Misconceptions in Evolution
Write a misconception and the correct evolutionaryinterpretation for the following statements:
    Example:
Statement: Over time, the average length of giraffe necks hasincreased.
Misconception: Short-necked giraffes stretched their necks byreaching for food that was high in trees. They passed this newacquired trait on to their offspring, which were born with longnecks.
Correct interpretation: The ancestral giraffe population happenedto have some short-necked giraffes and some slightly longer-neckedgiraffes. The giraffes with slightly longer necks could reach morefood (or could win more fights, etc.) and had superior survival andreproduction. Over time, the long-necked giraffes became morecommon in the population. Repeated over many generations, thisresulted in evolution of longer and longer necks.
A) After the Industrial Revolution, moths changed from beingmostly light to being mostly dark.
B) The incidence of antibiotic-resistant bacteria is on therise, many bacteria have resistance mutations.
C) Heterozygotes which carry the gene for sickle-cell anemia(but aren't greatly affected by the disease) are resistant tomalaria.
