What are the main factors that drive natural selection?
Genetic variation and environmental pressures
The belief that species were created in their present form
The idea that living organisms have not changed over time
The study of the origins of life on Earth
How does the concept of natural selection challenge traditional views of the natural world and our place within it?
By suggesting that species are not fixed or unchanging, but rather constantly evolving
By challenging the idea that humans are uniquely special or separate from other species
By revealing the interconnectedness and complexity of all living organisms
