What is evolution?
Change over time
What is competition?
When species compete for the same resources
Who is Darwin?
A scientist famous for this scientific theory of evolution
What is overproduction?
When a species produces a lot of offspring
What is an example of an evolution mechanism?
What causes genetic variation?
Mutation and recombination
What is mutation?
A change in DNA
What is environmental change?
A change in the environment produced by nature or human activity

Noooo :C
What are the three evolution mechanisms?
Time, natural selection and variation
What are the four factors that affect natural selection?
Heredity, competition, environmental change and overproduction of offspring
What is recombination?
An exchange in genetic material
How can environmental change affect natural selection?
The change in the environment can affect what organisms are the best adapted and can survive, affecting natural selection and what is considered the fittest
Can mutation be controlled or chosen?
No, it occurs by chance (random)
How does time influence evolution?
With time, the unfavorable variations of DNA disappear and the favorable ones remain
How does competition influence natural selection?
The species that is the strongest competes and wins the use of the resources, being the one to survive and being selected naturally to continue with their offspring.
Peaks in birds
What are the two aspects environmental change includes?
Changes in the environment like lack of food and evolutionary adaptations
How does environmental change influence natural selection?
Environmental change may affect the variation that survives the most and creates mutations, changing the better adapted and , therefore, the variation that survives more in time (the fittest)
