Charles DarwinCharles Darwin
Charles Darwin was a naturalist Charles Darwin was a naturalist
He took a trip on the HMS Beagle to the He took a trip on the HMS Beagle to the Galapagos islands Galapagos islands
Mainly studied finches and turtles iguanas Mainly studied finches and turtles iguanas during his time in the Galapagos islands during his time in the Galapagos islands
By studying these creatures he came up By studying these creatures he came up with the idea of natural selectionwith the idea of natural selection
He wrote a book He wrote a book The Origin of SpeciesThe Origin of Species
His Examples His Examples
Darwin identified 13 species of finches Darwin identified 13 species of finches
He noticed that each of the finches were He noticed that each of the finches were different different
They were all different from the size and shape They were all different from the size and shape of the beakof the beak
Then he noticed that the diet was different Then he noticed that the diet was different based on the beak based on the beak
ExamplesExamplesExample: big beaks were good for cracking Example: big beaks were good for cracking nutsnutsLong and slender beaks can be used to eat out Long and slender beaks can be used to eat out of flowersof flowersShort and wide beaks are for eating insectsShort and wide beaks are for eating insectsShort and stubby beaks are great for seeds Short and stubby beaks are great for seeds

Natural SelectionNatural Selection
Natural selectionNatural selectionNatural selection: when an animal adapts to his Natural selection: when an animal adapts to his environment depending on what part of the world environment depending on what part of the world where they exist and to reproduce and pass on where they exist and to reproduce and pass on genes.genes.
Natural selection relates to evolution because on Natural selection relates to evolution because on evolution the animals change so they could evolution the animals change so they could survive just like on natural selection. survive just like on natural selection.
MutationMutation
Mutation is when the DNA is damage. Mutation is when the DNA is damage.
Mutation- a mutation can be that one animal is Mutation- a mutation can be that one animal is bigger then the rest of it species.bigger then the rest of it species.
Mutation is related to genetic diversity because Mutation is related to genetic diversity because a mutation can be passed down as a trait or a mutation can be passed down as a trait or gene of the parent. gene of the parent.
VariationVariation
Variations is in all of the population of living Variations is in all of the population of living things. For example fish are the same spice but things. For example fish are the same spice but they look different on sizes and colors.they look different on sizes and colors.
One spice can survive because of the color and One spice can survive because of the color and pass on the genes and the other one could go pass on the genes and the other one could go extinct. That’s how population could improve extinct. That’s how population could improve if there are changes in the environment. if there are changes in the environment.
VariationVariation
Is when there’s more then one kind of species Is when there’s more then one kind of species in a population, That is different then the rest.in a population, That is different then the rest.
Ex: moth that looks like a leaf so I could Ex: moth that looks like a leaf so I could survive and can pass on the genes.survive and can pass on the genes.
Natural selection is competition for food space mates Natural selection is competition for food space mates etc. struggle to survive because they are batter etc. struggle to survive because they are batter equipped they pass on their genes and their traits. equipped they pass on their genes and their traits.
How do species change or vary from each other How do species change or vary from each other caused by DNA in 2 wayscaused by DNA in 2 ways

PopulationPopulation
Population- the changes in the population are Population- the changes in the population are dependent on the species attraction to one dependent on the species attraction to one another. another.
Population can change because of genetic Population can change because of genetic diversity. It can change because an animal can diversity. It can change because an animal can mate with a different animal and create a new mate with a different animal and create a new species. species.
AdaptationAdaptation
adaptation- change in the anatomy that helps adaptation- change in the anatomy that helps an organism survive better. one of the biggest an organism survive better. one of the biggest problems with the fossil record in that is that problems with the fossil record in that is that its incomplete. Mammals show up in the fossil its incomplete. Mammals show up in the fossil record after the dinosaurs go extinct. record after the dinosaurs go extinct.
Evidence of EvolutionEvidence of Evolution

Evidence of EvolutionEvidence of Evolution
Fossils are a evidence because they let us compare
and contrast the species from the
past and form the species
