In this IBDP Biology blog post, it will include the different plant and animal phylas, and natural classification, let's go!
Plant Phylas

Animal Phyla

Natural Classification
Members of a group share homologous traits that are inherited from common ancestors
Artificial classification: Grouping birds, bats and insects together because of their ability to fly as they do not share a common ancestor
Natural Classification is not straightforward because:
- Convergent Evolution -
Make distinctly related organisms appear similar
- Adaptive Radiation -
Make similar organisms appear very different from each other
ADVANTAGES:
- Identification of a species is easier dichotomus keys can be used to help this process
- All members of a group inherit similar characteristics this allows for characteristics to be predicted. If a new species was discovered predictions could be made about it
Reviewing Classification
- Members of a group that do not share a common ancestor are split into more taxa
- If species are found to share a common ancestor the taxa is reunited
That's the end!
