What is the statement for the Theory of Evolution, and does this statement include a description of the evolution of humans or other organisms? If you answer is no, then explain 1) how the Theory of Evolution is related to evolutionary lineages of humans and other organisms and 2) why it is appropriate to teach the Theory of Evolution. If your answer is yes, then 1) provide the definition of a Scientific Theory (as provided in lecture) versus hypothesis and 2) analyze the evidence supporting or refuting both the Theory of Evolution and the evolution of humans or other organisms.

http://www.nature.com/scitable/knowledge/library/overview-of-hominin-evolution-89010983 ... In 1871, Charles Darwin made one of the boldest scientific predictions ever: that Africa was the likely location where the human lineage diverged from all other animal species. The validity of his prediction is supported by both fossil and DNA evidence. The accompanying article Overview of Hominin Evolution by Herman Pontzer explores the evolution of our own species beginning just prior to the divergence of our lineage from that of chimpanzees and bonobos. Read through the article and answer the following questions:

1. Was the last common ancestor of humans and chimpanzees (HC-LCA) more similar to living apes or humans? Explain.

2. Why is the comparison of human evolution to a life boat rather than to a powerful ship more appropriate?

Select the statements that correctly represent the theory ofevolution. Select all that apply.

Evolution is partly about inheritance. Evidence of evolution isseen in structures such as wisdom teeth and the tail bone inhumans. These structures are thought to be “left over” from ourancestors and no longer appear to have any essential function inmodern humans.

Natural selection means that today’s organisms are perfectlyadapted after millions of years of fine-tuning. No further changesare necessary because of all the progress that has been made bynatural selection.

We can see evidence of past natural selection in adaptationssuch as the camouflage of moths perched on the bark of their hosttree. We can also see natural selection at work today if we trackhow populations change in rapidly changing environments.

The theory of evolution does not apply to life today. It isstrictly about the history of life: what happened in the past asseen in fossils.

Scientists disagree about the main ideas of evolutionary theorybecause of incomplete or conflicting evidence.

Question 2

Select one answer.

10 points

The ability or tendency of organisms and cells to maintainstable internal conditions is called

metabolism

homeostasis

emergent property

evolution

Question 3

Select one answer.

10 points

Why do organisms maintain fairly steady conditions within theircells and bodies?

They need to keep conditions stable so that they can obtainfood.

Organisms just change along with whatever is happening in theoutside world, which is usually quite steady.

They must maintain stable conditions to keep their enzymesworking and generally to enable the chemical reactions of life.

Unstable conditions will destroy the DNA in cells; this is themost important risk for a cell facing physical or chemicalstress.

Question 4

An organism or cell exhibits ____________ when it maintainssteady internal conditions despite changes in the outerenvironment.

homeostasis

evolution

balance

natural selection

Which type of molecule best illustrates the very strongrelationship between structure and function in biology?

enzymes

oxygen gas

all kinds of organic matter

water

Question 6

Select one answer.

10 points

Which best expresses how nutrients and energy move throughlife?

Nutrients flow from sunlight to organic matter to heat. Energycycles among all life forms.

Nutrients cycle among all life forms. Energy flows from sunlightto chemical energy to heat.

Nutrients and energy both are continually recycled in a greatcircle of life.

Question 7

Select one answer.

10 points

Which of the following is not a recurring theme in biology?

Living organisms maintain homeostasis.

Energy flows through living systems while matter isrecycled.

Evolutionary processes explain both the unity and adaptivediversity of life.

All of these are recurring themes.

Question 8

Select one answer.

10 points

Which statement about evolution is FALSE?

According to evolutionary theory, you are related to abacterium, to a yeast cell, to a snake, and to a whale. In fact,you are related to every species now alive on Earth, and to fossilspecies like dinosaurs as well.

Evolution occurs constantly, without end; there is no endpointin evolution.

Natural selection acts on genetic differences within apopulation to cause evolution. Individuals do not evolve.

Natural selection is about slow but steady progress. Through it,populations constantly get better-adapted. When this process iscompleted for all populations, evolution will come to a stop.
