Fossils of a 160-million-year-old mammal found in China show us a placental mammal that is 35 million years older than any found before. This tiny animal is named Juramaia sinensis, or "Jurassic mother from China."
Although this discovery helps us fill in the blanks of mammals' evolutionary timeline, the reason for the split between placental mammals and marsupials is still a mystery. Link -via The Caudal Lure

With forepaws adapted to climbing trees, the newfound eutherian scurried about temperate Jurassic forests feasting on insects under the cover of darkness. This diet allowed J. sinensis to tip the scales at around half an ounce (15 grams), making the creature lighter than a chipmunk.
"The great evolutionary lineage that includes us had a very humble beginning, in terms of body mass," said Zhe-Xi Luo, a paleontologist at the Carnegie Museum of Natural History in Pittsburgh, who led the team that discovered the fossil.

I saw it happen live on TV.
That's the thing about statistics. Statistically speaking, unlikely things should sometimes occur, but people will always impute meaning to things which are meaningless. Which isn't to say that it isn't interesting.
Lottery numbers 04-15-23-24-35-42
LOST numbers....04-08-15-16-23-42
The odds in the article about two consecutive draws being the same do seem low. In a fifty number field/six number draw the odds of picking all six is 14 million to 1. So how does the two day/same numbers odds end up at 4 million to 1? It all seems strange to me, especially the fact that 18 people picked those same six numbers for the next draw. Who picks the complete set of numbers that just won?
There's a similar problem about how many people do you have to have in a room before there's a better than even chance of two of them sharing a birthday. Turns out to be around 23, not the 180 or so you might expect. The reason is there are a lot of possible birthdays, but most people think only from their own perspective - i.e. how many people share /their/ birthday, not how many people share /any/ birthday.
There's a Wiki page which explains the maths and which can easily be extended to the lottery figures.

Skipweasel, here's another way to think of it: Suppose there are 5 million possible number combinations in a particular lottery. No matter what combination of six numbers comes up one day, the numbers the following day have a one-in-five-million chance of being the same.
I suspect that the one mathematician's odds are off because, frankly,many if not most mathematicians know squat about probability calculations.
By the way, reports are that 3 of the same 6 numbers turned up in the NEXT drawing.
Random chance? I don't think so.
