Researchers: Cooler climate helped penguins’ march through evolution

Published

on

Penguins waddled into the book of life around 20 million years ago and diversified thanks to global cooling which opened up Antarctica for habitation, a study said on Wednesday.

Scientists led by Sankar Subramanian of Griffith University in Australia sequenced telltale signatures of DNA from the genome of 11 penguin species that are alive today.

They compared these stretches to make a “molecular clock” — a way of calculating how species evolve on the basis of regular mutations in DNA.

By this yardstick, the forerunner of all penguins lived 20.4 million years ago, according to the paper, published in the British journal Biology Letters.

If so, penguins showed up more recently than thought. Previous estimates put their emergence at 41-51 million years ago.

Penguins then diversified around 11 to 16 million years ago to form most of the species that are around today, according to the study.

“This overlaps with the sharp decline in Antarctic temperatures that began approximately 12 million years ago, suggesting a possible relationship between climate change and penguin evolution.”

‘Washington is no longer functional’: Brian Williams admits he’s sad to report that ‘our government is broken’

Published

MSNBC anchor Brian Williams on Tuesday reported that America's federal government is broken.

"This was day 908 of the Trump Administration and while there is no joy in it, one way of summing up today is this: Our government’s broken, our politics are broken, Washington is no longer functional, and the cracks in our society are deepening," Williams reported.

"Much of this day was taken up by the discussion of racist statements by the president. Then tonight came the news that had so many people thinking back to when we were different, the death just tonight of retired Supreme Court Justice John Paul Stevens at the age of 99," he said.

Trump ignored being condemned by Congress and instead praised Republicans on Twitter for defending his racism

Published

President Donald Trump celebrated on Tuesday night despite the House of Representatives having voted earlier in the day to condemn his racist statements.

By a final vote of 240 to 187, Congress voted for a resolution saying, "Trump’s racist comments have legitimized fear and hatred of new Americans and people of color.”

The resolution said Congress “strongly condemns President Donald Trump’s racist comments that have legitimized and increased fear and hatred of new Americans and people of color by saying that our fellow Americans who are immigrants, and those who may look to the President like immigrants, should “go back” to other countries, by referring to immigrants and asylum seekers as “invaders,” and by saying that Members of Congress who are immigrants (or those of our colleagues who are wrongly assumed to be immigrants) do not belong in Congress or in the United States of America.”

The tortured madness of Donald Trump: It’s clear the president is out of his mind

Published

on

Where’s Shakespeare when we need him? Only the Bard of Avon could do literary justice to the tortured madness of Donald Trump, who fluctuates between petulant self-pity and weird self-praise.

His brags are especially weird because they usually involve achievements he hasn’t made. It’s as though his saying something makes it true — even though everyone except his most naive devotees can clearly see that he’s either hallucinating or lying. In June, for example, at a rally launching his reelection campaign, he retrumpeted an old campaign promise to “drain the swamp,” assuring the adoring crowd that “that’s exactly what we’re doing right now.”
