What is Convergent evolution?

When 2 unrelated species adapt in the same way giving them a similar appearance

1 of 8

What is found in all respiring organisms?

Cytochrome C

2 of 8

How can Cytochrome C be used for classification evidence?

Cytochrome C isn't identical in all species, we can compare the sequence of amino acids in samples of cytochrome c from 2 different species

3 of 8

What conclusions can be drawn by comparing sequence of aminoacids in different cytochrome c's?

If the sequences are the same, the 2 species must be closely related, if the sequences are different, the 2 species are not closely related, the more differences found between the sequences the less closely related the 2 species

4 of 8

What structural differences are there between Bacteria and Archaea and Eukaryotae?

Different cell membrane structure, different enzymes for synthesising RNA and different mechanisms for DNA replication

5 of 8

What are the 2 types of classification?

Artificial and Natural

6 of 8

What is Artificial classification?

Classifying for conveniance, e.g. grouping yellow flowers and blue flowers differently. Its based on only a few characteristics and doesn't reflect evolutionary links

7 of 8

What is Natural Classification?

Involves detailed study of the individuals in a species, using many characteristics and reflects evolutionary links
