This takes place when humans decide which organisms will breed.
What is artificial selection?

These differences exist in a population.
What are variation in traits?

These molecules control what the cell does.
What is genetic material/DNA/RNA?
200
A set of species that have a common ancestor.
What is a clade?

From his voyage on the HMS Beagle Darwin took samples of these back to England for analysis.
What plants, animals and fossils?

What is favourable/advantageous?
200
The creating of offspring.
What is reproduction?
300
Traits that are shared by some species and not others that are used to determine evolutionary relationships.
What are derived traits?

Darwin noticed significant differences between these that he observed during his voyage with a climate similar to his homeland and those from his homeland.
What are plants & animals?
300
The geologist who proposed that geographical changes occur over long periods of time. Darwin came to the conclusion that these slow changes would slowly affect the organisms living in that area.
Who is Charles Lyell?

Lack of resources will result in this happening to some of the offspring.
What is death?

What is pass their traits onto their offspring?
400
Organisms use this to grow and develop.
What is energy?

Darwin gathered these during his time in the Galapagos islands and they led him to the conclusion that new species can evolve from existing species.
What are observations and evidence?
500
Over great periods of time populations change due to an accumulation of these.
What are small changes?

An example of this is a person pulling their hand upon touching a hot stove.
