What were the three key observations made by Charles Darwin that allowed him to deduce that natural selection is the primary driver of evolution?

What were the three key observations made by Darwin that allowed him to deduce that natural selection is a primary driver of evolution? Organisms produce more offspring than survive, variation exists among members of populations, and advantageous variations increase in relative frequency over time.

Who was the scientist whose work provided the foundation for later understandings of genetics group of answer choices?

Gregor Mendel was an Austrian monk who discovered the basic principles of heredity through experiments in his garden. Mendel’s observations became the foundation of modern genetics and the study of heredity, and he is widely considered a pioneer in the field of genetics.

What is the primary driver of evolution?

Genetic variation is the presence of differences in sequences of genes between individual organisms of a species. It enables natural selection, one of the primary forces driving the evolution of life.

What Did Mendel’s pea plant experiments demonstrate quizlet?

Mendel’s plant experiments demonstrated that: traits inherited from each parent blended together in the offspring. traits are passed on from parent to offspring as discrete units. traits are passed on from parent to offspring as discrete units.

What are the three key things that contribute to the process of evolution?

Evolution is a consequence of the interaction of four factors: (1) the potential for a species to increase in number, (2) the genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for an environment’s limited supply of the resources that individuals need in order to …

What trait did Mendel study in the pods of pea plants?

He self-pollinated plants until they bred true – giving rise to similar characteristics generation after generation. He studied easily distinguishable characteristics like the color and texture of the peas, the color of the pea pods and flowers, and the height of the plants.

Why are Darwin’s finches good examples of natural selection?

Darwin’s finches are an excellent example of the way in which species’ gene pools have adapted in order for long term survival via their offspring.
