This Evolution 101 post is by MSU grad student Thassyo Pinto The ownership of goods such as luxury cars, expensive boats and conspicuous consumption, and showing it off to others, transmits a signal informing that owner is capable of bearing expenses. … Continue reading
This post is by MSU Postdoc Sarah Fitzpatrick working at the Kellogg Biological Station Consider a native fish population in a small headwater stream with low genetic diversity due to genetic drift and founder effect (loss of variation that occurs when … Continue reading
BEACONites Bjørn Østman and Randy Olson created a video to visualize evolution in action using fitness landscapes. Read about it below! Fitness landscapes were invented by Sewall Wright in 1932. They map fitness, or reproductive success, of individual organisms as a function … Continue reading
This week’s BEACON Researchers at Work post is by MSU graduate student Raffica La Rosa. Novel traits differ qualitatively from the characters from which they arise, and are generally thought to be adaptive. I study adaptive novel traits by combining … Continue reading
This week’s BEACON Researchers at Work blog post is by MSU postdoc Noah Ribeck. We are all taught the basic tenet of evolution by natural selection: occasionally an individual is born with a mutation that improves its chances of having … Continue reading
This blog post is by MSU graduate student Mike Wiser. Many things in life seem to follow the Goldilocks principle: both too much and too little of something can be worse than striking a balance somewhere in between. Goldilocks saw … Continue reading
This week’s Evolution 101 blog post is by MSU postdoc Arend Hintze and MSU graduate student Randy Olson. While fitness landscapes are generally thought to be more of a theoretical construct, they are in fact quite tangible and underly every … Continue reading
This week’s Evolution 101 post is by MSU postdoc Bjørn Østman. Bjørn also blogs at Pleiotropy. What is epistasis? Epistasis is a measure of the strength of epistatic interactions. Epistatic interactions are non-additive interactions between alleles, loci, or mutations. That is, … Continue reading
This week’s Evolution 101 blog post is by MSU graduate student Emily Weigel. This is a moment to thank your mom. Mothers have more of an effect on their offspring than one might first think. In addition to the DNA, … Continue reading
