Explanation:
Communities in a primary succession include
-barren rock
-bacteria and fungi
-mosses and lichen
Further Explanation:
Ecological communities are highly dynamic- they gradually evolve. Typically their progression involves:
- colonizing species exploiting uninhabited areas (Primary succession)
- becoming a habitable and increasingly complex community
- there is increased diversity of organisms (Secondary)
The makeup of biological communities is crucial to defining Primary and Secondary succession; eventually, through changes in this makeup, a steady-state or equilibrium is reached called a climax community. While Primary succession starts off with the modification of a previously unoccupied area along with increasing variation; secondary succession begins after major disruption in the community such as fires, storms and flooding.
However, the process of becoming a climax community can be pretty complicated- it is very dependent on other factors like temperature and rainfall. Communities that experience rapid change, frequent major disruptions and even human intervention, are less likely to attain a stable equilibrium and may never become climax communities.

The correct answer is plants
Variation becomes an advantage if neither of the individuals
is having detrimental traits. If neither of the individuals is having the
detrimental trait then that means that a bad gene is being introduced in the
population. Other times, variation is an advantage since it provides the population
with better traits and devices to use on their environment. This is crucial
since the environment changes over time.
Answer:

I believe the answer is A. A single origin of modern people and eventual replacement of archaic homo sapiens throughout Africa, Asia and Europe. Out of Africa model; asserts that modern humans evolved relatively recently in Africa, migrated into Eurasia and replaced all populations which had descended from Homo erectus. After Homo erectus migrated out of Africa the different populations became reproductively isolated, evolving independently, and in some cases like the Neanderthals, into separate species. Homo sapiens arose in one place, probably Africa. Homo sapiens ultimately migrated out of Africa and replaced all other human populations, without interbreeding modern human variation is a relatively recent phenomenon.
