Limited resources contribute to evolutionary change in animals by increasing A) genetic variation within the population B) competetion between members of the species C) the carrying cappacity for the species D) the rate of reproduction in the population

Over many generations unrelated or distantly relatd species may come to resemble one another due to: A) homologous structure adaptation B) Similar enviromental factors C) competetion with each other D) similar genetic mutations

Theory of evolution based on the inheritance of aquired characteristics was proposed by: A) Darwon B) Malthaus C) Lamrack D) Oparin

Which is a major concept included in Lamracks theory of evolution? A) Change is the reslut of survival of the fittest B) Body structure can change according to the actions of the organism C) Population size decreases the rate of evolution D) Artificial selection is the basis for revolution
