Textbook Question
Chapter 17, Problem 16BS
The size of the human brain has not changed in the last 100,000 years, but human culture has changed a great deal. As a result of our culture, we change the environment at a rate far greater than the rate at which many species, including our own, can evolve. What evidence of rapid environmental change do you see around you? What aspects of human culture are responsible for these changes? Do you see any evidence of a decrease in the rate of human-caused environmental changes?

As you can see, there is a big difference between the biological and social cultural features between that Iceman and you. Why do you think changes happened in all aspects of your life from time to time?
Some scientists say that modern medicine and better sanitation are slowing down or altering the course of human evolution in highly developed countries today. As a result, evolution in humans today has gone from survival of the fittest to survival of almost everyone. Do you think that this idea is valid? Why or why not?
Modern humans over-eat sugar because we love it so much. One might ask, “why are we designed by evolution to love sugar when sugar is so bad for us?” How does the concept of the “environment of evolutionary adaptation” (EEA) help us explain this and some otherwise puzzling behaviors of modern humans? Please explain EEA first.

- Bergman's and Allen's rules apply to many animals, not just humans. Look at the following images of two different hare species. Based on what you can see in the images and using only Bergmann's Rule and Allen's Rule, which of these hares is adapted for a cold climate and which is adapted for a hot climate? What adaptations do they have to suit their environments? Do humans living in similar environments share the same adaptations? Remember, you must use Bergman's and Allen's rules in your analysis, so be sure you know these rules and refer to them.arrow_forwardWhich of the following is correct concerning adaptations? (Choose one.) Group of answer choices a)They always increase an organism's ability to survive better than other individuals in the population. b)They can increase an organism's ability to survive better or reproduce better than other individuals, but not both at the same time. c)They increase an organism's ability to reproduce better than other individuals in the population, in a given environment. d)They result from any mechanism of evolution.arrow_forwardWhich type of environment would tend to reduce genetic variation in a population because of evolution by natural selection? an old growth forest with trees that are over 1,500 years old a tropical rainforest that is being deforested for farmland an ocean ecosystem that is becoming more acidic grasslands that are undergoing severe droughtarrow_forward
- Out of the three, what would be an example of evolution? A population of green beetles changes over many generations to a population of brown beetles. Individual green beetles in a population become brown because of what they are eating. The environment where a population of green beetles is living changes, becoming much more cold over time.arrow_forwardWhat is one way you can use the theory of evolution to understand things in everyday life ? This can be anything from a better understanding of a disease to a deeper appreciation for art or philosophy.arrow_forwardIn the biological sense of the term (and not psychological!), why can't we say that individuals evolve? (In other words, why do we say that only populations evolve?)arrow_forward
- In many ways, modern human lifestyles are at odds with our bipedal locomotion. At no point in history have humans been as inactive as today (especially in developing nations), which has led to a number of physical ailments, such as obesity, loss of mobility, and low back pain. What are some other impacts of evolution on our species? What are some ways we can alleviate these problems? You should include any recommended study tips, review videos, or other materials.arrow_forwardPesticides can be used to control a variety of pests, such as insects, weeds, rodents, bacteria, fungi, etc. Over time many pesticides have gradually lost their effectiveness because pests have developed resistance – a significant decrease in sensitivity to a pesticide, which reduces the field performance of these pesticides. 1. Why do pesticides lose their effectiveness over time? Use the theory of natural selection and evolution to explain.arrow_forwardYour friend remarks, "The giraffe stretched its neck while reaching for higher leaves; as a result, its offspring inherited longer necks” Which statement is the best response to correct your friend’s misconception? Group of answer choices Overproduction of offspring leads to a struggle for survival. Disuse of an organ may lead to its eventual disappearance. Characteristics acquired during an organism's life are generally not passed on through genes to its offspring. Only favorable adaptations have survival value.arrow_forward
- The start of the sociocultural evolution of humans can be traced to the Stone Age, particularly during the Paleolithic era (Old Stone Age). The primary means that drive the sociocultural aspect of human life during this time actually were the means of the earliest humans to survive, which was FORAGING OR HUNTING-GATHERING. Describe how foraging or hunter-gathering contributed to the evolution of the sociocultural dimension of human life.arrow_forwardAll land vertebrates, including humans and dinosaurs are descended from early tetrapods like Tiktaalik. Since the Devonian, land vertebrates have adapted to a wide variety of environments. What environmental changes might cause certain mutations to propagate through a population? A cooling period which favors insulating characteristics like feathers A mass die-off of plants which favors smaller forms with more efficient metabolism A warming period which favors efficient cooling strategies All of these are correctarrow_forwardIs evolution important to all living things, and why do we need to adapt to the ever-changing conditions in which we find ourselves?arrow_forward
