A tick population in a rural, wooded area uses deer as its primary host species. Eventually, humans begin to move into the area, bringing their pets along with them. Certain individuals within the tick population start to use dogs as their primary hosts, and eventually start to prefer dogs over deer. Other individuals continue to use deer for their primary host. Could this difference in host preference lead to speciation? Why or why not? Select all correct answers.
_____ Yes, because temporal isolation could occur due to differences in host quality.
_____ No, because the ticks inhabit the same region and therefore experience the same mechanisms of evolution.
_____ Yes, because the ticks' host preference may be inherited, leading to an accumulation of genetic differences between ticks that use deer and ticks that use dogs.
_____ No, because one of the hosts will lead to higher fitness and the ticks that prefer the other host will be eradicated.
__X__ Yes, because temporal isolation could occur due to differences in host quality.
_____ No, because the ticks inhabit the same region and therefore experience the same mechanisms of evolution.
__X__ Yes, because the ticks' host preference may be inherited, leading to an accumulation of genetic differences between ticks that use deer and ticks that use dogs.
_____ No, because one of the hosts will lead to higher fitness and the ticks that prefer the other host will be eradicated.
