How would you explain the theory of natural selection?
Natural selection is the process through which populations of living organisms adapt and change. Over time, these advantageous traits become more common in the population. Through this process of natural selection, favorable traits are transmitted through generations.
What is the summary of Darwin’s theory of evolution?
| — | More organisms are produced than can survive because of limited resources. |
|---|---|
| — | Organisms struggle for the necessities of life; there is competition for resources. |
| — | Individuals within a population vary in their traits; some of these traits are heritable — passed on to offspring. |
What is Darwin’s summary and conclusion of his theory of natural selection?
The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
How would the theory of evolution by natural selection explain the well developed ability of human beings to be social?
How would the theory of evolution by natural selection explain the well-developed ability of human beings to seek socialization and to socialize effectively? It is an ability that has developed over time because it promotes survival. Conjoined twins are also which type of twin?
How do you summarize evolution?
In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species? are related and gradually change over time.
What did Darwin propose as the mechanism of evolution summarize this mechanism?
The mechanism for evolutionary change proposed by Charles Darwin was “descent with modification.” Darwin perceived unity in life, with all organisms related through descent from some unknown ancestor. Over time they accumulated diverse modifications, or adaptations, that fit them to specific ways of life.
Can natural selection occur without evolution?
Natural selection can occur without leading to evolution if differences among individuals are not genetically based. Nonetheless, much of the phenotypic variation within a population is, in fact, genetically based; consequently, natural selection often does lead to evolutionary change.
Can you evolve without natural selection?
According to the neo-Darwinian theory of evolution, such a mode is possible only as neutral evolution. However, it can be demonstrated that such an adaptive mechanism of evolution without natural selection is theoretically possible, and may play a significant role in evolution.
