5:16 PM | Imperfect generalism in Darwin’s finches
[ This post is by Luis Fernando De León; I am just putting it up. –B. ]How species coexist in nature is one of the long-standing questions in evolutionary ecology. This is particularly relevant for understanding the process of adaptive radiation, which is thought to explain a large portion of the Earth’s biodiversity.Adaptive radiation often results in a large number of coexisting, closely-related species that share (or compete for) similar resources, environments, or […]

3:07 PM | That's a lot of stars; That's a lot of galaxies
Unless you've had a chance to get away from civilization, way away from civilization, you don't really know what the night time sky looks like because of light pollution. Years ago TPP found himself in the outback of northern Queensland at a quaint place called the 40-mile Scrub. So no lights, no clouds, no humidity, and it was amazing what you could see of this unfamiliar night sky. The scope of our galaxy and the universe it occupies is quite mind-boggling, the more so that this is […]

2:33 PM | Talk for UC Davis Pre-Health Meeting (#UCDPHSA): Opening up to Diversity
Sunday I gave a talk at the "12th National UC Davis Pre-Health Student Alliance Pre-Medical and Pre-Health Professions Conference".  I normally try to not give talks on weekends (to spend time with my family) but I made an exception here since this meeting has a strong commitment to issues relating to diversity in health and STEM fields.  This mission statement for the meeting reads:The UC Davis Pre-Health Student Alliance’s objective is to introduce and support academic, […]

12:32 AM | POTW 6
If you’re in the mood, go have a look at the new Problem of the Week. It’s a Shakespeare-themed alphametic this week, with bonus sonnet! It’s a bit more challenging than last week’s problem (a solution to which has now been posted at the above link), but still doable if you look at it right.…

12:21 AM | Sunday Chess Problem
The Spetember 2014 issue of The Problemist showed up in my mailbox this week. That’s the official magazine of the British Chess Problem Society, as I’m sure you’re aware. It included the problem below. It’s one of those delightful compositions that makes you wish you had thought it of it yourself. It was composed by…

7:59 PM | Bickerton: Round Two
A few years back Derek Bickerton published a book called Adam's Tongue which I reviewed in three posts (here, here and here). That book was disappointingly breezy, a lively account that made bold assertions and brushed objections aside with the...

2:02 PM | Human-made climate change, or climate change made humans?
We hear a lot in the news about accelerated climate change due to human activity, and for very good reasons. Just have a glance at the first half Intergovernmental Panel on Climate Change’s 2014 report (IPCC 2014 Summary) if you want to know how we’ll all be affected by climate change in our own lifetimes.

On July 3, 1754, colonial lieutenant Colonel George Washington fought and lost a small battle on this site in southwestern Pennsylvania. He and his 400 men had built this makeshift fort about a month before in anticipation of an attack by several hundred French soldiers and their Indian allies. The French were incensed at Washington […]

6:00 AM | Lazy analysis – inequality edition
Over at WSJ Real Time Economics, Josh Zumbrun turns the following chart into a claim that “the SAT is just another area in American life where economic inequality results in much more than just disparate incomes.” But what does the chart actually tell us? In a perfect meritocracy, the smartest students will score the highest. […]

Originally posted on Science Post:Conventional estimates for the collapse of the Aegean civilization may be incorrect by up to a century, according to new radiocarbon analyses. While historical chronologies traditionally place the end of the Greek Bronze Age at around 1025 BCE, this latest research suggests a date 70 to 100 years earlier. Archaeologists…

4:07 PM | When is a pumpkin not a pumpkin?
TPP knows where the pumpkin capital of the USA is located.  Morton, a little town right here in Lincolnland. And very few pumpkins are grown there. The reason for this is that the jack-o-lantern pumpkin is not the pumpkin of pies, and it never has been. Usually the news media get this wrong, so what a surprise to read a correct and well-informed article about pumpkins, in the HuffPo!  Jack-o-lantern pumpkins are a very watery fruit, not as watery as a tomato, but watery none the […]

Links this week: Plenty of press and interesting articles sparked by Peter Thiel’s new book. First, he has a swipe at business schools. And some great one-liners. But is he wrong about the future? Another tech-billionaire – Elon Musk wants to put people of Mars. But he doesn’t need one million people to get enough […]

5:46 AM | Responses to Barash’s Talk
Recently I discussed an essay by David Barash that appeared in The New York Times. Barash discussed a talk he gives to his animal behavior class about evolution and religion. More specifically, he explains why, in his view, evolution and religion are just incompatible. I mostly agreed with the substantive points that he made, but…

5:25 AM | Wooster’s Fossil of the Week: An early bryozoan on a Middle Ordovician hardground from Utah
Last week I presented eocrinoid holdfasts on carbonate hardgrounds from the Kanosh Formation (Middle Ordovician) in west-central Utah. This week we have a thick and strangely featureless bryozoan from the same hardgrounds. It is very common on these surfaces, forming gray, perforate masses that look stuck on like silly putty. Above you see one on […]
