Tree Thinking Review
Draw a bracketed phylogenetic tree of the following groups on the next blank page:
• Peat Moss
• Capybara
•
Ostrich Fern
• Blobfish
• White Pine Tree
• Protists
• Escheria coli
•
Mexico Whiptail Lizard
•
Sunflower Sea Star
• Bold Jumping Spider
• T. Rex
•

that traits may have evolved more than one time.
• Chloroplasts
• Seeds
• Endosperm
• Flowers
• Vascular Tissue
• Mitochondria
Segmentation
• Central Nervous System
• Notochord
• Vertebrae
• Nucleus
• Membrane Bound Organelles
• Peptidoglycans
• Cranium
Fur
• Lactation

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 transferarrow_forwardC.

- Why are simpler structures considered ancestral when we study phylogeny? * 1 point Complex structures often evolve from simpler ones. Time element is a major consideration. The presence of a character state among some members of a lineage and an outgroup indicates that the character is ancestral. Simpler structures were more likely to be found in fossil records.arrow_forwardDesign 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.
