Vocabulary
These master regulatory genes determine where body parts develop in an organism.
What are hox (homeotic) genes?
The order of the development events of early life on earth in order.
What is abiotic synthesis of organic molecules, formation of macromolecules, protocell formation, and self-replication?
The order of the following events from the most recent to the most distant.
What is A, C, E, F, D, B?
This process, often following mass extinctions, leads to the rapid diversification of new groups.
What is adaptive radiation?
This extinction event led to the disappearance of non-avian dinosaurs and was triggered by a massive asteroid impact.
What is the Cretaceous mass extinction?
This term describes a self-organized collection of lipids that may have been precursors to cells.
What are protocells?
This molecule can self-replicate and display similar behavior to enzymes.
What is self-replicating RNA?
The first evidence of predator and prey interactions.
What is the Cambrian explosion?
When continents move toward or away from the equator, organisms must adapt, migrate, or face extinction due to changes in this.
What is climate change?
This mass extinction, caused by extreme volcanic activity and global warming, killed about 96% of marine species.
What is the Permian mass extinction?
This layered rock structure formed by prokaryotes is the oldest known fossil evidence of life.
What are stromatolites?
These deep-sea environments with high pH and warm temperatures may have supported the origin of life.
What are alkaline hydrothermal vents?
About 500 million years ago, these three major groups began moving onto land, forever changing Earth’s ecosystems.
What are fungi, plants, and animals?
This theory explains how Earth’s crust is broken into plates that move over the mantle.
What are plate tectonics?
Wiped out nearly 80% of species and allowed dinosaurs to become the dominant land animals.
What is the Jurassic mass extinction?
This evolutionary developmental mechanism alters the relative timing of reproductive and nonreproductive development.
What is heterochrony?
This experiment demonstrated that amino acids could form under simulated early Earth volcanic conditions.
What is the Miller's experiment?
The order of the geologic eras, from most ancient to most recent.
What is the Paleozoic, Mesozoic, Cenozoic geologic area?
When a supercontinent like Pangaea breaks apart, this geographic isolation can lead to the formation of new species.
What is allopatric speciation?
Major sea level drops during this extinction were caused by global cooling and this climate condition, thus 85% of marine species were lost.
What is the Ordovician mass extinction?
This evolutionary result occurs when sexually mature adults retain juvenile characteristics, as seen in some salamanders.
What is paedomorphosis?
The order of endosymbiosis that gave rise to the first eukaryotes.
What is ancestral anaerobic prokaryote engulfs an aerobic heterotroph prokaryote and then engulfs a photosynthetic prokaryote?
This major atmospheric change, caused by photosynthetic prokaryotes, led to the extinction of many anaerobic organisms and the rise of cellular respiration.
What is the oxygen revolution?
The long-term rise and fall of major groups of organisms in the fossil record depends primarily on the balance between these two evolutionary rates.
What are speciation rates and extinction rates?
Happened in multiple pulses and devastated reef-building organisms and many marine species, dramatically reshaping ocean ecosystems.
What is the Devonian mass extinction?
