Week 14 Quiz

Question 1 

A donkey and a horse can mate and produce a mule. Why are they not considered to be the same species? 

  A. the mule can only mate with donkeys

  B. the mule will only mate with other mules

  C. the mule will only mate with horses

  D. the mule is sterile

  E. the mule is bigger than both the donkey and the horse

 

Question 2 

At a family get-together, your uncle says “I don’t believe in that evolution stuff. Scientists are always saying that something evolved because of ‘a gene for eyes’ or ‘a gene for wings’. Well, that’s crazy – how can one single gene build an eye or a wing?”

How do you reply? 

  A. Yes, lots of genes are necessary to make an eye or a wing – but a mutation in just one gene might change development, to make a change in how the eye or the wing works.

  B. You’re right – for evolution to work, hundreds or thousands of genes would have to mutate all at once, just the right way. It’s not possible.

  C. You’re right – for evolution to work, hundreds or thousands of genes have to mutate all at once, just the right way. It doesn’t happen very often, but evolution takes place over millions of years.

  D. There are thousands of regular genes that build parts like an eye or a wing. But then there are special “evolving” genes that can change how parts work. Only the second set of genes matters for evolution.

 

Question 3 

The difference between dispersal and vicariance when considering allopatric speciation is that dispersal has organisms leaving the homeland for a different one while vicariance 

  A. is when a natural occurrence physically separates the population

  B. only happens to the offspring of the original species

  C. is when members are forcibly moved to another location

  D. windstorms carry members of the population far away

  E. members of the population leave due to depleted resources

 

Question 4 

Two species of birds have different mating songs and so do not interbreed. This is an example of ________

  A. habitat preference

  B. allopolyploidy

  C. temporal isolation

  D. behavioral isolation

 

Question 5  

Evolution is 

  A. a strong hypothesis

  B. not seen in the fossil record

  C. supported by all scientific evidence examined so far

  D. very difficult to study since it takes so long

 

Question 6 

Reproductive barriers increasing over time would lead to ________.

 

  A. stability

  B. reinforcement

  C. fusion

  D. stable hybrids

 

Question 7 

 

A superhighway is put down in a field separating a population of snails. Over time, they acquire mutations and become two different species. This is an example of ________ speciation.

  A. behavioral

  B. islolating

  C. sympatric

  D. allopatric

 

Question 8

In the process of adaptive radiation, there is usually one species from which others will quickly diverge. This original species is known as the

  A. founder species

  B. original isolate

  C. primary progenitor

  D. radiating organism

 

Question 9

 

The first bird that evolved the ability to fly now had habitats never before available and soon branched out into many different species utilizing different resources, which is an example of ________.

  A. mutational isolation

  B. hybrid viability

  C. ecological barriers

  D. adaptive radiation

 

 

Question 10  

The place where Darwin noticed finch and tortoise differences that helped him develop his theory of evolution was ________? 

  A. the Malay Archipelago

  B. the Galapagos Islands

  C. Australia

  D. Africa

  E. Brazil
