| A stabilized polygenetic result of crossing a very hight quality two-way genetics. |
| Antithetically, where more common polygenetic morphogenesis occurs, some mixture of tectonic, marine, or climatic effects is superimposed on the setting, and a hybrid suite of landforms results. |
| The core material preserves diverse structures testifying to its polygenetic origin and an evolution from a hydrostatic to a tectonic stress-dominated environment. |
| This condition makes it appear quite possible that the family may be polygenetic. |
| One estimate places polygenetic landforms over approximately 80 percent of the Earth's land surface. |
| Paleocene and Eocene sediments were deposited on a polygenetic sub-Paleogene surface. |
