Term
Definition
7 characteristics of life   made of cells, ordered complexity, respond to external stimuli, adapted to their environment, use energy, grow and reproduce, maintain homeostasis  
🗑
5 causes of evolutionary change   natural selection, non-random mating, gene flow, genetic drift, mutation  
🗑
Hardy-Weinberg Equations   p+q=1 p^2+2pq+q^2=1  
🗑
Biology   study of life  
🗑
levels of organization   cellular, tissue, organ, organ system, organism, population, community, ecosystem, biosphere  
🗑
domains of life   Eukarya, Archaea, Bacteria  
🗑
Jean Baptise-Lamark   evolution came from traits acquired over an organisms life  
🗑
types of comparative anatomy   homologous, analogous, vestigial  
🗑
homologous   different function but came from the same body part on the same ancestor  
🗑
analogous   similar function but come from different sources  
🗑
vestigial   leftovers from ancestral needs  
🗑
genome   all the genetic information of an organism  
🗑
proteome   all the genetic information of an organism which codes for a protein  
🗑
gene   information which codes for a single protein  
🗑
gene pool   all the possible alleles for a certain gene within a population  
🗑
allele   possible option for a gene  
🗑
gene flow   the passage of genes in and out of a population due to immigration and emigration  
🗑
genetic drift   large changes to the gene pool of a population due to small population size (often due to chance)  
🗑
evolutionary fitness   an organisms ability to successfully reproduce and pass on its genetic information to offspring  
🗑
phenotype   the physical expression of an organism's genes  
🗑
vertical evoltuion   the passage of genetic information from generation to generation  
🗑
horizontal evolution   the passage of genetic information within a generation  
🗑
biological species concept   a species is a group which can interbreed and produce viable offspring. Speciation occurs whenever two populations become reproductively isolated  
🗑
allopatric separation   separated geographically  
🗑
sympatric speciation   distinct species within one environment  
🗑
gradualism   evolutionary change happens slowly over millions of years  
🗑
punctuated equilibrium   long periods of evolutionary stagnation followed by periods of intense evolution  
🗑
phylogenetic species concept   species are groups of populations that have been evolving independently of other groups of populations. Looks at whether there are shared derived characteristics  
🗑
types of reproductive isolation   behavioral, temporal, mechanical, gametic, ecological  
🗑
cell theory   all living things are made of cells, cells come from other cells  
🗑
behavioral isolation   mating rituals  
🗑
temporal isolation   different mating seasons  
🗑
mechanical   it doesn't fit  
🗑
gametic   the gamete cannot form  
🗑
ecological   they occupy different parts of their environments and so rarely interact  
🗑
adaptive radiation   whenever a new environment with ample resources and low competition occurs, a species may evolve into many similar species, each well adapted to their environment  
🗑
major categories of domain eukarya   plants, fungi, protists, animals  
🗑
types of evolution   directional, stabilizing, disruptive  
🗑
stabilizing evolution   favors the intermediate and eliminates the extremes  
🗑
disruptive evoltuion   favors the extremes and eliminates the intermediates  
🗑
directional evolution   favors one extreme  
🗑
ecosystem   the biological community and the surrounding environment  
🗑
biological community   all the populations in an environment  
🗑
polypoloidy   having three or more sets of chromosomes  
🗑
Jean Baptise-Lamark's theory   acquired trait inheritance  
🗑


   

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.
