QUESTION 3 Darwin's theory of natural selection explains: O The way life began. O The way evolution works at the genetic level. The way dinosaurs became extinct. O That traits within a breeding population that are adaptive to specific environmental circumstances become more numerous in that population over time.

Question:- Of the three examples in which humans have influenced the evolutions of urban populations of animals (i.e. house finch, white footed mouse, and mosquitoes), which do you think is most likely to result in speciation and why?
17 The graph below represents the number of brown and green beetles collected in a particular ecosystem. Change in Coloration of Beetle Population Green beetles Brown beetles Time (years) The change observed in the number of green and brown beetles in the population is most likely due to (1) natural selection (2) selective breeding (3) gene manipulation (4) a common ancestor [4] Number of Individuals
Which components of speciation would be least likely to be a part of punctuated equilibrium? a division of populations a change in environmental conditions ongoing gene flow among all individuals a large number of mutations taking place at once
Question: Human hunting of bighorn sheep has focused on ‘trophy’ sheep which are the largest male sheep with the longest horns. Consequently, over the last 30 years of hunting pressure, average weight of male sheep has declined by ~20 kilograms and average horn length has declined by ~25 centimeters. These changes are evidence of _________ selection. A- Stabilizing B- Diversifying/Disruptive C- Directional D- There is no evidence of selection in this system
Exercise 4: Population Genetics 1. How do the genotype frequencies (or number of kittens) among the parents compare to with those of their kittens (2nd generation)? 2. Compare your results to those of another lab group and explain what you see here. Why do you think this is the case? Exer How the l pres A re ac N th 20 3. Is this population in Hardy-Weinberg Equilibrium? What does that tell you about this population in relation to the 4 conditions needed for equilibrium? Exercise 4.2 Evolving Populations In this part of the exercise, we will use the toothpicks to illustrate the effects of natural selection in our population of cats. In our small town, people don't usually set out food for the cats who live there, because they are fairly unobservant and didn't notice all those solid black cats hiding in the shadows. But now, with the mutation creating white spots on some of the cats, people are noticing these cats and leaving food out. Let's assume that only the cat who's seen actually…
