Development of similar characteristics in distantly related organisms is ________________? |
Convergent evolution.
Parallel is in closely related organisms. |
|
|
Divergent evolution |
Occurs when an ancestral species gives rise to diverse descendant species |
|
|
Cladistics |
Biological analysis in which organisms are grouped together based on derived characteristics (as opposed to primitive)
Form cladogram |
|
|
Analogous structures .... |
may be superficially similar & serve some function (insect wings v bird wings) |
|
|
Vestigial structures ...... |
were once fully functional in ancestors but now only partly functional, nonfunctional, or serve a different purpose |
|
|
Difference between macro & micro-evolution? |
"micro" is change in genetic makeup (small scale change)
"macro" is changes in populations (such as a new species through classes, large scale change) |
|
|
What is an example of prediction made by evolutionary theory? |
Mammals should appear in fossil record long after fish |
|
|
In modern evolutionary theory, ___________ evolve |
populations |
|
|
Homologous structure |
similar structures even though they may serve different purposes (flying v running) |
|

Over geologic time, _________ opened up vast areas of shallow seas that could be inhabited and exploited. |
marine transgressions over cratons |
|
|
Two major plant groups? |
