The study featured in "This is a Truly Lousy Experiment" relied on well-establishedconclusions from the classic research of Charles Darwin. From the article, Darwin's researchon evolution by natural selection was based on the rationale:If artificial selection by breeders could generate diversity in only a few generations ofpigeons, then it would not be surprising that nature would be capable of generating thevast diversity of organisms found on earth.O If natural selection by breeders could generate diversity in only a few generations ofpigeons, then it would not be surprising that artificial selection over a very long time,would be capable of generating the vast diversity found on earth.If artificial selection by nature could generate diversity in only a few generations ofpigeons, then it would not be surprising that breeders, over a very long time, would becapable of generating the vast diversity found on earth.Charles Darwin did not study diversity and evolution.If artificial selection by nature could generate diversity in only a few generations ofpigeons, then it would not be surprising that breeders would be capable of generating thevast diversity found on earth.

Vhy was natural selection controversial to biologists in Darwin's time? It was a cruel and unfair principle as to why species change. B) It went against the religious beliefs of the time. There was no evidence that descent with modification during Darwin's time. He had no explanation for how advantageous traits were passed from parent to offspring.
Offically speaking, did Charles Darwin develop the theory of "evolution" or the theory of "descent with modification?" I know he coined the second term but I can't find if that's all he's historically creditited with.
Most new mutations are detrimental, yet rare beneficial mutations canbe adaptive. With regard to the fate of new mutations, discuss whetheryou think it is more important for natural selection to select againstdetrimental alleles or to select in favor of beneficial ones. Which doyou think is more significant in human populations?
The dog breed West Highland Terrier is a product of artificial selection. Give a brief description of the breed and its desired traits. What wild ancestor did it come from? Was it produced with selective breeding or genetic engineering (i.e. genetically modified)? What are the benefits of artificial selection in this case? Are there potential negative consequences?
In lecture we discussed eight (8) lines of evidence that Darwin used to lay out his argument for the fact of evolution in his book On the Origin of Species (1859). Using your materials from lecture and the last chapter of the "Origin" that we read for section, 1) rank order these lines of evidence based on what you find the most to the least compelling. 2) Be sure to describe each of these lines of evidence and 3) discuss how they are, or not, relevant in the early 21st century. (From old pset1) Evidence Variation in domesticated species and breeding (artificial selection) Hierarchical classification (groups nested within groups) "Unity of type" - modification of the same basic structure (homology) Evident "fit" of organisms to environments (but imperfections) (adaptation) Structures without apparent function (vestigial structures) Similarity of organisms in early phases of development (embryology) Order in diversity through time in the fossil record (paleontology) Order in…
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?
Lamarck was an early naturalist who published his own ideas about species changing over time. He, however was mistaken about one critical aspect of evolution. If you could travel back in time what advice would you give Lamarck to correct his misunderstanding? Tell him that species actually do change and evolve over time Tell him that traits acquired during an organisms life are not passed on to offspring Tell him that artificial selection does not lead to new varieties of plants and animals Tell him that characteristics are heritable: Parents do pass on their characteristics to their offspring
Choose an organism that is a product of artificial selection. Give a brief description of your organism and its desired traits. What wild ancestor did it come from? Was it produced with selective breeding or genetic engineering (i.e. genetically modified)? What are the benefits of artificial selection in this case? Are there potential negative consequences?
Natural history museums house collections of many kinds ofanimals. These collections contribute to our understanding ofevolution. Most museums still participate in limited collecting,concentrating on particular groups or organisms that will provide aparticular insight into evolution. A bird that was suspected of beinga rare hybrid recently appeared in Missouri, so it was collected forstudy at a nationally recognized museum. Some members of thelocal bird-watching community were upset. a)Do you think that collecting birds such as this suspected hybrid is scientifically justified? Why?
Microevolution is defined as a change inallele frequencies in a population over generations. Please explainwhat an allele is, in genetic terms. Name the three major factorsinvolved in allele frequency changes in populations. Describe, indetail, how natural selection works on individuals, while evolutionoccurs in populations. Include a real or hypothetical example ofthe process of natural selection in your answer other thaninsects and insecticide! Identify the specific natural selectionpressure and the specific trait being selected for in yourexample.
In a population of lizards, color is genetically determined. The current population has two two phenotypes: blue and yellow. Which of the following scenarios could result in evolution by migration? O A disease indiscriminately reduces the population by 90%. Birds are better able to see and therefor prey on blue lizards The population is joined by individuals from a nearby population that has an allele for a red phenotype. Females preferentially mate with individuals exhibiting the blue phenotype.
using venn diagram, give similarities and difference of two theories (Natural Selection and Artificial Selection)
