In a phylogenetic tree, what might a polytomy represent?
|
Lack of knowledge about the relationship between species. |
||
|
Rapid speciation in which multiple species emerged at the same time. |
||
|
Extinct species because a polytomy indicates the lineage is now extinct. |
||
|
Both A and B |

Which of the following provides the strongest support that a proposed phylogenetic tree is an accurate reflection of the real genealogical relationships among a set of species? a. Phylogenetic methods applied to multiple, independent sources of evidence (e.g. comparisons of independently evolving genes, or comparisons between DNA-based analysis vs. morphological analysis) provide support for the same evolutionary tree b. The phylogeny was based on the Maximum Parsimony method applied to DNA sequence data for lineages with high rates of evolution...

1. If you were to build a phylogenetic tree of living animals,
which of the following derived characters would appear first?
A. deuterostome development
B. true tissues
C. protostome development
D. bilateral symmetry
2. Birds and mammals are endotherms. They maintain body
temperature by producing heat through metabolism. Endothermy is
energetically expensive for an organism, yet endotherms have become
the dominant group of tetrapods. What is a major evolutionary
advantage of endothermy?
A. Endothermy allows greater independence from water.

While there is no absolute time on this cladogram, there is relative time running from left to right (right is more recent). Answer the following questions about this tree. Afrosoricida - Macroscelidea Tubulidentata Proboscidea Hyracoidea Sirenia Xenarthra Dermoptera 1. Monotremes (Monotremata) are the only mammals (extinct or extant) that do not give live birth.
