| The second possible mechanism is acceleration or retardation of development in the course of phyletic evolution. |
|
| Colored lines connect histidine kinase and response regulator proteins belonging to the same signaling pathway or species phyletic cluster. |
|
| The phyletic lines of many animal groups, for instance, show examples of extinct ancestors that grew increasingly large until they died off. |
|
| They argue that phyletic evolution that is, evolution along lineages of descent proceeds at two levels. |
|
| The phyletic relationship of the chimaeras and the sharks and rays is a subject open to varying interpretation. |
|
| For the purpose of calculating community similarity, species that are part of possible phyletic sequences were synonymized to correct for pseudoextinction. |
|
| Firstly, to contribute to advancing knowledge concerning the identity of the taxa and their phyletic relationships. |
|
| This similarity presumably relates more to size reduction in the two genera rather than phyletic relationship. |
|
| It's phyletic gradualism versus punctuated equilibrium. |
|
| However, venation patterns must be considered in terms of the evolution of these patterns from primitive to advanced conditions within individual phyletic lines. |
|
| Classifications are a reflection of all aspects of evolutionary change, not simply phyletic splitting. |
