Can the environment and the heritage be used to describe evolution?

1 answer:

7 0

Evolution is caused by genetic mutations that become favorable for survival.

For example if a bird has a mutation that gives it a longer beak and it lives in an environment in which a longer beak lets the bird catch more food- the longer beak becomes a favorable trait.

Now the bird is able to survive “better” thus it lives longer(due to its ability to catch more food). Because of this it reproduces more and passes the trait on to its offspring.
Overtime this mutation takes over the population of birds in the area.

Based on the graph, it can be concluded that the population is increasing rapidly because of the youth of the population.

<h3>What is population?</h3>

The population of a species is the number of organisms of the same species found within a given habitat.

Population graphs are used to describe the trend in the population of a given species of organisms.

The factors that affects population growth of a country include:

fertility rates,
mortality rates or life expectancy,
the initial age profile of the population, and
migration

Given the population graph of the country, the conclusion can be drawn is that the population is increasing rapidly because of the youth of the population.

In conclusion, the higher the fertility rate the faster the population growth.
