5. Bergmann's and Allen's rules apply to many animals, not just humans. Use material in your classroom, on- line, or in books to locate images of a black-tailed jackrabbit (Lepus colifornicus) and a snowshoe hare (Lepus americanus). Based on what you can see in the images, which of these hares is adapted for a cold climate? Which is adapted for a hot climate? What adaptations do they have to suit their respective environments? Do humans living in similar climates share the same adaptations? 6. This question may be completed independently or as a group discussion. Humans are unusual because our cul- tural practices can actually change our environmental circumstances. We can impact the environment in which natural selection acts on our traits. Describe how this process has played out in the evolution of adult lactose tolerance. Describe how this process has played out in the maintenance of the sickle-cell trait. Can you hypothe- size any similar situations where our future evolution may be impacted by cultural practices we have today? 7. So far, we have primarily discussed human adaptations independently of one another. In real life, of course, each person has numerous coexisting ancestral adaptations. Ignore what you know of your family history and consider only your physical traits for the following adaptations: skin color, lactose tolerance, and body shape. Based on these three traits, in what part of the world might your ancestors have originated? Do all three of your traits Suggest similar ancestry? Be sure to explain your hypothesized determination using evidence related to all three traits and be sure to think about all the forces of evolution that might impact your unique history (such as gene flow and the founder effect). maladaptive) in today's world. For example, h helpful during times when food is limited su we considered various human adaptations. It is important to remember that many of these ons evolved to suit environmental circumstances of the past, and they may be less helpful for even today's world. For example, humans are adapted to store fat in the body for later use. This is very e times when food is limited (such as during extended droughts) because it allows us to live on the dy. However, in much of the world today, there is food abundance rather than food scarcity.Explanation / Answer
5. Snowshoe hares are mostly found in north america where it under go changes during change in environmental or climatic conditions. The snowshoe forms fur on their foot during winter which helps from by preventing sinking into snow and protect from from freezing temperatures. During summer the feet turns into rusty brown in colour.
The black tailed rabbit mostly found in aouth part of america. These hares does not undergo changes in physical appearance due to change in environment or climate conditions. The would not change their habbit or habitat throughout the year.
No, humans cannot live in this type of climate conditions.
6. Generally the environmental conditions show effect on health of the human. Due to increase in pollution there will be a effect on environment. The environment condictions ahow efect on sickle cell disease and lactose tolorence. Generally people who lives in cold enironments are more born to SCD. It can be redused by living in warm temaratures. Due to damage of ozone layer their will be effect on human health. The people who show deficiency in vitamin D are used to take milk for lactose. Sun light plays important role in production of vitamin D. So if damage occurs on environment there will be occurance of fall of lower wave length rays which show effect on health.
