Down: 1) The view that evolution proceeds by imperceptibly small, cumulative steps over long period of time rather than by abrupt, major changes.2) A diagram beginning with a common ancestor, shows the evolutionary history of a species.3) The hypothesis that evolutionary development is marked by isolated episodes of rapid speciation between long period of little to no change.6) A multi-step tool used to identify a species based on physical characteristics it may possess.11) A term that refers to a population of animals, plants, or other organisms that are separated from exchanging genetic material with other organisms of the same species.14) A biological preparation that improves immunity to a particular disease which contains an agent that resembles a disease causing microorganism, and is often made from weakened or killed forms of the microbe.18) Occurs when two or more populations evolve at the same time.24) Non-living pathogen that causes many harmful condition, vaccines protect against them. Across: 3) An organism's defense against invading pathogens due to the transfer of antibodies: example baby receiving breast milk.4) A diagram beginning with an outgrip organism, shows relationships based on shared derived traits.5) The situation where different species may live in the same area, but properties of individuals prevent them from interbreeding.7) Genus of bacteria, commonly know for causing strep throat.8) Nature favors one extreme phenotype in a population. Example: finch beak size during different seasons.9) The theory that living organism can come from non-living matter.10) Nature favors one extreme phenotype in a population; example: average baby weight.12) Explains how smaller prokaryotes were consumed by larger prokaryotes, evolving into organelles such a the mitochondria and chloroplasts to create eukaryotic cells; mitochondria contains its own DNA as evidence to support this.13) Occurs when different species develop similar traits for similar functions: Examples: fish, dolphin, penguin15) Nature favors both extreme phenotypes in a population: example: clam shell color against the environment.16) The changes that occur at the molecular level in organisms over a period of time. These range from deletions, additions or substitutions of single nucleotides, through the rearrangement of parts of genes, to the duplication of entire genes or even whole genomes.17) Structures that originate from the same type of tissue but may be used differently in different organisms.19) The change in a species as a whole over time.20) The system of naming organisms based on their scientific genus and species.21) The theory that living organism can only come from other living organisms.22) System of placing organism in groups based on similarities: Domain Kingdom, Phylum, Class, Order, Family, Genus, Species23) Occurs when two species evolve to be more and more different over time. 25) The emergence of a new species due to natural selection.26) Organisms that are best suited for survival are the ones that successfully reproduce and pass on their beneficial characterisitcs, leads to evolution.27) The changes in behavior, function and structure of an organism to become more suited to an environment.28) A structure that may have once had a function in a species but has evolved to be useless over time. (Examples: appendix, whale hip bone)29) An organism's defense against invading pathogens due to the production of antibodies, example: vaccines.
