|
Out gassing-
|
elease or give off (a substance) as a gas or vapor.
|
|
|
Paleontologist
|
A paleontologist is a scientist who studies fossils. If your basement is filled with fossils found while out on hikes, then you're an amateur paleontologist.
|
|
|
LUCA
|
Last Universal Common Ancestor,
|
|
|
metabolism |
Metabolism is a term that is used to describe all chemical reactions involved in maintaining the living state of the cells and the organism.
|
|
|
microbe
|
a microorganism, especially a bacterium causing disease or fermentation.
|
|
|
Microcontinent
|
an isolated fragment of continental crust forming part of a small crust plate.
|
|
|
Nucleic Acid |
complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain. |
|
|
Stromatolites |
The oldest fossils on earth |
|
|
Supercontinent |
In geology, a supercontinent is the assembly of most or all of Earth's continental blocks or cratons to form a single large landmass.However, the definition of a supercontinent can be ambiguous |
|
|
Symbiotic
|
In biology, symbiotic refers to any diverse organisms that live together, but in this case, the relationship is not necessarily beneficial to both.
|
|
|
Craton |
A large, stable block of the earth's crust forming the nucleus of a continent. |
|
|
Cyanobacteria |
is a phylum of bacteria that obtain their energy through photosynthesis. The name "cyanobacteria" comes from the color of the bacteria. |
|
|
Eukaryote |
is any organism whose cells contain a nucleus and other organelles enclosed within membranes. |
|
|
Greenstone
|
a greenish igneous rock containing feldspar and hornblende.
|
|
|
Paleogeography
|
the study of geographical features at particular times in the geological past.
|
|
|
Photosynthesis |
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities (energy transformation). |
|
|
Prokaryote |
a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles.
|
|
|
RNA world hypothesis |
according to the RNA World Hypothesis, life later evolved to use DNA and proteins due to RNA's relative instability and poorer catalytic properties, and gradually, ribozymes became increasingly phased out. |
|
|
Evolution |
the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth. |
|
|
Mutation |
the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. |
|
|
Natural selection |
the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution. |
|
|
Orogeny |
a process in which a section of the earth's crust is folded and deformed by lateral compression to form a mountain range. |
|
|
Marine Regression |
Marine regression is a geological process occurring when areas of submerged seafloor are exposed above the sea level. The opposite event, marine transgression, occurs when flooding from the sea covers previously exposed land |
|
|
Variation |
a change or difference in condition, amount, or level, typically with certain limits. |
|
|
Adaptive Radiation |
- the diversification of a group of organisms into forms filling different ecological niches. |
