Both Darwin and Wallace, while observing life on islands, concluded that natural selection is the mechanism for biological evolution. The Hawaiian and nearby islands once had at least 30 species of honeycreeper birds and lived nowhere else on earth. Natural section occurs everywhere in all species. What characteristics of islands allow the outcome of natural selection to be so obvious?

Which of the following is not true of natural selection? (a) natural selection acts to preserve favorable traits and eliminate unfavorable traits (b) the offspring of individuals that are better adapted to the environment will make up a larger proportion of the next generation (c) natural selection directs the course of evolution by preserving the traits acquired during an individuals lifetime (d) natural selection acts on a populations genetic variability, which arises through mutation (e) natural selection may result in changes in allele frequencies in a population
Darwin proposed natural selection as a mechanism for evolution. How is it similar to artificial selection? How is it different?For natural selection to work, there must be genetic variation within a population as well as mutations? Why must there be both?
One of the lines of evidence that led Darwin to the theory of natural selection was his study of artificial selection. Plant breeders and pigeon breeders select offspring with specific traits in mind beforehand. a) However, since humans are an integral part of the natural world, do you think that artificial selection might be more appropriately termed “natural selection”? Why?
What did Darwin’s travels reveal to him about the number and variety of living species? How did tortoises and birds differ among the islands of the Galapagos? What is evolution? Why is referred to as a theory? Darwin found fossils of many organisms that were different from any living species. How would this finding has affected his understanding of life diversity?
What are some of the ways that Darwin's theory of natural selection played out in human evolution? Can you see evidence of particular adaptations as our ancestors evolved, speciated, and in some cases went extinct?
While the French biologist LaMarck was correct in proposing that evolution does occur, he believed that the long necks of giraffes evolved as generations of giraffes reached for ever higher leaves on the trees. Using these observations, LaMarck proposed the theory that evolution occurs due to the inheritance of characteristics acquired during an organism’s lifetime. From what you know about the scientific method, why is this incorrect?
While hiking in the andes mountain in south america, darwin found a glyptodon fossil that resembled the modern armadillo. This evidence was used by Darwin to support his theory of natural selection by showing how species have..
Which of the following is NOT a characteristic of natural selection? a) Variation exists among individuals in a population b) Some individuals are better adapted to their environment than others c) Organisms evolve to fit a predetermined goal or plan d) The better-adapted individuals are more likely to survive and reproduce
What was missing in Darwin’s explanation of evolution by natural selection? How does the modern synthesis fill this gap?
A population of birds lives on a mountain. In this population, there are red-winged birds, orange-winged birds, and blue-winged birds. A predatory snake eats more of the blue-winged birds because they are not well camouflaged on the red and orange plants that grow on the mountain. This is an example of which mechanism of evolution? Group of answer choices Gene flow Cryptic coloration Natural selection Sexual selection Genetic drift
Darwin observed that all organisms show variation. Is there any population of organisms that is an exception?
The most important evidence that Darwin used to develop his theory of natural selection came from ___. his boyhood neighborhood in England the Galapagos Islands Australia & New Zealand the Argentine pampas South America
