Answer:
However, the Galapagos finches helped Darwin solidify his idea of natural selection. The favorable adaptations of Darwin's Finches' beaks were selected for over generations until they all branched out to make new species. These birds, although nearly identical in all other ways to mainland finches, had different beaks.
Explanation:
Darwin's theory states that advantageous traits increase survival and reproduction. Galapagos tortoises and finches have adapted to their environments.
What is Darwin's theory of natural selection?Darwin's theory of natural selection is a fundamental principle in evolutionary biology. It states that the traits that provide an advantage to individuals within a population increase the likelihood of survival and reproduction. The process involves four key components: variation, heredity, selection, and time.
Within a population, there is genetic variation, meaning that individuals have different traits. Some traits may be advantageous, such as a thicker coat to survive colder temperatures or a longer beak to access food. Individuals with advantageous traits are more likely to survive and reproduce, passing their traits onto their offspring.
Over time, the frequency of advantageous traits increases within the population, leading to evolution. Natural selection is the mechanism that drives this process, allowing species to adapt and thrive in their environments.
