Across
- 3. Groups of interbreeding populations capable of producing offspring
- 4. Process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.
- 9. makes up about 90% of earth's history; 4.6billion-540million years ago; single celled organisms, earth crust forms, creation of atmosphere, very late period has multicellular organisms
- 10. Physical expressions of genetic traits (observable characteristics)
- 12. 252mill-66mill years ago, the rise of dinosaurs, separation of Pangea, mammals (beginning), flowering plants and conifers
- 14. Groups of organisms living in the same area
- 17. Structures in different species that are similar because of common ancestry.
- 18. Remnants of organs/structures that had a function in an early ancestor
- 21. Variation in parent genes being passed through genetics
- 22. Specific characteristics of an individual, passed from parents DNA to offspring
- 24. 66mill-Present years ago, the rise of mammals, humans, grasslands, agriculture, cities, ice age and glaciation.
- 26. Principle that each living species has descended, with changes, from other species over time
- 28. Selective breeding of organisms by humans for specific characteristics
- 29. process of measuring the absolute age of geologic material by measuring the concentrations of radioactive isotopes and their decay
Down
- 1. Name of the island Charles Darwin discovered Finches upon. It’s off the coast of Ecuador.
- 2. Categories of time into which Earth's history is divided by geologists and paleontologists
- 5. Uses physical properties of specimen to assign year range for specimens, uses radioactive isotopes for dating
- 6. Places various geologic events in sequential order, uses rock formations/orders of layers to make determination
- 7. organisms change and develop over time to increase rate of survival
- 8. 540mill-252mill years ago; the rise of fish -> amphibians -> reptiles, first land plants, continental movement
- 11. One of the men who discovered evolution, published the book On the Origin of Species.
- 13. Study of embryos and their development
- 15. Structures that do not have a common evolutionary origin but are similar in function
- 16. One of the men who discovered evolution, published the book the Malay Archipelago
- 19. Age of Earth
- 20. The top rock layer and its fossils is the youngest and the bottom is the oldest
- 23. Geographic distribution of animals.
- 25. Chronological collection of life's remains in sedimentary rock layers
- 27. The line through Malaysia that divides the animals of New Guinea and Australia from Indonesia and Asia.
