Which of the following organisms would be most likely to fossilize? a rare flower O an abundant ovulate cone O an abundant pine tree needle O a rare pine tree needle

After the Great Dying, we enter the Era which covers the evolutionary history of the dinosaurs up until they go extinct. Cambrian O Mesozoic Paleozoic O Cenozoic

On this cladogram, the Kingdom Plantae (plants) is outlined in red. What is the "Charophyte green algae" considered to be relative to the plants? Charophyte green algae Mosses Ferns Gymnosperms Angiosperms Also a plant The ingroup The outgroup The basal taxon to the Kingdom Plantae The ancestor to the plants Clear my selection *

Part I: Construct a phylogeny Below is a list of seven hypothetical, currently-living species (A-G), and eleven of their character states (i.e., traits). You will use these traits to construct your tree. Species Character states green еyes green no no egg wings claws hair A scales tail carnivore teeth spots horns layer green eyes green no egg В scales wings horns tail carnivore hair teeth spots claws layer egg layer green green no no scales wings claws tail carnivore hair spots eyes horns teeth no no no egg no no scales red eyes wings claws layer no tail carnivore spots horns hair teeth no no egg layer no no E spots red eyes horns scales claws tail carnivore wings hair teeth no no no live no F spots red eyes wings claws carnivore tail hair scales horns birth teeth no no no live no G spots red eyes wings claws tail herbivore hair scales horns birth teeth Assume that the extinct ancestor of this group, at the root of the phylogenetic tree, had the following features: no spots, no scales,…

Which of the following phylogenies would be rejected as optimal by the parsimony criterion? Hypothesis II 1 Dark coat O 1 O 2 2 ܐܐܐ ܐܐܝܐ 3 Hypothesis I Dark coat 4 OR 1 Light coat 2 3 Light coat 4 1 2 Dark coat 3 4 TIME

To test evolutionary hypotheses, you make a phylogeny of a group of organisms based on six traits. You suspect tree dwelling evolved to allow for nest building A В 4 C 1 2 E F 5 3 2 1= singing 2= nest-building 3= short legs J K 4 4 = hollow snout M 5= crest 9- N 6=tree dwelling a) Based on your phylogeny, did tree dwelling evolve to allow nest building? Explain your answer. b) Your friend wants to put all of the species that have short legs into a single taxonomic group. Is this a good taxonomic group? Explain your answer. CO

35. The Eocene (54 – 35 mya) is the Cenozoic epoch associated with the   adaptive radiation of angiosperms, flying insects, and primates.   "heyday" (adaptive radiation) of prosimians.   adaptive radiation of anthropoids.   adaptive radiation of hominoids.   emergence of the earliest hominids.
