The primary difference natural and artificial selection is
In nature selection the “pressure” comes from the environment; In artificial selection the “pressure” comes from humans (or another species).
In artificial selection the “pressure” comes from the environment; In natural selection the “pressure” comes from humans (or another species).
Natural selections is when humans breed the animal; Artificial selection is when humans direct genes directly.
They are different terms for the same concept.

How has technology helped us in understanding evolutionary relationships?
We can travel back in time to observe different organisms in their habitats.
We clone different organisms using DNA from fossils so we can bring them back and observe.
We can now compare the DNA of different organisms to help determine the relationships between them.
We can follow different organisms on Twitter to look for similar traits and characteristics.
How can a cladogram be used to show how closely related two organisms are?
The further apart two organisms are on a cladogram the more they have in common.
If two organisms are next to each other on a cladogram then they must be the same species.
All organisms share a common ancestor.
You can use a cladogram to see how many traits two organisms have in common. The more in common, the more closely related they are.
