🗑
|
||||
| Analogous structure | show 🗑
|
||||
| Example of analogous structure | show 🗑
|
||||

🗑
|
||||
| show | similar structures from dissimilar descent (ex. flippers on penguins, dolphins, and sharks)
🗑
|
||||
| show | common ancestry is the primary criterion used to classify organisms (used to infer phylogeny from homologous structures)
🗑
|
||||

|
||||
| Polyphyletic group | show 🗑

|
||||
| show | derived
🗑
|

| show | Species/group of species that is known to have diverged before the lineage of a selected ingroup
🗑
|
||||
| show | The group you are studying
🗑
|

|
||||
| True or false: Some diagrams have branch lengths that attempt to indicate a proportional amount of evolutionary change or times for particular events | show 🗑
|
||||
| What are two things branch lines could possibly indicate on a phylogenetic tree? | show 🗑
|
||||
| How do systematics narrow down the possibilities for possible phylogenetic trees? | show 🗑
|
||||
| show | The simplest explanation that is consistent with the facts (For trees based on morphology, fewest evolutionary events. For trees based on DNA, fewest base changes)
🗑
|
||||
| show | Tree most likely to have produced a given set of DNA data based on certain probability rules about how DNA sequences change
🗑
|
||||
| show | Features shared by two groups of closely related organisms are present in their common ancestor and all of its descendants
🗑
|
||||
| show | Help track evolutionary time
🗑
|
||||
| Molecular clocks | show 🗑
|
||||
| show | The homology of species is a result from a speciation event
🗑
|
||||
| Paralogous genes | show 🗑
|
||||
| show | 1. The number of nucleotide substitution in orthologous genes is proportional to the time that has elapsed since the genes branched from ancestry
🗑
|
||||
| show | Some genes may evolve in irregular bursts, some genes have random deviations from an otherwise "smooth" average, the same gene may evolve at different rates in different groups of organisms, the rate of the clock may vary from one gene to another
🗑
