The Latest Fossil Finds Make the Puzzle of Human Evolution Harder Than Ever to Solve
The Latest Fossil Finds Make the Puzzle of Human Evolution Harder Than Ever to Solve The latest molecular analyses and fossil finds suggest that the story of human evolution is far more complex—and more interesting—than anyone imagined By Bernard Wood
Blue Monkey Balls!
Yep. You read that right. And the picture confirms it. From the album: Timeline Photos By I fucking love science Across the animal kingdom, males can be brightly colored to attract females. Vervet monkeys also fall into this category, but only with their scrotums which are bright blue. However, this coloring comes with a catch:…
Economy of Scale
Giant Ant Colony Excavated, You won’t believe what they build underground! Although this story isn’t new by any means (October 2012 by Amazing Earth ), it shows what can be accomplished with one of the major transitions in Evolution: social living. Humans are not the only creatures that modify their environments or build on a…
Alga takes first evolutionary leap to multicellularity – life – 06 November 2013 – New Scientist
Alga takes first evolutionary leap to multicellularity – life – 06 November 2013 – New Scientist This is EXACTLY what we started talking about this week: one of the major transitions in evolution is considered to be the transition from unicellular to multicellular life. We discuss this with particular attention to dictyostelid slime molds (which…
Antibiotic Resistance and Drug Discovery
Antibiotic resistance is a topic we discuss in my class. With our current textbook, we mostly talk about ciprofloxacin and Campylobacter resistance, but there are many, many more examples, including drug-resistant strains of Pseudomonas, Mycobacterium, Staphylococcus, and lots more. Most people aren’t aware that the problem of antibiotic resistance isn’t new. Penicillin began to be used…
Using Google Maps to Follow Darwin
http://www.google.com/maps/about/behind-the-scenes/streetview/treks/galapagos-islands/ Last Friday, September 13, 2013, Google didn’t have a doodle. What it did have was a link under the search box to follow Charles Darwin’s voyage through the Galapagos archipelago. There are a couple of YouTube videos that give you an overview of what the project was about and what they did–and some of…
Evolution Is an Opportunist-By Wynne Parry and Quanta Magazine
Evolution is an Opportunist We just talked about theoretical models (and blue moon butterflies) in class, and how they help us make better scientific predictions and help us refine our understanding of, well, how stuff works. This article talks about using computer models (computational studies) about metabolism, and how they support the idea of evolutionary…
Signatures of rapid evolution in urban and rural transcriptomes of white-footed mice (Peromyscus leucopus) in the New York metropolitan area
I came across this article as I was starting a new project for my course in Evolution. A previous blog post has already dealt with the topic, but I wanted to expand on this and show how a news story doesn’t always cover everything about an article.
