Carl Linnaeus 14. synapomorphies 15. plesiomorphic and analyses Earth'sTRUE 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…

С. D. O a. The color on the tail fins of species B and C is best described as the result of evolutionary reversal. O b. The dorsal fin coloration seen in species A and C is likely due to convergent evolution. Oc. The presences of spots on species A and C is best explained by homology. O d. The color of the pectoral and pelvic fins in species A, B, and D is best explained by homoplasy. AMoving to another question will save this response. A. B.
- Question 2U Which is NOT an example of homoplasious characters? A More than one of these. B Bats and birds are both monophyletic groups with wings. Many species of insects, amphibians, and fish have evolved red and yellow warning coloration to advertise their poisonous skin or organs. Sharks and dolphins have fins and fuselage-shaped bodies, despite sharing a distant common ancestor. E) The amniotic egg is a synapomorphy of terrestrial vertebrates, but has been lost in many groups. Do you have additional content? You can add text, images, and files that support your answers.
