Homo Sapiens and Neanderthals: Human Ancestors

Homo Sapiens and Neanderthals: Human Ancestors

Year 13 Science Understanding Human Evolution 30-minute lesson

Learning Objectives

Describe key physical and behavioural differences between Homo sapiens and Neanderthals Explain evidence for coexistence and interaction between species Understand how fossil, genetic, and archaeological data support evolutionary theories Evaluate the significance of human evolution in understanding our heritage

Success Criteria

Accurately identify at least three differences between the two species Use at least two types of evidence to support understanding Participate meaningfully in class discussion with critical thinking Complete reflection connecting learning to evolutionary concepts

Meet Our Ancestors

{"left":"Homo sapiens (modern humans)\nEvolved around 300,000 years ago\nOriginated in Africa\nTall, slender build with high foreheads","right":"Neanderthals (Homo neanderthalensis)\nLived 400,000 to 40,000 years ago\nPrimarily in Europe and western Asia\nStockier build with prominent brow ridges"}

Comparative Analysis Activity

Work in pairs to examine images and fact sheets List physical traits of each species Identify social and technological behaviors Discuss possible interactions between species Use the provided worksheet to record observations

Physical Differences Comparison

Types of Evidence

Fossil Evidence: Skulls, bones, and teeth show physical differences Genetic Evidence: DNA analysis reveals interbreeding and migration patterns Archaeological Evidence: Tools, art, and burial sites show behavioral differences Each type provides different insights into human evolution

Class Discussion

What advantages might each species have had in their environments? How do you think Homo sapiens and Neanderthals interacted? What does the evidence tell us about human adaptability? Why might one species survive while another became extinct?

Key Findings: What We Know

Neanderthals and Homo sapiens coexisted for thousands of years DNA evidence shows interbreeding occurred Both species used tools and controlled fire Neanderthals had larger brains but different skull structure Climate change and competition may have led to Neanderthal extinction

Reflective Summary Task

Individual writing task: 2 paragraphs Paragraph 1: Summarize key differences between the species Paragraph 2: Explain how studying these hominins helps us understand evolution Connect your learning to broader evolutionary concepts Use evidence from today's lesson to support your ideas
