Final answer:
The oldest evidence of anatomically modern humans outside of Africa was discovered in Jebel Irhoud in Morocco, dated to about 300,000 years ago. The evidence of early human presence in eastern Europe includes Paleolithic shelters made of mammoth bones. More recent evidence suggests humans arrived in the Western Hemisphere during the last Ice Age, approximately 11,000 years ago, or earlier based on new discoveries.
Step-by-step explanation:
The oldest evidence of anatomically modern humans (AMHS) outside of Africa was found in the Middle East, and specifically at the site of Jebel Irhoud in Morocco. This site has been dated to about 300,000 years ago, which pushes back the date of the earliest known Homo sapiens outside Africa. Additionally, archaeological finds in Asia and Europe, such as the evidence of Paleolithic shelters made of mammoth bones in eastern Europe, indicate early human presence. The arrival of humans in the Americas came much later, with the earliest evidence now estimated at around 15,000 to 20,000 years ago. That being said, some sites in North and South America are suggesting a possibly earlier arrival, as evidenced by recent archaeological discoveries and the use of scientific techniques, such as C14 dating of charcoal. In these sites, analysis of charcoal samples, as per Exercise 21.6.2, has indicated that humans might have arrived in the Western Hemisphere during the last Ice Age approximately 11,000 years ago, or potentially earlier based on some disputed finds.
