SCIENTIFIC INQUIRY
Herbivory (plant eating) has evolved repeatedly in insects, typically from meat-eating or detritus-feeding ancestors (detritus is dead organic matter). Moths and butterflies, for example, eat plants, whereas their "sister group" (the insect group to which they are most closely related), the caddisflies, feed on animals,

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?

- 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. Express some basic evolutionary relationships among groups of microorganisms, plants, and animals; 2. Illustrate the relationship of organisms with their environment; and 3.

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.

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_forwardExplain why plants being polyploid makes using the phylogenetic species concept difficult to use. Be sure to explain how the phylogenetic species concept attempts to classify organisms into distinct species. How can scientists still use the phylogenetic species concept to classify land plants, despite the majority being polyploid? (What do they do to get around this problem?)arrow_forward
