Directions: For the following organisms below, you are to sort them into at least 4 different groupings. There must be at least 2 organisms in a grouping. You may place them into columns (in a chart of some sort) or simply Number or your groups and list the organism that are included. ALSO, you must include a written description (at least 2 sentences) describing the characteristics of EACH GROUP that apply to all organisms within that group. Hint** A quick google search, or image search may provide you the visual data you need to categorize the organisms. Sponges (Porifera) Cnidarians (Cnidaria) Comb jellies (Ctenophora) Flatworms (Platyhelminthes) Ribbon worms (Nemertea) Nematodes (Nematoda) Arrow worms (Chaetognatha) Segmented worms (Annelida) Sipunculans (Sipuncula) Molluscs (Mollusca) Arthropods (Arthropoda) Bryozoans (Bryozoa) Phoronids (Phoronida) Lamp shells (Brachiopoda) Echinoderms (Echinodermata) Hemichordates (Hemichordata) Chordates (Chordata)

Please create a phylogenetic (evolutionary) tree given this criteria and follow all points! There are three domains of life - Bacteria, Archaea, and Eukarya. Start by drawing these three main branches. Then add branches for plants, animals, fungi, and protists. When adding all these branches, don't just add them randomly. The branching pattern reflects evolutionary relationships. You should use the relationships/branching patterns. Then add additional branches for • three species of bacteria • three species of archaea three species of plants three species of animals • three species of fungi • three species of protists (single-celled eukaryotes) You can pick any species you want. For each species, be sure to add 1 synapomorphy (shared derived character) that defines the species or group. • Finally, label the tree with all the terms (parts of a tree, not phylogenetic groups) when describing a phylogenetic tree.
For each combination of species, indicate whether the group they form would be monophyletic or paraphyletic. D < < A, G, B C, J, A, B, G, I, E, H, F A, B, G, I, H, E A D, C, A, B, G, K, J, I K B J | LL F H E 1. Monophyletic (i.e., a clade) 2. Paraphyletic (i.e., not a clade)
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…
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.

Explain your answer in some depth and avoid just saying "It is A" or It is B. Defend your answer and explain why you choice that answer choice. Question: Domestic dogs would least likely meet the definition of a single species using which concept? Group of answer choices A) Lineage B) Biological C) Morphological D) Domestic dogs are not a single species according to any of the species concept definitions.
Match the following phylogenetic group terms with their correct definitions: Monophyletic: A group that includes a common ancestor and all of its descendants Monophyletic: A group that includes a common ancestor but not all of its descendants Paraphyletic: A group that includes a common ancestor and all of its descendants Paraphyletic: A group that includes a common ancestor but not all of its descendants Polyphyletic: A group that includes a common ancestor and all of its descendants Polyphyletic: A group that does not include the most recent common ancestor of its members
