- When constructing phylogenetic trees, what is the purpose of applying maximum parsimony? Parsimony allows the researcher to "root" the tree. For trees based on morphology, the most parsimonious tree requires the maximum evolutionary events. The outgroup roots the tree, allowing the principle of parsimony to be applied. For trees based on morphology, the most parsimonious is the one that uses the simplest explanation of evolutionary events.arrow_forwardA phylogenetic tree is a branching diagram that shows the evolutionary relationship among different biological species or genes or organisms from a common ancestor. They are used as a research tool in various fields. All of the provided statements are true regarding phylogenetic trees, except? It is considered as a hypothesis of the evolutionary path. It is a tool that shows the evolutionary pathway. It shows evolutionary history through common ancestors. It shows only the phenotypic similarity.arrow_forwardCompare and contrast the neutral theory of evolution and the Darwinian (i.e., selectionist) theory of evolution. Explain why the neutral theory of evolution is sometimes called non-Darwinian evolution.arrow_forward
- Define homology and homoplasy and explain their connection to the concept of parsimony in phylogenetic analysis. Provide an example of each and discuss the challenges they may present when inferring evolutionary relationships.arrow_forwardBriefly discuss the differences in how a selectionist (one that believes that Natural Selection is a strong evolutionary force) and a neutralist (one that believes that genetic drift is a strong evolutionary force) views the following: molecular clock, evolution of coding sequences, evolution of "pseudogenes".arrow_forwardDescribe mutations that do not affect protein structure or function and provide details of how such mutations may play a role in evolutionary change and speciation. Give a specific example (including both the phenotypes and mutation)arrow_forward
- Does the use of DNA sequences in the study of evolutionary relationships mean that other characteristics are unimportant in such studies? Discuss what other forms of evidence you may still want to use, along with when and why those other forms of evidence would be especially helpful.arrow_forwardDiscuss at least two reasons why we cannot consider evolution by natural selection progressive.arrow_forwardThe biological species concept is based on the assumption that species are reproductively isolated and do not share genes. And yet a number of organisms that are considered different species hybridize (mate and exchange genes). Hybridization between different species is more common in plants than in animals. Propose some possible reasons for this difference.arrow_forward
- Charles Darwin’s claim, that the species level of classification is just as arbitrary as that of any other taxonomic level, is supported by all of the following observational failures except: the inability of a sexually-reproducing eukaryotic species to interbreed with a different species the inability of a cloning species lacking biparental reproduction to interbreed with a different species the inability of an asexual eukaryotic species to interbreed with a different species the inability of an extinct species (like a dinosaur) to interbreed with a different species the inability of a prokaryotic species to interbreed with a different species.arrow_forwardA scientist is attempting to build a cladogram that shows the evolutionary closeness of three organisms in relation to humans. After doing DNA analysis, they determine that the organisms share the following percentages of DNA: Organism A and humans share 85% of their DNA. Organism B and humans share 80% of their DNA. Organism C and humans share 90% of their DNA. Based on this information, which order should they go on the cladogram (from least related to most related)?arrow_forwardCharles Darwin’s claim, that the species level of classification is just as arbitrary as that of any other taxonomic level, is supported by all of the following observational failures except: the inability of a cloning species lacking biparental reproduction to interbreed with a different species the inability of an asexual eukaryotic species to interbreed with a different species the inability of a sexually-reproducing eukaryotic species to interbreed with a different species the inability of a prokaryotic species to interbreed with a different species the inability of an extinct species (like a dinosaur) to interbreed with a different speciesarrow_forward
