Chapter 1: Introduction to Biological Diversity 2. What does the phylogenetic tree in Figure 2 indicate about the evolutionary relationships of the leopard, striped skunk, and wolf? Mephitis mephitis (striped skunk) Panthera Lutra lutra Canis familiaris (domestic dog) Canis Species pardus (leopard) (European otter) lupus (wolf) Genus Panthera Mephitis Lutra Canis Family Felidae Mustelidae Canidae Order Carnivora Figure 2 The connection between classification and phylogeny

Hello, I need help answering number 5 questions using the phylogeny below pls & thank you! 5.a) In the 1990s, when only mitochondrial DNA sequencing was available, geneticists claimed that there was no hybridization between humans (Homo sapiens) and Neanderthals (Homo neanderthalensis). Does the phylogeny shown above support the claim humans did not hybridize with Neanderthals in the past? How can you tell? b) Once nuclear DNA sequencing became fast and able to handle sequencing ancient DNA, living humans were found to have some Neanderthal genes. Is this finding clear evidence that some early modern humans did indeed hybridize with Neanderthals? Why? c) Did female H. sapiens hybridize with Neanderthal males to produce fertile offspring that then back-crossed with modern humans? What does the graph say about this? d) Did male H. sapiens hybridize with Neanderthal females that then back-crossed with modern humans? What does the graph say about this? Picture reference:…

Directions: Read each question carefully and choose the letter of the best answer. 1. A phylogenetic system that defines groups by distinguishing between ancestral and derived characteristics. A. Cladistics B. Cladogram D. Taxonomy B. Phylogenetic tree 2. Traits that are old and have been retained from a common ancestor is called? A. Ancestral trait B. Derived trait B. Dichotomous trait D. Scientific trait 3. Based on Dichotomous key which one is Not correct? A. A dichotomous key is a method of identification whereby groups of organisms are divided into two categories repeatedly. B. The key branches split in two at each stage, it is called a dichotomous (from the Greek dicho meaning "in two" or "split" and tom, meaning “to cut") key. C. A tool that allows the user to determine the identity of items in the natural world, such as trees, wildflowers, mammals, reptiles, rocks, and fish. D.

Quiz Active 2 3 4 Why was modern classification invented? O Traditional classification could not classify all living things. Scientists realized related organisms do not share similar characteristics. Scientists understood that species share a common ancestor O Modern classification is faster and easier to use. 5.

TRUE OR FALSE 1. The science of cladistics produces a system for naming and classifying organisms. 2. The broadest categories in the system of classification, bellow kingdom level, are called phyla. 3. The only taxonomic unit that is needed to be written in entirely lower case letters are the genus level. 4. When all the organisms in one taxon comes from a single common ancestor, the taxon is considered to be monophyletic. 5. The presence of opposable thumbs in humans and other apes means that we share a common ancestor; this character shows homology. 6. When a derived character is shared by members of the clade, the process is called a symplesiomorphy. 7. Sexually and asexually reproducing organisms which includes polyphyletic groups are known as the phylogenetic species concept. 8. Sympatric speciation occurs when the formations of new species happen in the same geographic area. 9. When a tree is unrooted, it is not necessary needed to have an outgroup. 10. Derived characters are…

Identify the type of evolution being described.

Topic: Role of Molecular Biology in Evolutionary Classification How does the recently developed DNA technology help scientists establish a more accurate classification scheme? Information on DNA can often indicate relatedness between organisms and even provide data on how long they have been evolving separately. Discuss the influence of DNA and molecular biology on the future of evolutionary classification.

QUESTION 2 What traits are used to place organisms into Linnaeus's Taxonomy? anatomical features, the fossil record, reproductive habits, genetic data. appearance, behavior, size, color. geographical location, number of individuals in the population, food source, behavior. habitat, ecosystem, climate, geology.

Mon Aug 6:45 A Relaunch to update Animal Diversity Lab Activity: For this lab activity, you will create a phylogenetic tree with 20 Sponge Bob Characters and 35 different "shared derived characteristics" for members of the Animal Kingdom. Note if there are any instances of convergent evolution in these characteristics. You can do this activity ANY WAY you want. Your tree can be made by drawing it by hand or by creating it in Powerpoint, Canva, or by sorting and connecting the Spongebob PDFs in a large space and taking a photo.

PLEASE help! Thanks! Morphological data can sometimes be misleading in terms of evolutionary relationships. Question: Why can morphological data be misleading? Think about convergent evolution/ environment and the whale, dolphin, hippo relationship)

What Have I Learned So Far? Write True if the statement is true. If false, change the underlined word or phrase to make the statement true. 1. Charles Darwin coined the term “survival of the fittest." Fossils can be used in determining the remains of ancient organisms. 2. 3. Geology is the study of the distribution of plants and animals on Earth. 4. Lamarck proposed the theory of use and disuse. 5. Genetic mutation accounts for evidence of evolution. 6. The theory of acquired characteristics is the concept of Wallace. 7. Vestigial organs are structures that have a particular use before but have no particular purpose for existing animals. 8. The similarities of the embryos of vertebrates indicate a common ancestral domain among them. Biochemical evidence does not provide a solid proof of evolution. 9. 10. Anatomy of animals can be used as evidence of evolution Biodiversity and Systematics: Evolutionary Relationships 179

Please just solve question 5, thanku! 2.Clades can be described as "natural groups."Why do you Bthink this is so？ 3.What do the“tips"and“branches"of a phylogenetic tree represent？ 4.Describe how you“trace ancestors back through time"on a phylogenetic tree. 5.Compare and contrast traditional and phylogenetic classification systems. (a）What are the advantages and disadvantages of each？ (b)Think of an example of when it would be useful to use a traditional classification.Why would this system be the best choice in this case？ (c)Think of a situation where it would be useful to use phylogenetic classification system.Why would this system be the best choice in this case？ 6. Traditional and phylogenetic classification systems usually place species in the same groups. For example，both systems place lions and tigers together，and horses.

Student Handout Module 1: Ecomorphs 1. At the beginning of the virtual lab, you were asked to sort eight lizards into categories. What criteria did you initially use to make your groups? Did you revise your criteria later? Why? 2. An adaptation is a structure or function that is common in a population because it enhances the ability to survive and reproduce in a particular environment. Provide one example and an explanation of one adaptation in the Anolis lizards. 4. What is an ecomorph? Provide one example from the virtual lab. 3. Provide one evolutionary explanation for why lizards living in the same part of the habitat (i.e., grass) would have similar characteristics. 5. How is an ecomorph different from a species? 6.
