|
Definition
1) Genetics
2) Systematicists |
|
|
Term
The comparison of __________ sequences is now the primary basis for determining evolutionary relationships between organisms. |
|
Definition
|
|
Term

|
Definition
|
|
Term
A __________ is the basic unit of classification. |
|
Definition
|
|
Term

|
Definition
|
|
Term

|
Definition
|
|
Term
__________ __________ was the first to develop the biological species concept. |
|
Definition
|
|
Term
Ernst Mayr acquired the idea of the biological species concept through studying a vast variety of __________ in __________ __________ in the 1920s. |
|
Definition
|
|
Term
The __________ __________ __________ is when a species consists of a group of populations whose members are potentially capable of interbreeding in nature to produce offsrping. |
|
Definition
1) Biological species concept |
|
|
Term
The three limitations to the biological species concept are: |
|
Definition
1. Some organisms reproduce asexually 2. Doesn't help classify extinct species 3. Doesn't work well with prokaryotes |
|
|
Term
The __________ __________ __________ is the idea that organisms that look the same are considered to be in the same species; initially implied to body morphology. |
|
Definition
1) Morphological species concept |
|
|
Term
The morphological species concept is more flexible than the biological species concept for two primary reasons: |
|
Definition
1) Allows classification of extinct species 2) A biological species is likely to fit the morphospecies concept because organisms sharing a common gene pool are very likely to look similar. |
|
|
Term
The __________ __________ __________ allows for the classification of extinct species. |
|
Definition
1) Morphological species concept |
|
|
Term
The __________ __________ __________ is more likely to fit the __________ __________ __________ because organisms sharing a common gene pool are very likely to look similar as genes determine morphology. |
|
Definition
1) Biological species concept 2) Morphological species concept |
|
|

|
Definition
|
|
Term

|
Definition
|
|
Term
