Evolution Crossword

pertain to the various structures in different species having the same function but have evolved separately, thus do not share common ancestor
any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences or by the effect of environmental factors on the expression of the genetic potentials
a particular section, group, or type of people or animals living in an area or country.
a phrase that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection.
the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock.
it's when very different animals have bones that appear very similar in form or function and seem to be related.
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.
the theory that changes in the earth's crust during geological history have resulted chiefly from sudden violent and unusual events
the formation of new and distinct species in the course of evolution.
The breeding of plants and animals to produce desirable traits. Organisms with the desired traits, such as size or taste, are artificially mated or cross-pollinated with organisms with similar desired traits.
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.
the hypothesis that evolutionary development is marked by isolated episodes of rapid specialization between long periods of little or no change.
the diversification of a group of organisms into forms filling different ecological niches.
function of an organism or any of its parts that results from natural selection and by which the organism becomes better fitted to survive and multiply in its environment.
the hypothesis that evolution proceeds chiefly by the accumulation of gradual changes
relativethe genetic contribution of an individual to the next generation's gene pool to the average for the population, usually measured by the number of offspring or close kin that survive to reproductive age
A structure in an organism that has lost all or most of its original function in the course of evolution, such as human appendixes.
the termination of an organism or of a group of organisms normally a species.
the proportion of this total variation between individuals in a given population due to genetic variation
the Earth's crust have acted in the same the fundamental principle or doctrine that geologic processes and natural laws now operating to modify the regular manner and with essentially the same intensity throughout geologic time, and that past
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
