After which event could it be said that evolution has occurred?
An individual is born with six fingers on one hand instead of five.
An animal’s white winter coat is replaced by a darker coat in the spring.
A new predator comes into an environment.
An allele frequency in a population changes over time.
The event could be said that evolution has occurred Option D. An allele frequency in a population changes over time.
Evolution can be defined as the process through which different species are believed to have evolved from earlier forms over time. This process involves genetic variation within a population, natural selection, and reproductive isolation. Evolution takes place when allele frequency changes over time within a population.
The allele frequency is the frequency of occurrence of an allele (version of a gene) in a population. Allele frequency changes can take place through genetic drift, gene flow, and natural selection. When these changes occur over time, evolution can be said to have occurred. The correct option from the given alternatives is option D.
The other options given are not indicative of evolution:
A. An individual being born with six fingers on one hand instead of five is a mutation, which can cause variation but may not lead to evolution. This is because it is not a change that can be inherited by future generations.
B. An animal’s white winter coat is replaced by a darker coat in the spring as an adaptation to changing seasons. This is also not indicative of evolution as it does not involve genetic variation in a population.
C. A new predator coming into an environment is a change in the ecosystem, which can affect the population size and dynamics of the existing species, but it does not necessarily lead to evolution. Therefore, the only option that describes a genetic change in a population is option D, where an allele frequency in a population changes over time. This change is an important aspect of evolution. Therefore, the correct option is D.

reasons why Europeans came to East Africa
These are some of the reasons why Europeans came to East Africa.
1. As a part of Industrialization: For spreading their market and exploring resources.
2. To protect trade routes: They need raw materials for civilization and to set up their business colonies.
3. In search of Manpower and labor: As industrialization begins there comes a tremendous need for labor soon after the plague spread.
4. For diamond extraction: Discoveries of diamonds is another reason that attracted Europe to Africa.
5. To establish political power and supremacy: By establishing colonies they could exploit Africa by exploiting and exporting the resources and manpower, thereby enhancing Europe's wealth.
