Explain why we are still piecing together a picture of how human evolution occurred, and how is it possible that our understanding of it might be flawed?
What are three advantages of using scientific names for organisms?
1) Some of the fossils we would need to link humans to previous species are too old to carbon date. Also, we have only found fossils of some of the species involved in our evolution. Even if the DNA is similar, it is impossile to say whether that particular species evolved into humans today.
2) *Scientific names are universal, meaning everone calls a specific species by a specific name, prevents confusion.
*Using scientific names, you can see the relationships between organsism, meaning if they are in the same genus, you know they are related.
*I can't think of a third, sorry... there's gotta be tons of reasons
1.) We do not have exact linkages between animals, and therefore we have to guess at a chronicological order that bests fits the data. It could be flawed because certain features of one animal could have rose independtly of other animal and we can inadvertantly link them together.
2.) Advantages:
- Universal Code allows identification across language barriers.
- Demostrates relationships between animals
- Can be descriptive (i.e megalotis means "big ears")
- Can sometimes tell you who discovered the animal (i.e. Myotis Keenii meaning Keen's mouse-eared bat)
- They can reflect the common name given to an animal by it's native peoples (i.e Oncifelis guigna which is a American small cat species refered to as guigna in Chile and Argentina)
