Evolution is when you change heritable characteristics, or traits overtime.
History of evolution
People thought that species where not linked in a single family tree
People thought that god created everything.
Species change in order to survive.
Charles Darwin was a naturalist
He took a trip on the HMS Beagle to the Galapagos islands
Mainly studied finches and turtles
By studying these creatures he came up with the idea of natural selection
He wrote a book The Origin of Species
Darwin identified 13 species of finches
He noticed that each of the finches were different
They were all different from the size and shape of the beak
He noticed that the diet was different based on the beak.
Example: big beaks were good for cracking nuts
Long and slender beaks can be used to eat out of flowers
Short and wide beaks are for eating insects
Short and stubby beaks are great for seeds
He discovered that each of the finches beaks were different because the environment was shifting.
Natural selection was revealed
Charles Darwin The Origin of Species He study Finches, turtles and iguanas at the Galapagos islands He came up with natural selection Charles Darwin is the father of evolution He took a trip on the HMS. Alfred Wallace Convinced Charles Darwin to bring out his book called “ The Origin of Species”.
Jean Baptiste LaMarck
He was born on August 1, 1744 in Bazentin-le-Petit
He was a French soldier, naturalist, academic and an early proponent of the idea that evolution occurred.
He died on December, 18, 1829.
His theory was wrong.
Alfred Russell Wallace was born on January, 8, 1823 in Monmouthshire, Wales.
He was a was a British naturalist, explorer, geographer, anthropologist and biologist.
He also convinced Charles Darwin to bring out his book called “The Origin of Species”.
Natural selection: when an animal adapts to his environment in order to reproduce and pass on the genes.
Natural selection relates to evolution
Mutation is when the DNA is damage.
Mutation- one animal is bigger then the rest of it group.
Mutation is related to genetic diversity because a mutation can be passed down as a trait or gene of the parent.
Variations is in all of the population of living things. For example fish are the same spice but they look different on sizes and colors.
One spice can survive because of the color and pass on the genes
The other one could go extinct.
Population- the changes in a population depend on the species attraction to one another.
Population can change because of genetic diversity. It can change because an animal can mate with a different animal and create a new species.
Adaptation- a change in the structure that helps an organism to survive better.
Evidence of Evolution
Fossils: Are a trace of an organism from a past age that are skeleton or leaf imprint and conserved in the earth crust.
Fossils help scientist see the skeleton of species to tell if species have change by a period of time.
Embryology: is the study of the creation of life.
Helps scientist to learn how spices are made and how they are crated in terms of evolution.
Geographic evidence: Evidence of fossils and other different extinct animals or living forms.
That helps scientist to see how the animals looked long time ago.
Vestigial structures: Is an extra organ or a limb that is no longer use but in a time it was used by ancestors.
The whale has an extra bone that is no longer use but is was used by ancestors.
DNA is related to other species because of their ancestors
An example of this is humans and the chimpanzees have 98% of the same DNA.
Homologous structures: are body parts in many different organisms that have similar bones and similar muscles.
This helps scientists to know that we have something in common with other creatures.
Is when an animal looks like another animal like for example a moth that looks like a leaf so it could survive and pass on the genes.
Evidence of Evolution Fossils are a evidence because they let us compare and contrast the species from the past and form the species that exist now. Vestigial structures tell us how animas have change and that they have extra organs that don’t use them any more. Homologous structures tell that all of us came from a same creature.

What makes a Primate
Fingers and toes.
Hands and feet that are adapted for grasping
Eyes on front of the face with a very good vision in order to see things from a long distance.
Their face look more like the face of a human
living primates and where are they distributed
Most primates live in the tropical forest.
The smallest primates is the pygmy marmoset and it weights around 70g.
The largest primate is the gorilla and he weights about 175kg
There are about 233 living species of primates which are placed in 13 families on different places.
History of primate evolution
According to Drawing research primates mostly apes look a lot like us.
Primates evolved over time into us.
Different primate look like a human fossils like Hominids Lucy a fossil found and that came up the theory of primate evolution.
In 1859 Darwin published The Origin of the Species which become the source of the present day of theory of evolution.
The word wise in the context of human evolution, refers to the word “sapiens”
The word homo means human in Latin.
The word human in the background of human evolution, refers to the word homo .
This was chosen by a man named Carolus Linnaeus.
Genus HOMO: Is a group that includes humans and other closely related spices.
Chims and gorillas were figthing for a part of the HOMO genus, but after seeing so many differences they were not.
