According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

What is Darwin's theory of natural selection?
More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.
What animal did Darwin suggest to natural selection?
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.
What did Darwin call the process by which better adapted organisms are more likely to survive?
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success.
What are adaptations according to Darwin?
A Darwinian adaptation is an organism's feature that was functionally designed by the process of evolution by selection acting in nature in the past.
What is the role of Charles Darwin in relation to concept of species?
Charles Darwin is credited with suggesting that species evolve over time and that the mechanism by which they evolve is natural selection. Charles Darwin wrote a book called, "On the Origin of Species by Means of Natural Selection".
What is Darwin's theory of origin of species?
Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
What animals did Charles Darwin discover?
His discoveries included four different species of giant ground sloth (some of the largest land mammals ever to have lived), a gomphothere and the remains of an extinct horse. Many of Darwin's fossils survive, at the Museum and elsewhere.
What animals did Charles Darwin study?
The mystery of evolution became clear to Charles Darwin after his observation and study of birds rather than from the reptiles. Such birds, now better known as Darwin's Finches, would help him crack the case more than anything else. Charles Darwin collected finches from the different islands.
What did Darwin notice about the animals on these islands?
In this island Darwin noticed that most species were similar but different from other in the other islands, giving enough evidence to theorize that species change and this is related to their feeding and surroundings. He collected finches that helped him to understand this resolution.
What did Darwin think would happen to the animals in a species that were best adapted to their habitat?
Individuals with characteristics most suited to their environment are more likely to survive and reproduce - commonly known as 'survival of the fittest'. The alleles that code for a phenotype that allows these individuals to be successful within their environment are passed on to their offspring.
Does natural selection lead to adaptation?
Natural selection leads to adaptation, that is, to a population dominated by organisms that are anatomically, behaviorally, and physiologically well suited to survive and reproduce in a specific environment. ... Adaptation also means that the distribution of traits in a population can change when conditions change.
Why is Darwin's theory of natural selection sometimes described as survival of the fittest?
Charles Darwin popularized the concept of survival of the fittest as a mechanism underlying the natural selection that drives the evolution of life. Organisms with genes better suited to the environment are selected for survival and pass them to the next generation.
How do animals adapt to their environment?
Animals depend on their physical features to help them obtain food, keep safe, build homes, withstand weather, and attract mates. These physical features are called called physical adaptations. They makes it possible for the animal to live in a particular place and in a particular way.
Did Darwin believe organisms adapt to their environment?
Darwin's theory of 'evolution by natural selection' relies on variation among individual animals or plants of the same species. ... Animals and plants poorly adapted to their environment may not survive and reproduce.
How do adaptations affect a species answer?
Adaptations affect a species because it affects where they live and how well they survive and reproduce in their habitats. Adaptations are responsible for making the species more genetically diverse. The evolution of organisms was connected with adaptation of organisms to changing environmental conditions.
