Lesson 1
The scientific theory that states, "organisms change over time" was introduced by
Who is Darwin
This occurs when humans breed animals for specific traits
What is artificial selection
What is coevolution
This is when a species no longer exist and will never live again on earth.
What is extinct
This is the name for the last universal common ancestor
What is LUCA
This theory states that organism gradually change over time.
What is evolution
This occurs when species with desired traits survive and reproduce together
What is natural selection
This is the process where two different species interact over time and evolve in response
What is coevolution
These are two reasons for extinction
What is new predators, climate change, disease, and new competition.
This evidence shows that all organisms on earth once had a common ancestor
What is all organisms use DNA for genetic material
These are the types of birds that Darwin saw with different variations
What is a finch
This is the struggle among living things to get the required food, water, and shelter
What is competition
A seed gets stuck to an animals fur and is transported into a new population. This is an example of
What is Gene flow
Preserved Turtle droppings are an example of
What is a trace fossil.
This is when one organism moves inside another organisms cell
What is endosymbiois
This is how we date things within rock layers
What is Old rocks are at the bottom, young rocks are at the top.
This occurs when an error happens when the DNA is coding, it can be good, bad or neutral
What is mutation
The last two yellow snakes in a population are ran over by a truck. This is an example of
What is genetic Drift.
Sheep developing curly wool is an example of
What is micro evolution
This element is not found in protiens
What is sodium
Preserved remains or traces of an organism from the past
What are fossils
These are the three factors of natural selection according to darwin
What are variation, overproduction, and competition.
These are the two abilities that impact an organism's fitness the most
What is ability to survive, and the ability to reproduce
Single cell organisms developing into fish is an example of
What is macroevolution
These two cell parts are believed to have evolved through endosymbiosis
What are the chloroplast and mitochondria
