|
The species concept
Plants and Animals |

|
The Species concept
Microorganisms |
most reproduce asexually therefore the species concept is more arbituary and phenetic and based on observable characteristics
|
|
|
Numerical taxonomy
|
strictly phenetic- numbers are assigned to particular characteristics and all these numbers are put into a computer program and then MO are grouped strictly on the total number of similarities and diffrences NO ONE CHARACTERISTIC HAS MORE WEIGHT THAN ANOTHER
