Answer :
Answer:
- Natural selection and adaptation:
Living organisms are always in the process of adaptation to the surroundings or the environment in which it lives from one generation to another. As, over centuries men are also subjected to evolution.
- Men living in the high grounds and those living in the lower altitudes:We can analyze the case of people living in the different regions across the globe. As there are difference among the skin tone, there heart rate and the instinct to survive in harsh conditions. Because, if a generation of people migrates from a lower altitude region into a area of higher altitude then there will be an evolution or set of changes inside the living being body mechanism or more over cellular activities. And thus there kids will have a more capacity in terms of enduring the low rate or level of oxygen in the higher altitudes regions.So, it can be analyzed over the period of one and half decade of time duration, to see how the different individuals evolve through time as per the conditions provided to it.
- While there can be also the changes seen in the skin tone of the people who's ancestors have migrated long before they were born in the high altitude areas.
Adaptation is the process of change in which organisms adjust to the environment. Natural selection is the process in which organisms better adapted to the surrounding will tend to survive. The heart rate, skin tone, development of organs, are some of the examples of adaptation and natural selection.
Men living in the higher altitudes and those living in lower grounds:
- People live in different regions, weather, and height across the globe. The difference in skin tone, heartrate, oxygen in the atmosphere, and the instinct to survive in extreme conditions is observed. The people migrating from lower ground to higher ground will experience evolutionary change for several years. The cellular activities and heart rate will be evolved. The next generation of migrated people will have more tendency to survive in low oxygen at high altitudes. Thus, evolution is a continuous process whose changes will be seen after several years.
- The skin tone of the person can also evolve as the people whose ancestors have migrated long before will carry the changes acquired by them.
Therefore, oxygen level, and skin tone of people can be evolved.
