What are hydrogen cyanide, hydrogen sulfide, carbon monoxide, and carbon dioxide. May have water and nitrogen.

Formation of new species
What is speciation?
100
Source of genetic variability; any change in DNA or sexual reproduction
What is mutation and/or gene shuffling?
100
In a population of lizards, the smallest and largest lizards are more easily preyed upon than middle-sized lizards. This is the kind of natural selection that is MOST LIKELY to occur in this situation.
What is stabilizing selection?
200
Evolutionary process that produces a similar appearance among unrelated groups of organisms such as sharks and whales having similar body structures
What is convergent evolution?
200
K-T boundary shows this
What is the line in the rocks/earthen strata that separates period of dinosaurs and mass extinction of dinosaurs?
200
Isolating mechanism occurs when two or more species reproduce at different times...three similar species of orchid all live in the rain forest and each releases pollen only on a single day, and therefore, they can not pollinate one another. (page 405)
What is temporal isolation?
200
Number of times alleles occur in a gene pool
What is relative frequency or allele frequency?
200
Bird's wings are "matches" to dog's front legs
What is homologous structures?
300
Large scale evolutionary changes that take place over long periods of time: examples include extinction, adaptive radiation, coevolution, convergent evolution, developmental hox genes, and punctuated equilibrium.
What is macroevolution?
300
The Age of Mammals
What is the Cenozoic Era?
300
Evolution of several hundred species of fruit flies found on different Hawaiian Islands that descended from the same original mainland populations is an example.
What is the founder effect? Genetic Drift?
300
Change in allele frequency that results from the migration of a small subgroup of a population
What is the founder effect?
300
Inheritance of acquired traits; use it or loose it...Scientist
Who is Lamarck?
400
Theory that states eukaryotic cells arose from living communities formed by prokaryotic cells and specifically prokaryotes evolved to form both chloroplasts and mitochondria.
What is endosymbiotic theory?
400
The Age of Dinosaurs (Reptiles)
What is the Mesozoic Era?
400
Type of population evolution when individuals at one end of the curve have higher fitness than individuals in the middle of at the other end.
What is directional selection?
400
The evolution of Darwin's finches is an example of this
What is adaptive radiation and/or speciation?
400
Scientists who formed theory of evolution through natural selection.
Who is Charles Darwin?
500
Four eras of Geologic Time Scale in order of occurence.
What are Precambrian, Paleozoic, Mesozoic, and Cenozoic?
500
Miller and Urey's experiments suggested how mixtures of the Earth's early gases formed these specific types of molecules.
What are amino acids and organic compounds.
500
Type of situation in which individuals near the center of the curve have higher fitness than individuals at either end of the curve.
What is stabilization selection?
500
The success of an organism in surviving and reproducing is a measure of this.
What is fitness?
500
Large ground finch obtains food by cracking seeds; its short beak is an example of this.
