Molecular Phylogeny: DNA Analysis and Biodiversity

The development of DNA and genetic analysis has opened up a whole new branch of biological investigation: molecular phylogeny. DNA analysis has been used to reclassify a great number of organisms. These ultra-sensitive techniques have been able to reveal previously imperceptible relationships between both living and extinct organisms.

Visit the Paleo-DNA Laboratory to learn a little bit more about DNA analysis. Examine the Biodiversity Services section to answer the following questions:

1. Why are wildlife biologists increasingly turning to DNA analysis for examining issues of biodiversity?
2, What are some of the implications of finding a low genetic diversity among a species?
3. Why would this information be useful for a scientist conducting research on an endangered species?

Solution Summary

Referring to the website and by responding to the questions, this solution examines aspects of DNA and genetic analysis, a new branch of biological investigation: molecular phylogeny. References are provided.
