Storyboard Text
Explaining Homologous, Analogous, and Vestigial.
What is it ? Homologous structures are parts of different organisms that are similar. This is because they have a similar or common ancestor.
Examples of this can be: the wing of a bat and the leg of a cat.
Homologous
What is it ? Analogous Structures are structures that have the same movement or function but not the same structure.
An example of this is the wing of a bat and the wing of a bird. They are both used to fly but they are not built the same.
Analogous
What is it ? Vestigial Structures are parts of an organism that are there because of their ancestors, but they don't help the organism in any way.
An example of this is the appendix of the human body. It is in our body because of our ancestors but it doesn't help us!
Vestigial
Homologous :Parts of different organisms that are similar because of a shared ancestor.Example:Leg of a cat and wing of a bat
Lets Review !
Analogous :Structures of an organism that have the same function but different structure.Example:The wing of a bird and the wing of a bat.#160;
Vestigial:Parts of an organism that are there because of ancestors but they don't help the current organism.Example:The appendix of a human.
All done !Good Job !!
