What Connects Species?
This post will go through relationships between species for QCE Biology.
4.2.1 – Evolution
- Interpret data (i.e. degree of DNA similarity) to reveal phylogenetic relationships with an understanding that comparative genomics involves the comparison of genomic features to provide evidence for the theory of
Evolution and Species
Over many generations, depending on their environment, a species may adapt differently (divergent evolution) producing two or more different species. Alternatively, if two different species adapt to similar environments, they may end up having similar traits (convergent evolution) for example whales and dolphins.
This video will go through some evolutionary relationships.
This video will go through understanding these evolutionary relationships.
Evidence for These Relationships
We can compare the evolution of species by analysing their genomic information. This video will go through comparative genomics.
This video will go through some methods used to assess evolutionary relationships in a little more detail.
This video will go through comparative anatomy (which is the comparison of similar physical features).
