Question

Quizplus · Accepted Answer

The number of different types of organisms found on Earth is primarily a result of natural selection and speciation. Over time, small differences between individuals of the same species can accumulate and eventually lead to the formation of new species. This process is driven by natural selection, where organisms with certain traits are better able to survive and reproduce than others. As these traits become more common in a population, they can eventually lead to the formation of new species with unique characteristics. This process has led to the incredible diversity of life on Earth. Continental drift and Darwin's theories may have influenced how we understand and approach the study of biodiversity, but they are not the primary drivers of the number of different types of organisms found on Earth. Common descent also plays a role in explaining the relationships between different species, but it is not the primary factor driving the evolution of new species.
