What does the trunk of the classic phylogenetic tree represent? single common ancestor pool of ancestral organisms new species old species
In a cladistic analysis, a systematist groups together organisms that share: derived homologous traits. derived homoplastic traits. ancestral homologous traits. ancestral homoplastic traits. all of the above.
Design an Experiment Imagine that you are trying to determine the evolutionary relationships among six groups of animals that look very much alike because they have few measurable morphological characters. What data would you collect to reconstruct their phylogenetic history?
What do scientists use to apply cladistics? homologous traits homoplasies analogous traits monophyletic groups
To construct a phylogenetic tree by applying the principles of parsimony to molecular sequence data, one would: a. start by making assumptions about variations in the rates atwhich different DNA segments evolve. b. group together organisms that share the largest number ofancestral sequences. c. group together organisms that share derived sequences, matching the groups to those defined by morphologicalcharacters. d. group together organisms that share derived sequences, minimizing the number of hypothesized evolutionarychanges. e. identify derived sequences by studying the embryology of theorganisms.
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. The late Miocene radiation of modern Felidae: A genetic assessment. Science 311:7377.
Where in a phylogenetic tree would you expect to find the organism that had evolved most recently? at the base within the branches at the nodes at the branch tips
Test Your Understanding Apply and Analyze 9. In interpreting a cladogram, (a) we can identify the specific ancestor of each taxon by tracing each branch back to the node closest to the root (b) taxa on the right side of a cladogram have evolved from the taxa on the left side (c) the relative placement of smaller branches allows us to determine the number of years since a particular taxon has evolved (d) we can determine relationships by tracing along the branches back to the most recent common ancestor (e) we must first identify horizontal gene transfer
What is the difference between micro- and macroevolution? Microevolution describes the evolution of small organisms, such as insects, while macroevolution describes the evolution of large organisms, like people and elephants Microevolution describes the evolution of microscopic entities, such as molecules and proteins, while macroevolution describes the evolution of whole organisms Microevolution describes the evolution of organisms in populations, while macroevolution describes the evolution of species over long periods of time Microevolution describes the evolution of organisms over their lifetimes, while macroevolution describes the evolution of organisms over multiple generations.
Match the terms with the most suitable description. ______ phylogeny a. similar across many taxa ______ cladogram b. evolutionary history ______ master regulators c. human arm and bird wing ______ convergent evolution d. present in a group but not in its ancestors ______ derived character e. based on neutral mutations ______ molecular clock f. insect wing and bird wing ______ analogous structures g. diagram of .sets within sets ______ divergent evolution h. different lineages evolve in a similar way ______ homologous structures i. closely related lineages evolve in different ways
What is used to determine phylogeny? mutations DNA evolutionary history organisms on earth
Imagine that you are a systematist studying a group of little- known flowering plants. You discover that the phylogenetic tree based on flower morphology differs dramatically from the phylogenetic tree based on DNA sequences. How would you try to resolve the discrepancy? Which tree would you believe is more accurate?
