Why do you scientists use evolutionarily trees
To show how closely related organisms are to each other
How can scientists make evolutionary trees
By using classification data on living organisms eg dna
However for extinct organisms scientists have to use fossils which presents a problem as the fossil record of many species are incomplete
How can you see a common ancestor in a evolutionary tree
Where the lines intersect
