First, if genes are duplicated within a genome, the copies might come under the control of a new promoter. This could change the rules about when and how much a gene is expressed. Second, gene … Continue reading Biology from an Engineering Perspective

For Introduction to Evolution In chapter 6 of The Tangled Bank by Carl Zimmer, we learned that there is a simple equation to describe the rate of evolutionary change: Rate of evolutionary change = "heritability of trait" x "strength of selection" In the Rapid Evolution video, TREY the Explainer provides a couple of textbook examples. … Continue reading Rapid Evolution
Monkeys Carry Astroviruses of “Other Animals”
Submitted by Sydney Jennings This paper is a summary of the article, Non-Human Primates Harbor Diverse Mammalian and Avian Astroviruses Including Those Associated with Human Infections. The purpose of this paper was to explore the idea that Astrovirus (AstV) infections are species-specific, meaning that human Astroviruses (HAstVs) can only cause infection in humans and avian … Continue reading Monkeys Carry Astroviruses of “Other Animals”
