Our Position on Evolutionary Theory

Today's political climate regarding evolutionary theory suggests that departments committed to the highest standards of scientific integrity should honestly and openly state their position on evolutionary theory. As many science departments across the academic community have stated: We unequivocally support evolutionary theory, which has gained unwavering support by scientists who acknowledge that scientific validity comes only as a result of hypothesis testing, sound experimentation, and replication by others. It is this respect for the scientific method and scholastic integrity that has convinced the scientific community that evolutionary theory and the works of Charles Darwin and Alfred Russel Wallace are among the most important of our time. In short, we acknowledge that "Nothing in biology makes sense except in the light of evolution" (Dobzhansky 1973).

Charles Darwin and Alfred Russel Wallace are credited as having independently developed similar hypotheses to explain the divergence of species: a process of descent with modification. Darwin, 14 years Wallace's senior, was writing his research as a book when Wallace, seeking Darwin's approval, sent him a letter describing his hypothesis. Devastated that his life's work would be in vain, Darwin wrote to his close friend, the prominent geologist, Dr. Charles Lyell, "So all my originality, whatever it may amount to, will be smashed." The solution was to publish Darwin and Wallace's work jointly as "On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection."

Our Research

Hargrave Lab

The orangethroat darter (Etheostoma spectabile) is a common darter that consumes benthic grazing invertebrates affecting a stream primary productivity and creating a trophic cascade within an aquatic ecosystem.

Lutterschmidt Lab

A collaboration with Dr. Howard K. Reinert at the College of New Jersey to investigate habitat use of the Boa constrictor which has recently invaded the island of Aruba. Potential niche overlap could become a concern for the conservation of the endangered Aruba Island Ratttlesnake.

Choudhary Lab

Rhodobacter sphaeroides, a purple photosynthetic bacteria, whose genome has been completely sequenced and fully annotated.

T. Cook Lab

A gregarine (Nubenocephalus secundus) parasitizing the midgut epithelium of the blue-ringed dancer (Argia sedula). This is one of many new gregarine species described from an investigation for the biodiversity of these aquatic insect parasites.

Neudorf Lab

Parental feeding rates to nestlings are monitored at nests of Carolina Wrens as part of a study on parental investment strategies.

Gaillard Lab

A unicellular bi-flagellated alga (Chlamydomonas reinhardtii) is a model organism for studying the inctracellular signaling mechanisms that control movement of eukaryotic cilia and flagella.

Randle Lab

A genus of parasitic plants (Harveya)depends entirely on its hosts for water, minerals, and photosynthates. Such plants are of unique interest in molecular evolution and systematics.

Primm Lab

DNA electrophoresis showing the inserts in eight different (Escherichia coli) clones. We are cloning promoters from Mycobacterium smegmatis which are active in stationary phase..

J. Cook Lab

This neotropical hemipteran (Neoplea absona) in the family Pleidae was a specimen used to revise the genus. Pleids, or pygmy backswimmers, are predators of micro-crustaceans in stagnant waters.
