All the information you need is provided.
Use the Table here to construct a phylogenetic tree. You can upload a hand drawing and explain your reasoning or describe your tree using the
terminology from your homework (e.g. the outgroup would be....)
Use the morphological traits shown in Table A to construct a phylogenetic tree for plants (any
style of phylogenetic tree is fine). Be sure to clearly label all synapomorphies.
Table A. morphological traits of plants (X = trait possessed by plant)

2. The evolution of flowers from the fossil record appears to have been a very rapid event, dating back 130-140 million years ago. However, many
paleo-botanists think flowers probably evolved much earlier but for unknown reasons, are not seen in the fossil record. What might be three reasons
the fossil record may be inadequate in giving us the true evolutionary history of the flower?
3. Many paleobiologists estimate that 40% of species extinctions today are caused by non-native (or invasive) species introduction. Explain why
introducing a non-native species could attribute to such a large percentage of species extinction?
