Evolution and Natural Selection
• Explain why natural selection is important for populations?
It can Cause or prevent extinction of a species
Tuberculosis example
bacteria that cause tuberculosis have variation in antibiotic resistance
Antibiotics are introduced into the bacteria's environment
Bacteria without Antibiotic resistance die while others with survive
If antibiotics stop being introduced bacteria reproduce
Resulting in stronger less curably tuberculosis as the bactieria population has higher frequency of Antibiotic resistance

• What is evolution by natural selection?
Natural selection
the process through which populations of living organisms adapt
that drives evolution
Evolution
any change in the genetic traits in a population over many generations.
• What are the key features of evolution by natural selection?
Survival
Individuals that have the right adaptations survive and pass down their genes
Variation
Variation of traits in a population
Time
Over time there is higher frequency of the Adaptation/Suitable trait
Inheritance
traits of individuals are able to be passed down to their offspring
