermingling populations in Africa contributing to the evolution of early humans over hundreds of thousands of years. Genetic data from groups like the Nama people and fossil evidence suggest gene exchange persisted even after populations began diverging around 120,000–135,000 years ago.

Fossil evidence suggests giant octopuses, up to 19 meters in size, may have dominated ancient oceans 100 million years ago. The discovery highlights the evolutionary history of cephalopods and their dominance in prehistoric marine ecosystems.
