Colourful birds quicker to evolve, says study

Published

on

Birds with multiple versions of their colour patterns evolved into new species more quickly than those with uniform plumage, Australian researchers revealed in a significant genetic study published Thursday.

The University of Melbourne research, published in “Nature”, found that birds with more than one version of its markings such as the Gouldian finch, which can have a red, black or yellow head, “rapidly” evolved into new species.

The study proves a theory in evolutionary biology first proposed 60 years ago and helps shed light on the processes that create biodiversity, according to lead researcher Devi Stuart-Fox.

“We’re trying to figure out how and why new species evolve… the triggers and catalysts,” she said.

“Why will some populations evolve into new species while others just stay the same for millions and millions and millions of years?”

Though they look different, the finches in the study coexist within a single population and Stuart-Fox said the study found they evolved into genetically new species much faster than uniformly-coloured birds.

“This is the first time that we’ve been able to show that it actually speeds up speciation rates or rates of evolution,” she added.

Hawks, eagles, owls and nightjars were the focus of the Melbourne study but birds are not the only animals with so-called “colour polymorphic” species — it was also a feature of fish, lizards, butterflies and snails.

The different colour versions often varied in things like physiology and behaviour and Stuart-Fox said their inclusion within a single population “might allow (it) to exist in a broader range of environments”.

Some researchers were examining whether and how colour polymorphism contributed to species’ resilience and adaptability to external factors such as habitat loss and climate change, she added.

Trump unravels over Ukraine call in extensive thread– then blames Democrats

Published

on

President Donald Trump continued to unravel over the call he had with Ukraine on July 25.

"This Scam going on right now by the Democrats against the Republican Party, and me, was all about a perfect phone call I had with the Ukrainian President. He’s already stated, NO PRESSURE! Where is the Whistleblower, or the 2nd Whistleblower, or the “informant?” All gone because their so-called story didn’t come even close to matching up with the exact transcript of the phone call. Was it a Corrupt Adam Schiff con? Why didn’t the IG see this? When do we depose Shifty Schiff to find out why he fraudulently made up my phone call and read this fiction to Congress and the American People? I demand his deposition. He is a fraud, just like the Russia Hoax was, and the Ukraine Hoax is now. When do the Do Nothing Democrats pay a price for what they are doing to our Country, & when do the Republicans finally fight back?"

Trump is furious over news coverage of Mick Mulvaney’s flub — and he’s growing ‘increasingly frustrated and agitated’

Published

President Donald Trump is watching Mick Mulvaney going down on cable news, said one political analyst on CNN Sunday. The criticism of the chief of staff came after Trump spent the weekend watching media coverage of Mulvaney's flub, the network reported.

"Trump has voraciously consumed news coverage about Mulvaney and has become more agitated," the source said according to the report. "Specifically, the President is concerned, according to the source, that Mulvaney is not transitioning enough to the role he is in now -- helping to lead the impeachment inquiry defense from the West Wing."

Speaker Nancy Pelosi and Donald Trump

President Donald Trump tweeted his anger about Speaker Nancey Pelosi (D-CA) taking a delegation of leaders to Jordan to meet with those working on Syria.

"Pelosi is now leading a delegation of 9, including Corrupt Adam Schiff, to Jordan to check out Syria. She should find out why Obama drew The Red Line In the Sand, & then did NOTHING, losing Syria & all respect. I did something, 58 missiles. One million died under Obama’s mistake!" Trump tweeted Sunday.
