This document discusses human origins from both mainstream and opposing viewpoints. The mainstream view is that Homo habilis emerged 2.4 million years ago, followed by Homo erectus 1.8 million years ago, Neanderthals 250,000 years ago, and Homo sapiens 200,000 years ago. Evidence for this includes morphological similarities between species and archaeological remains. However, the opposing view cites forbidden discoveries of human artifacts over 250,000 years old and human footprints over 100 million years old. DNA evidence also suggests other species did not contribute to the modern human genome. There are still many open questions around human origins.

Paleontology, Genetics.
• The Stone-Bronze-Iron Ages
• Ancient- middle ages- modern

4. Opinion of the mainstream
• Homo habilis 2.4 million to 1.4 million.
• Homo erectus 1.8 million to 300,000.
• Neanderthals 250,000 to 30,000.
• Home sapiens, appeared 200,000 years ago.

5. Opinion of the mainstream
• Morphological evidence: similar body parts
• Archeological evidence: human-like remains
• Genetic evidence:

6. Opinion of the mainstream
• Multiregional hypothesis:

7. • Out of Africa hypothesis:
Opinion of the mainstream

8. The opposing opinion
• Forbidden discoveries:
Human artifacts in Mexico (250 thousands).
Human foot prints as old as 100 million years.

9. • DNA findings showed that other species were
unlikely to have contributed to the modern
human genome.
• They are different species that had gone
extinct.
