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. rubra Red oak
Quercus rubra var. borealis northern red oak
Quercus velutina Black oak
Fagus grandifolia Beech
Castanea dentata American chestnut
Castanea pumila var. pumila Chinquapin

- The Swedish botanist Carolus Linnaeus was the first taxonomist to argue that, contrary to Aristotle: humans and horses should be classified in the same kingdom (Animalia) humans and apes should be classified in the same order (order Anthropomorpha, or Primates) humans and goats should be classified in the same kingdom (Animalia) humans and cats should be classified in the same order (order Anthropomorpha, or Primates) humans and dogs should be classified in the same kingdom (Animalia)arrow_forwardMake phylogenetic tree with this organisms: Gray whale,Ginger, Peacock, Tiger, Rice, Cat, Pineapple, Crocodile, Box jellyfish, Bambooarrow_forwardCreate a hypothetical phylogenetic tree.arrow_forward
- Phylogeny 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.

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.

- Phylogenetic trees are used to show the evolutionary relationships among various biological species and are usually based upon shared derived characters. 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_forwardDiagram Analysis Study the phylogenetic tree below and explain the phrase, “Man and ape, regardless of the sub-species of ape, shared more than the air they breathed”arrow_forwardYou can use plants grown in pots in a growth chamber to investigate many ecological and evolutionary research questions. Identify an interesting ecological or evolutionary research question, then design an experiment to address this question using a plant system. To come up with your research question, think of questions related to topics covered in lecture. The following questions are very general, but might give you some ideas as you develop your own, more specific, question.• Which species in a group of species is the best intraspecific competitor?• Which species in a group of species is the best interspecific competitor? • Is the best intraspecific competitor also the best interspecific competitor?• Does competitive exclusion occur between two species with similar ecological niches?• Does the outcome of interspecific competition change in different environments, or is the best competitor always the best competitor under all environmental conditions?• Similar to the question above –…arrow_forward
