Across
- 5. Described cycles that change earth’s orbit, tilt and wobbling
- 9. Tendency of Earth's biota to be organized into distinct, geographically bounded regions (provinces) characterized by unique species assemblages and high levels of endemism
- 11. Large ice sheet that cover most of Canada and the Northern United States 20000 years ago
- 12. Tree genus that has a southern distribution, New Guinea, New Caledonia, Australia, New Zealand, Antarctica and South America
- 16. Integration of population genetics, phylogenetics, and historical geography to map genetic variations over space and time
- 18. This bird cannot carry a 1-pound coconut to Mercia
- 22. Movement of individuals, propagules (seeds, spores), or populations away from their birth site or origin to new locations
- 27. Index fossil found in chalk
- 28. German geographer, one oceanic current named after him flows along the western coast of South America
- 29. Death of a taxon
- 30. Local variety of a species whose appearance, behavior, and structural habitat (niche) are shaped by its environment
- 31. Endemic bird to South America that has claws in their wings
- 32. The spatial spread of organisms from a point of origin to new areas, representing a key mechanism for range expansion. It is a gradual, continuous dispersal process where a population expands outward from a core area into adjacent, unoccupied habitats, different from "jump dispersal," which involves long-distance
Down
- 1. The point in a planet's orbit when it is farthest from the sun
- 2. Biological classification method that reconstructs evolutionary relationships (phylogeny) by grouping organisms into clades based on shared derived characteristics (synapomorphies)
- 3. The principal natural taxonomic unit, ranking below a genus
- 4. Preserved remains, impression, or trace of any once-living organism from a past geological age
- 6. Indigenous, native
- 7. This word is used to describe a mechanism of evolution and movements of continents
- 8. Massive, slow-moving rivers of ice and compressed snow that form on land over centuries
- 10. Geological epoch that lasted from around 2.58 million to 11,700 years ago
- 13. When life nearly died
- 14. Two or more lineages originate from a common ancestor
- 15. A unique biogeographical transition zone in central Indonesia, separated from Asian and Australian continental shelves by deep-water strait
- 17. the geographical separation of a population into isolated subpopulations by new physical barriers
- 19. Distinctive, derived trait that is unique to a single terminal taxon not very useful to build trees
- 20. Equal day and night lengths
- 21. Hypothetical protoplanet that collided with the ancestral earth and might have formed the moon
- 23. Type of zone frequently found in the pacific ring of fire
- 24. the movement of people or animals from one place of residence or habitat to another, often over long distances
- 25. Informal nickname of the person that proposed evolutionary theory
- 26. Words in different languages related by a common ancestor, often sharing similar spellings
