Down: 1) an accidental change in gene frequency that affects small populations only, as the result of chance of natural selection3) a change on the allele frequency of a population that occurs when an environmental change isn't favorable for the most common phenotype4) the changes in populations over long periods of time; the change within the gene pool of a population5) a state of constant allele frequency of population that occurs when an environmental change favors an extreme phenotype for a trait6) a theory about the rate of evolution -- that the small genetic changes accumulate in a population over long periods of time9) Charles Darwin''s theory of a mechanism for evolution, organisms w/ traits favorable for their environment are more likely to survive, reproduce, and pass on the favorable traits to offspring12) a change on the allele frequency of a population that occurs when an environmental changes favors an extreme phenotype for a trait 14) a difference between members of the same population15) the preserved remains or imprints of ancient organisms17) an inherited biological or behavior trait that increases a population's chances for survival in a specific environment21) the combined genetic material of all the memories of a given population 22) the specific role an organism plays within it's community Across: 2) the evolution of one or more new species from a single ancestral species7) an interbreeding population of organisms that can produce healthy, fertile offspring8) a process in which once-related populations evolve independently; often occurs as the result of geographic isolation10) a structure or characteristic that's unused but which is homologous with structure or characteristic in other species, suggesting common ancestor 11) the fraction of all genes for a particular trait that each allele represents in a gene pool13) the emergence of diverse species from a common ancestor due to adaptation to many new environment16) characteristic shared by different species that's similar in function but not inherited from a common ancestor18) a process in which 2 or more populations that closely interact over an extended period of time adapt to one another19) one theory about the rate of evolution -- that the small genetic changes accumulate in a population over long periods of time20) a process in which different species evolve with similar characteristic; often the result living in a similar environment 23) a structure or characteristic with similar functions found in different species; thought to be inherited from common ancestor
