Question

1. What are the main differences between the subject areas in human biology, human evolution, and human ecology? What are the Key similarities?

2. From studying nonindustrial societies, what can we learn about enviormental problems like pollution and global warming?

3. What are the main features of a hunter-gatherer lifestyle? What insight does the study of ! Kung hunter-gatherers offer for understanding human biology?

Answer 1

1.Human biology	human evolution	human ecology
The study on this topic,mainly focus on the basic structure and function of the human body. We can also learn about the anatomy and physiology of human cells. are tissues. We learn about the human organ systems and biochemical pathways.	The study of paleoanthropology is the basic platform to know about the human evolution. By study of this topic we know about the primitive ancestor of human and how humans are originated and about all the stages of development of mordern humans. Also the development of human brain and their characteristic changes or their behavior changes are also learn from this topic.	Human ecology is mainly focus the interdisciplinary and transdisciplinary study of the relationship between humans . From study of this topic we learn about the interaction of humans with natural, social, and environments or with other species.

From this three subject, the main similarity is we can learn a detailed account about the human nature and their impact on nature.

2. From studying nonindustrial society , it is clear that this society driven by the use of technology to enable mass production, supporting a large population. But various demerits are also occured like enviormental problems like pollution and global warming.

The poor indoor air quality in the home and workplace influenced by nonindustrial activities. It also causes greater risk of adverse health effects due to more air pollution. Along with particulate matter, gases such as ozone, nitrogen dioxide, carbon monoxide, and sulfur dioxide; microbial and chemical volatile organic compounds; passive smoke; and outdoor ambient air are the most common types of air pollutants.

Global warming is the continuous increase of  temperature of the Earth's climate . This occupies due to the high concentration of those gases.

3.main features of a hunter-gatherer lifestyle givrn below:-

They tend to be small, with fewer than fifty members.

the hunter-gatherers actively killed animals for food

all food is obtained by foraging.

hunting wild animals, fishing, and gathering wild fruits, berries, nuts, and vegetables to support their diet.

Kung hunter-gatherers peoples who live mostly on the western edge of the Kalahari desert. They offer for understanding human biology, - Kung society men and women live together in a non-exploitative manner, displaying a striking degree of equality between the sexes.from this information we know that they maintained the numbet of male and females within their society which is very important for modern community also.

I hope this answer will definitely help you. Please give me likes. All the best. THANK YOU STAY SAFE.
