Inherited traits from parents can help make combinations of traits that can protect offspring from things like diseases. Charles Darwin was an English naturalist and geologist but he is best known for his contributions to the Theory of Evolution. In 1831, he took a voyage on the HMS Beagle that opened Darwin’s eyes to the idea of evolution. He had one simple idea that all living things are related. Natural selection plays a big role in evolution. There are four parts to natural selection and they are genetic variation, overproduction of offspring, struggle for existence, differential survival and reproduction. My Biology class did another lab called “Origami Bird Lab.”. In this lab we started with three birds made out of paper and straws they all had the same width, circumference, and length. We flew the three birds and whichever bird flew farther bred the next generation of birds. The first offspring of every generation had no mutations while the other two birds in each generation had mutations that were determined by a coin and die. After every generation we flew the birds to see which flew farther. By every generation the birds became better at flying because they adapted to a certain combination that makes them fly farther for example a bird that is smaller and lighter will fly farther because nothing heavy is holding it down. This lab showed why genetic variation is so important to evolution. My biology class did another lab called “Breeding Bunnies”. In the lab we examined a small population of wild rabbits. We put fifty red beads(represent F for fur) and fifty white beads(represents f for furless). Without looking we selected two beans at a time to show the bunnies genotype. If the bunny was recessive (ff) then the bunny would die because they can’t survive the winter. My classes average results showed that after ten generations the gene frequency went from 50% to 11%. Both of these labs
