Lamarck thought that… a) A person who lifts weights and gets strong may pass this acquired trait to his offspring. b) A person who lifts weights and gets strong may NOT pass along this trait. c) A person who lifts weights and gets strong had no genetic reason for getting strong. ___________________________________________________________________________________ There are 6 main points to Darwin's theory. Match the term with the definition… Competition one trait is more favorable, so is favored Overproduction these come about from mutations and may or may not be helpful Variation over time, one species may become several Adaptations there is naturally variety among individuals in a population Selection all species tend to produce more offspring than an area can support Speciation only the species that have an advantage will thrive ____________________________________________________________________________________ The idea that evolution happens in quick (geologically speaking) bursts is called…. a) spurtism b) burstism c) puctuated equilibrium d) natural selection ____________________________________________________________________________________ There are four sources of genetic change. Match them. Mutations new genes are brought in by visiting (new) organisms Recombination when individuals get a gene combination that gives some characteristic Migration when DNA is shuffled about randomly to make offspring Drift an accident in DNA ____________________________________________________________________________________ Which of the following is NOT part of the Hardy-Weinberg Law? a) Population must be large b) Mutations must occur c) Reproduction must be random d) DNA must change quickly _____________________________________________________________________________________ The viceroy looks like the Monarch, which is protected by poison. This is…. a) warning coloration b) camoflage c) mimicry __________________________________________________________________________________ Sometimes a big mutation proves to be very valuable, and the population starts to show this trait. a) directional selection b) stabilizing selection c) disruptive selection _____________________________________________________________________________________ This type of selection would lead a population to break into two or more groups. a) directional selection b) stabilizing selection d) disruptive selection ______________________________________________________________________________________ When a species has members that come to develop traits that fill a new niche, it's called… a) geographic isolation b) reproductive isolation c) adaptive radiation d)polyploidy _________________________________________________________________________________ A type of salamander loses its skin coloring and eyesight over time. This is an example of… a) geographic isolation b) reproductive isolation c) adaptive radiation d)polyploidy _________________________________________________________________________________ Which of these is an example of convergent evolution? a)bug eyes and moth antenna b)human arms and chimp arms c)bird wings and bug wings d)none of these _________________________________________________________________________________ The acacia tree gives food to ants and has places for them to live inside. The ants protect the acacia. This is an example of… a) convergent evolution b) coevolution c) natural evolution d) beneficial evolution ____________________________________________________________________________________ One creature that we have observed evolution taking place is the… a)pine tree b)moth c)human d)elephant ______________________________________________________________________________________ Some bacteria types have become resistant to antibiotics. This is because of… a) Mutations b) Recombination c) Migration d) Drift _____________________________________________________________________________________
