Natural Selection
Traits that help organisms survive in a specific environment are called

In order for natural selection to occur, Species must have _______ (hint: differences in traits passed down from parents to offspring) in their populations.
inherited variations
One million years ago, all of the beetles in Arctic Circle were dark green in color. These were the original beetles. One day, a brown beetle was born brown due to a change in DNA

Which of the following is NOT a component of Natural Selection?
Some organisms can better survive and reproduce
Change in population due to gene frequency
Change in the indivisual due to the gene frequency
Inherited Variations
3. Change in the indivisual due to the gene frequency
Inherited variations are differences in traits that can be passed down in DNA/genes from _______ to _____.
parents to offsprings
When Hurricane Katrina hit, many organisms were wiped out in a given region. For example, due to the excessive flooding, many insects that lived underground were wiped out. The entire population of green bugs were killed during the flooding, while half of the brown bugs population were killed, yet some survived..

POPULATION!! THE POPULATION WILL CHANGE
The green beetles lives on an island in Hegenda and the brown beetles live on another island 2 miles away. On brown beetle out the population migrated to Hegenda and found green beetles. Reproduction of the brown beetles and green beetles occurred.

Genus & Species
There may be competition for survival in an environment and some organisms may _____and ____better than others
survive and reproduce
A population of black, brown beetles is moved into an area with grey rocks and white rocks. The brown beetles are able to hide from predators among the grey and white rocks , but the green beetles stand out in both habitats. The brown beetles survive and are able to reproduce increasing the population

In the mechanism of evolution Natural Selection, adaptations will help organisms to better survive and reproduce. Because the organisms can reproduce, we will see an increase in the
Gene frequency in the individuals
Number of genes in the chromosomes
Gene frequency in the population
Number of genes in the species
3. gene frequency in the population
