The three pillars of Darwin's theory of evolution are genetic variety, fitness, and adaptation. Overproduction and competition are other crucial components of this process.
What Darwin's theory of evolution by natural selection?Charles Darwin's theory of evolution is known as natural selection. Due to the limited supply of resources in nature, animals have inherited traits that aid in both survival and reproduction.
Typically, produce more offspring than their contemporaries, leading to an increase in the frequency of such traits across successive generations.
Natural populations exhibit variation, and every population has more offspring than the environment can support. The result of this Overproduction is that those people who have the highest level of environmental genetic fitness will have offspring who are better able to compete in that environment.
Therefore, Genetic variation, fitness, and adaption are all factors in Darwin's theory of evolution.Overproduction and competition are other crucial components of this process.

Gravity
Explanation:
Gravity keeps the planets, comets and meteors in orbit around the sun. The sun is bigger and heavier than other planets etc, this causes the planets to be pulled and kept in orbit around the sun.

3. Darwin surmised that all life on Earth was connected, like branches on a tree of life. What would the trunk of this tree represent?
Answer:
El árbol de la vida o árbol universal de la vida es una metáfora, modelo y herramienta de investigación que se utiliza para explorar la evolución de la vida y describir las relaciones entre organismos, tanto vivos como extintos, como se describe en un famoso pasaje de El origen de las especies (1859) de Charles Darwin.2
Explanation:
characteristics that scientists study to determine if a new species has been
discovered
Answer:
When ecologists travel to regions where they are not familiar with the plants and animals, they read field guides about the flora and fauna. Many of these guides have photographs, keys to species recognition, and descriptions of size, color, and general appearance.
