Natural selection works on mutations that are already in place. The environmental changes will select for certain mutations if the selective pressure is supplied long enough for several generations of offspring to carry a higher percentage of the mutation.
Natural selection can act relatively quickly, especially in response to sudden changes in the environment or when strong selection pressures are present. However, the speed of natural selection can vary depending on factors such as the generation time of the organisms involved and the strength of selection pressures. In general, natural selection is considered to be an ongoing and continuous process that can result in gradual changes over long periods of time.
Charles Darwin and Alfred Russel Wallace proposed natural selection as a mechanism of evolution independently in the 19th century. Their work laid the foundation for the theory of evolution by natural selection.
Evolution is enabled by natural selection: the ability of a species through its individuals to make long-term improved changes in its response to its environment through beneficial mutations, resulting in the species being able to reproduce itself more successfully than before.
No. Typically the symptoms of HD do not become apparent until long after a person would be of child bearing age.
The anteater has a long snout. Since the anteater is toothless, it has a long tongue that it uses to catch the ants. The anteater uses its snout and claws to reach into ant nests. The anteater has long hair as a protection against bites from the ants that they hunt and eat.
The insectivore that has a long tongue and eats ants is a aardvark. The aardvark also has a long nose.
One long argument with supporting evidence for the theory of evolution by natural selection. Starting with artificial selection, used as an analogue for natural selection, and ending with the distribution of animals, biogeography, Darwin showed the species arose through natural process over long lengths of time.
No. Not by a long shot.
The Holocaust has nothing to do with natural selection, or vice versa. The Holocaust was the result of atrocious crimes committed under the leadership of a few madmen, inspired by a long tradition of antisemitism. Natural selection is a model that describes differential reproductive success in natural populations, under natural circumstances.

The answer is a anteater. Let me know if there is any thing else.
The Giant Anteater is classed as 'Near Threatened' by the IUCN. As anteaters are placid creatures they are preyed upon by large cats such as Pumas and Jaguars. However, a cornered anteater will ride up on its hind legs, using its tail for support and use its long claws which are 4 inches long, to fight off the attacker. Anteaters are also hunted in South America for fur and food.
An anteater.
Natural selection is the type of selection that can result in a branching evolutionary tree if it goes on long enough. This is because organisms may eventually evolve into a distinct species.
The process of natural selection and evolution can vary in terms of the time it takes, ranging from hundreds to millions of years depending on the species and environmental factors. Evolution is a gradual process that occurs over generations as populations adapt to their changing surroundings through natural selection.
the Giant Anteater Myrmecophaga tridactyla, about 1.8 m (5.9 ft) long including the tail; the Silky Anteater Cyclopes didactylus, about 35 cm (14 in) long; the Southern Tamandua or Collared Anteater Tamandua tetradactyla, about 1.2 m (3.9 ft) long; and the Northern Tamandua Tamandua mexicana of similar dimensions.
