Natural Selection
What is natural selection?
The process of which species with slightly more fit traits become a larger part of the population.
Where does Genetic Variation come from?
Changes of genes in DNA
What is Adaptation?
Process of an organism going through change to increase their personal fitness.
How did humans discover Natural Selection?
When Charles Darwin took a trip to the
Galapagos Islands. He discovered species that became better fit to the climate of the Island
What results from genetic variation?
Why are mutations Important?
Allow for genetic diversity, leading to more fit species
What is sexual selection?
When females of a species choose a male to mate with.
Why is Genetic Variation Important?
Genetic Variation allows fitness to increase in populations. Without Genetic Variation, we'd all
eventually die out.
What would species look like without Mutations
No diversity in a population
Why is Evolution Important?
What would happen without Genetic Variation?
There would be no diversity in our populations
What do species look like with mutations?
Diverse range of nucleotides. This will cause diverse phenotypes in the species. Allowing them to adapt very well
What species don't survive Natural Selection?
Species that can't become fit, as their climate changes
What species see Genetic Variation the most?
Species who have the most diversity in their habitats
What species could survive without Mutations, when their climate changes and they aren't fit enough?
None! They'd die.
