Summary Introduction
To explain: The scientific inquiry of herbivore evolutions by adaptive radiation.
Introduction: The evolution of many species from a single ancestor is termed as adaptive radiation. It is a continuous process, where the diversification of species is in a common ancestral line. Species from a single ancestor can get fragmented into different subpopulations when isolated geographically and exposed to different environmental conditions. The species in a new habitat could establish their role in a new environment and become different from the common ancestor.

Show a phylogenetic tree that reflects the evolutionary relationships between the following taxa. All of the taxa should be on one (1) tree; var. stands for variety, a subspecific taxon (just as a genus can contain several to many species, a species can include several varieties).

Quercus rubra var. borealis northern red oak
Quercus velutina Black oak

- Consider why there might be natural selection for poisonous plants to warn potential herbivores with bright colors, but why there seems to be no similar selective pressure for poisonous mushrooms to do the same. Which of the following best explains this difference? a) Fungi, like mushrooms, do not rely on photosynthesis and hence do not need to attract or warn herbivores with bright colors. Plants have a symbiotic relationship with herbivores, which is not the case for mushrooms. Mushrooms are typically more toxic than plants, so there is no need for them to develop warning colors. Most of a fungus's body is the mycelium which exists underground, hence consumption of the above-ground mushroom cap represents a comparatively smaller fitness cost than for plants, whose vital photosynthetic structures can be consumed by herbivores.arrow_forwardCreate a hypothetical phylogenetic tree.arrow_forwardPhylogeny refers to the evolutionary descent of taxa. It refers to the relationship between ancestors and descendants and relationships among descendant taxa. It shows the lineage of taxa which can be summarized in a branching diagram called a phylogenetic tree.1.

- Green and brown algae share many common features. Both have pigments for trapping sunlight and use photosynthesis for energy. Both store their food as sugars. Both have cell walls and plant-like bodies. However, their DNA suggests that they are not even remotely related to one another.

The relationship between species richness and clade age in twelve groups. Question 7. One difficulty in estimating species richness is that many species have yet to be described. Suppose that the number of undiscovered species varies among taxa and that old clades tend to have more undiscovered species. In which direction would the observed relationship between species diversity and clade age be biased?

In constructing phylogenetic trees, it is useful to first draw up a character table to show the presence or absence of characters among the various groups of organisms being studied. a. Draw up a character table based upon the following shared derived characters of land plants: flowers, seeds, vascular tissues, and dependent embryos. Your character table must include the names/descriptions of the plant groups that are being characterized. b. Construct a phylogenetic tree based on this data.arrow_forward
