Which of the following is not a part of darwin’s theory of evolution?
a. changes in organisms occur immediately.
b. organisms change over time.
c. species evolution occurs through natural selection.
d. organisms developed from common ancestors

Changes in organisms occur immediately are not part of Darwin’s theory of evolution.

Further Explanation:

“Darwin’s theory” of evolution states that the changes in the physical and behavioral traits of an organism overtime, allows it to better survive in a particular environment and leave more offspring.There are various loopholes in the evidence that support this theory, but the observation of the natural world has made scientists reject other theories, and regard this theory as the best explanation for the present-day functioning of the organisms and ecosystem. Darwin’s theory of evolution states that the organisms compete for the limited supply of resources and the ones, which are best outcompete others. Also, the ones which fit better in a particular environment are selected naturally and leave more offspring than others. This theory helps to know the ancestral lineage of a particular organism. For example, the functioning of homologous organs, such as phalanges in different organisms indicates their shared ancestry. Also, helps to understand the mechanism of adaptation and natural selection. For example, moths adapted for dark-colored wings instead of cream color, not to be easily visible by the predator.
