🗑
|
||||
| show | Is the slow change of a species over time
🗑
|
||||
| show | Is the slow change of Earth over time
🗑
|
||||
| show | In different organisms, have similar internal structures or embryonic development
🗑
|
||||

🗑
|

| CLUES ON EARTH PROVIDE EVIDENCE OF EVOLUTION | show 🗑
|
||||
| VESTIGIAL STRUCTURES | show 🗑
|
||||
| FOSSIL | show 🗑
|
||||
| show | A hard, yellow, transparent material formed by the hardening of resin, a sticky substance produced by trees.
🗑
|
||||
| show | Wooly Mammoth & furry rhinoceros have been found with flesh, skin and hair.
🗑
|
||||
| PETRIFICATION | show 🗑
|
||||
| BONES | show 🗑
|
||||
| MOLDS | show 🗑
|
||||
| show | Form when the molds fill with minerals and harden to form rock; a copy of the organism forms.
🗑
|
||||
| show | The impressions made in mud and then hardens into rock (Ex: animal footprints & leaves)
🗑
|
||||
| show | Relative dating & Absolute dating
🗑
|
||||
| RELATIVE DATING | show 🗑
|
||||
| show | Top layer of sedimentary rock
🗑
|
||||
| show | Bottom layer of sedimentary rock
🗑
|
||||
| show | Any method that determines how long ago an event occurred. (Ex: Radioactive dating)
🗑
|
||||
| show | Measures radioactivity decay in an isotope (Ex: C-14 - 5,370 years, U-238 - 4.5 billion years & K-40 - 1.3 billing years)
🗑
|
||||
| show | A type of rock formed from layers of particles that settled to the bottom of a body of water, often containing fossils
🗑
|
||||
| show | The history of life as determined by the relative age of fossils
🗑
|
||||
| show | Formed when molten material in the crust cooled and hardened. Can be dated using radioactive dating methods.
🗑
|
||||
| CORRELATION | show 🗑
|
||||
| show | Fossils that permit the relative dating of rocks within a narrow time span.
🗑
|
||||
| show | A timetable of the earth's history constructed by geologists
🗑
|
||||
| show | The end of a species when the last individual of that species has died
🗑
|
||||
| FROM ROCKS AND FOSSILS | show 🗑
|
||||
| EVIDENCE FROM COMPARATIVE CYTOLOGY | show 🗑
|
||||
| show | Physiology, biochemistry, cytochrome c in humans & chimpanzees is same, but differs in bread mold, & insulin from sheep & pigs is same for humans.
🗑
|
||||
| show | How organisms function
🗑
|
||||
| BIOCHEMISTRY | show 🗑
|
||||
| COMPARATIVE ANATOMY OR HOMOLOGOUS STRUCTURE | show 🗑
|
||||
| show | Same function but different origin and structure (ex: wings of fly (has membranes) vs. bird (has bones)...Both used to fly.
🗑
|
||||
| show | Antibody reactions to protein or viruses may act the same.
🗑
|
||||
| show | All embryos look similar at first and then differentiate and evolve.
🗑
|
||||
| show | Structures that remain but have no function (ex: Coccyx - fused bone (tail))
🗑
|
||||
| SPONTANEOUS GENERATION | show 🗑
|
||||
| BIOGENESIS | show 🗑
|
||||
| show | The hypothesis that the first organic compounds were formed by natural chemical processes on the primitive earth and that the first lifelike structures developed from coacervates and were heterotrophs.
🗑
|
||||
| show | According to the heterotroph hypothesis, an aggregate of large protein like molecules; thought to have developed into the first forms of life on the primitive earth.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
