Evolutionary Biology in bite-sized pieces
By Kelly Bonnville If you’ve ever seen “Five Feet Apart”, a 2019 movie starring Cole Sprouse and Haley Lu Richardson, which tells the dramatic love story of two teenaged cystic fibrosis patients who can never be together due to their disease, you may be under the impression that cystic fibrosis mainly involves not being able … Continue reading “Cystic Fibrosis: A Heterozygote Advantage” – The Title of the Next Hit Movie
As someone who likes to play with fire in my cooking, I always have a hearty stock of chili peppers in my kitchen. Depending on the dish, I’ll use anything from canned chipotles, ground cayenne, and paprika to fresh jalapeños and habaneros. All peppers, hot and sweet, are cultivars of five species from the genus … Continue reading Bring on the Heat: The Evolution of Spiciness in Chilies
A recent examination of pelvises from human skeletons indicate migration patterns and climate may be responsible for global variation in birth canal size and shape. This variation likely represents neutral evolution by random chance and not necessarily the selection for pelvic adaptations, challenging long-held theories for human evolution and modern obstetric protocols. You might … Continue reading Global birth canal variation gives insight into human evolutionary past and modern obstetric practices
How do animals choose their mates? Dr. Maddie Girard and Dr. Damian Elias were pretty sure they knew what female peacock spiders found sexy—it had to be the red. Found throughout Australia, these tiny jumping spiders have excellent vision, and instead of a making a web, they sneak, climb, and pounce to catch their food. … Continue reading Seeing red in a new light: Peacock spider courtship defies our human assumptions
The craft beer movement gave rise to an immense diversity of brews. From porters and pale ales to dubels and dunkels, there is a seemingly infinite supply of tasty adult beverages to enjoy. Even within the ales, beer drinkers can choose among ambers, blondes, browns, coffees, and creams. Each of these brews is defined by … Continue reading Beer, snowflakes, and the origins of life
Life began in the water. Microbes swarmed around in primordial ooze, banded together to form multicellular organisms, and eventually grew complex enough to leave their watery homes and become the terrestrial animals that exist today. Some of those land-dwelling creatures became mammals, and in a surprising twist, three separate lineages of ancient mammals then returned … Continue reading 黑雷苹果模拟器全国首款ios模拟器_其他_吾爱次元资源网 ...:2021-7-23 · 老王的灯笼app - 1.9.9.1 清爽版 红杏出墙app_强大的上网神器 蓝灯二代app_去广告最新版本 sd女佣专业版破解版 - 4.15.1 中文已付费版 悟饭游戏厅免费vip作弊码破解版 - 4.2.0 最新版 绿叶“猥皮恩”上网神器_让上网更加快速！ 安卓虚拟定位精灵vip破解版 - 2.3.8
There is an entire community of pigeon collectors living amongst us. They marvel at the diversity of plumage, color, and patterning that this single species displays. In fact, none other than Charles Darwin himself fancied the pigeon species. These pigeon enthusiasts understand that we can learn a lot from pigeon diversity. In a recent publication, … Continue reading Lessons from the Urban Pigeon
A staple of warm summer nights, fireflies have charmed generations with their magical evening glow. Children setting out to capture them in jars can tell you the trick is to catch sight of each flash of light as the bugs fly around.

Today’s story begins with Peto’s paradox – the observation that larger animals should have higher cancer incidence than smaller animals, but don’t (1). Fundamentally, cancer is caused by DNA damage. Large animals have many cells and usually also have long lifespans. As a result, their numerous cells duplicate many times and are exposed to a … Continue reading Strength in numbers: extra copies of the TP53 gene helps elephants fight cancer
If it looks like an ant and walks like an ant, it must be an ant, right? Thanks to evolution, this isn’t always the case. Plants and animals can evolve to mimic other species in appearance, behavior, sound, or smell. By doing so, mimics can reap benefits such as increased access to food, enhanced reproduction, … Continue reading If you talk the talk, you’ve got to walk the walk: mimicry of ant locomotion in jumping spiders
