Document Summary

Evolutionary developmental science: breadth and scope of theory- nothing in biology makes sense except in the light of evolution - theodosius. Dobzhansky: evolution is the only unifying scientific theory in the study of life, observational methodology gives very contextual, and highly valid, data, evolutionary perspectives. What is evolution: evolution is a theory that explains the diversity and function of all living things, evolution is a theory, but so is electricity or gravity, evolution is the most powerful, and widely accepted, theory in biology. Five components of darwin"s evolution by natural selection. The meaning of life: we know the biological meaning of life! It is simply to pass on one"s genes to future generations. Individual: old zebra are 4-5 years old, 5 year olds are weaker, and make the herd weaker on average, dies for the good of the species at 4, produces 1 child/yr.

Natural selection and evolution

Correctly complete the following paragraph to explain the relationship between natural selection and evolution.

Terms may be used more than once.

Within a population of fish, ____________ exists in the form of body color. Some fish are orange and some fish are red.

The fish population lives on an orange reef bed. Because of this, fish that are ____________ are able to blend in and resist predation.

Because fish that are ____________ are more likely to blend in and resist predation, they are more likely to survive to reproduce.

Fish produce ____________ offspring which ____________ the genes for body color.

After several generations, one can expect the fish population to have a ____________ portion of orange individuals compared to red individuals.

In this manner, ____________ is driving ____________ .

Choice of words:

natural selection

genetic variation

red

evolution

smaller

many

inherit

larger

orange

few

Describe the theory of natural selection Which of thefollowing BEST describes the theory of natural selection? CHOOSEONE

	1 The genetic make-up of apopulation gradually changes from one generation to the next.
	2 Living organisms change overtime.
	3 Each species produces many moreoffspring than can survive long enough to reproduce. The offspringthat do survive contain genes that are inherited from theparents.
	4 There is variation among themembers of a species. Some of this variation is geneticallydetermined and so can be passed on to future generations.
	5 Some individuals have genes thatincrease their chances for survival and reproduction. Theseindividuals are more likely to reproduce and pass on their genes,causing their genes to become more common in the nextgeneration.
	6 There is a struggle for existenceamong the members of a population.

Which statement about evolution by natural selection isfalse?

Natural selection allows organisms with higher fitness toreproduce more successfully.

Natural selection favors those traits that confer higherfitness in the environment.

Natural selection is a random change in characteristics of apopulation over generations.

Evolution by natural selection affects populations oforganisms, not individual organisms.

An organism's fitness depends on its _____.

ability to survive and reproduce

ability to swap genetic material with other organisms

physical size

ability to mutate

population

Consider the heavily armored stickleback fish population thatcolonized the lake. If all the individuals in that population weregenetically identical, what do you predict would happen when theycolonized the freshwater lake?

The population would increase, as it has increased foodresources.

The population would evolve through natural selection to bebetter adapted to its environment.

The population would decrease due to more juvenile fish beingeaten.

No answer text provided.

Which of the following are adaptations?

Thicker beaks on finches that allows them to eat large seeds,when large seeds are the most abundant.

Less armor on stickleback fish in freshwater that allows themto grow faster to avoid predation.

More armor on stickleback fish in the ocean that prevents themfrom being eaten by larger predators.

None of the above.

All of the above.
