The Devolution of Evolution
Leonid Moroz | Nov 1, 2010 | 4 min read
By Leonid Moroz The Devolution of Evolution Why evolution and biosystematics courses must be included in all biomedical curricula. Nearly 40 years ago Theodosius Dobzhansky wrote: “Nothing in biology makes sense except in the light of evolution.” How is it, then, that so few newly minted PhDs in the biological sciences have taken any formal graduate school courses in evolution or biodiversity? This fosters a knowledge gap that can become difficult t

Do Epigenetic Changes Influence Evolution?
Katarina Zimmer | Nov 1, 2022 | 10+ min read
Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated.
Indiana Molecular Plant Biologist Honored For Research On Chloroplast Evolution
Rebecca Andrews | Feb 3, 1991 | 2 min read
Jeffrey Palmer, an associate professor of biology at Indiana University, Bloomington, has been awarded the David Starr Jordan Prize in biology for his contributions to molecular plant evolutionary biology. The international prize, given jointly every three years by Stanford University, Calif.; Cornell University, Ithaca, N.Y.; and Indiana University, is named after a late 19th- and early 20th-century evolutionary scientist, educator, and university president with ties to the three institutions.
Proposed Deep-Sea Mining Zone Harbors Previously Unknown Species
