Which of the following is NOT true about the Homo floresiensis fossil remains? Group of answer choices Were likely afflicted with a severe growth defects May have evolved from ancestors that left Africa before Homo erectus They were recovered in Liang Bua Cave on the island of Flores, east of Java have been affectionately named "the Hobbits" Were contemporary with modern humans 25 kya
Which of the following pieces of evidence would best support the argument that humans are more evolutionarily related to fish than they are to insects? All these organisms require oxygen to survive. The earliest fish fossils are found in the lowest strata of sedimentary rocks, followed by insects, and then humans. The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans. Fossils of ancient fish and human ancestors have been discovered in the same sedimentary rock layers.
Which of the following characteristics are indicative of primates only? homodont teeth post-orbital bar/closure heterodont teeth
The phylogenetic tree for 12 cat species (Felidae) reproduced at right was assembled from molecular sequence data. Which species is the domestic cats closest relative? Which clade is the sister taxon to tigers? Are bobcats more closely related to cougars or to ocelots? Source: From Warren E. Johnson et al. 2006.

Which of the following data sets is the one that scientists had to evaluate carefully since it made the artiodactyl phylogenetic tree less parsimonious? DNA sequence similarity between hippos and whales was the highest compared to other artiodactyls fossil evidence of animals that had traits of both whales and land mammals anatomical comparison between whales, other mammals, and fish presence of an astragalus bone in artiodactyls but not whales

How many total changes are required for each tree ? 2. Given your answer to question 1, which tree is a better supported hypothesis of evolution for these species ?
Which of the following is not an adaptive pattern of early African hominins? Group of answer choices Speciation was occurring quite frequently. Early hominin species had restricted ranges, thus it is likely they each exploited a small area allowing for rapid genetic diversification through genetic drift and natural selection and speciation. Most of the species appear to have been tied to desert-arid habitats. With the exception of early Homo, there are few evolutionary trends regarding increases in body size or encephalization. All of the early hominins show an ape-like developmental pattern.

Evolutionary microbiologists developed a theory about a common ancestor for all eukaryotic cells. Below is a model of the theorized changes during the origin of eukaryotic cells. Prokaryotes are not capable of phagocytosis, or engulfing outside particles by creating a pocket in the cell membrane. Engulfing of photosynthetic Photosynthetic prokaryote eukaryote Infolding of plasma membrane Prokaryote Engulfing of aerobic heterotrophic prokaryote Heterotrophic eukaryote Which of the following changes in early prokaryotes could be predicted to result in the emergence of eukaryotic organisms? the development of genetic transfer mechanisms in prokaryotes the evolution of predatory or parasitic relationships in prokaryotes the emergence of collections of cells functioning together in prokaryotes the expansion of internal structures to support larger individual cells in prokaryotes Time
In the past, the evolutionary history of whales was represented by cladogram A, shown below. As you can see, whales were believed to be closely related to mesonychids, an extinct group of mammals that looked similar to wolves. Today, that cladogram has been revised, as shown in cladogram B. Cladogram A Cladogram B Hippos Horses Hippos Whales Ruminants Pigs Camels Horses Mesonychids Time Time Which of the following statements best describes the reason for this change? Cladograms A and B are hypotheses that changed as new evidence became available. Cladogram B was revised to show a water-to-land pattern of evolution in groups of organisms. Cladogram B was altered to better include similarities in habitat as new information became available. Cladograms are organized today to show a much more simplified pattern like the one shown in cladogram B.
