Study Notes
- Evolution is the process of genetic changes in populations that are passed on to successive generations, resulting in physical trait shifts and adaptations for survival.
- Populations are groups of individuals from the same species capable of interbreeding and passing on adaptive changes to offspring.
- Adaptations are beneficial traits that enhance an organism's ability to survive in its environment.
- Both natural and artificial selection are primary factors that cause genetic changes in populations.
- Natural selection refers to the process by which organisms with advantageous traits survive and pass on those traits to their offspring, while artificial selection is the intentional breeding of organisms for specific traits.
- Evolution leads to speciation, the emergence of new species through genetic changes and divergence from a common ancestor.
- In the presented activity, students will breed organisms to achieve specific traits, practicing their crossing skills and understanding the concept of inheritance.
