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

Triazines are a group of chemicals used to kill weeds in the field, such as pigweed and kochia. However, in late 1970s and early 1980s, resistant plants were found that are resistant to triazine applications. Which of the following statements is correct? -The appearance of triazine resistance is the result of mutation. -The spread of triazine resistance in the field is the result of natural selection. -Even if farmers have not used triazines, there would still be individuals with triazine resistance in the field, albeit at a much lower frequency. -All the statements are correct.
Which of the following are supported explanations for the evolution of complex traits? A) incremental changes each providing a benefit B) a trait origiannly selected for a specfic function adopts a new function as a consequence of selection
Read in the Introduction about the three kinds of natural selection: directional, stabilizing, and disruptive. In Procedure 9.1, the phenotype we are considering is size. Which one of these types of natural selection do you expect to see if your answer to question 1 above is correct? Explain.
Artificial selection is when people selectively choose individuals with a certain desired trait to use as parents of the next generation. It is done to domesticated (or semi-domesticated) organisms. It has produced such monstrosities as bubble-eyed goldfish, revealing the potential for selection acting on heritable variation to produce varieties appearing very different than their ancestors. How is that different from natural selection? (Select all that apply) A- In artificial selection, humans directly cause new mutations to occur, whereas natural selection relies on mutations that occur randomly over time. B- Artificial selection can lead to organisms that would be unfit to survive in the wild, whereas natural selection usually makes the population better adapted. C- Artificial selection is directed ahead of time towards an intentional goal; not so with natural selection. D- Really, they are exactly the same process. Both cause what seems to be design without a designer. E-…
What is the difference between evolution, natural selection, and artificial selection? A. Evolution is a genetic change in a population over time which can occur through natural selection. Artificial selection is the differential reproduction of individuals in a population to promote the characteristics chosen by the breeder. B. Natural selection is the change of allele frequencies in a population over time. Evolution leads to differential survival and reproduction of individuals. Artificial selection has produced domesticated animals and plants. C. Evolution is a mechanism of artificial selection. Natural selection is a form of artificial selection in which nature selects the characteristics that are most beneficial to a species. D. Artificial selection is a mechanism of evolution and is the main process of domesticating animals and plants for human use. Natural selection is the same as evolution.
Which of the following statements best characterizes genetic diversity in humans? 1.) There are far more genetic differences between populations/groups than there is variation within populations. 2.) Between-group differences in most phenotypic traits (e.g., athletic ability, performance on standardized tests, etc.) are mostly inherited and due to the effects of natural selection. 3.) The vast majority of polymorphisms (such as SNPs) in the genome are informative about a person's ancestry (in other words, you could get a pretty good idea of someone's ancestry by looking at their genotype at just about any random SNP in the genome). 4.) Humans have much lower levels of genetic diversity than most other animals.
You study a group of wombats for your honours thesis. You find in your very large population samples a non-synonymous mutation at intermediate frequency (p = 0.45). After years of work, you find that both alleles (the mutant and the non-mutant) are maintained in the population. Whose theory is your %3D work MOST CONSISTENT with? The Balance School of Ford and Dobzhansky Lamarck's inheritance of acquired characteristics Haldane's theory on mutation-selection balance Kimura's Neutral Theory
