Default Climate Change Likely Caused Polar Bear to Evolve Quickly

Climate Change Likely Caused Polar Bear to Evolve Quickly
The sequencing of the oldest mammalian genome from an ancient polar bear jawbone provides clues about these animals' fraught relationship with climate change
March 1, 2010
By Katherine Harmon

Climate Change Likely Caused Polar Bear to Evolve Quickly: Scientific American
excerpt from above:
Quote:
Researchers announced today that they have sequenced the mitochondrial genome of an ancient polar bear. The genetic traces they found in the bear's 110,000- to 130,000-year-old jawbone reveal that the species likely split from brown bears (U. arctos) just 150,000 years ago, at a time when specializing in arctic living quickly became an advantage rather than a liability.

The species' rapid evolution sheds new light on one of the emblematic species of climate change. Although the breed has become a popular flagship species for the issue, scientists knew little about how past climate affected the bear's evolutionary success.

The new genetic portrait gives a firmer frame to the polar bear's relatively rapid adaptations in the past. "From a conservation perspective it does tell us the polar bear has been through warming periods before...

So if they evolved to take advantage of Arctic conditions ... will it be considered that they regressed (de-evolve?) to survive non-arctic conditions?

No, it just means the powers that be can excuse global warming..'cuz after all, the polar bears will adapt. In about 150,000 years.

So if polar bears can survive oil spills from shippers, nuclear waste from Russians, heavy metals and PCBs while being run from their breeding grounds by noise pollution from oil drilling all the while being commercially hunted ... will it be considered that they evolved to glow in the dark to be all the better for hunters to see them 150,000 years from now?

1) Ulterior Motives
ESA Listing Not Needed for Polar Bears - by H. Sterling Burnett - Environment & Climate News
2) Warming World Increased Polar Bear Numbers
WARMING WORLD HAS INCREASED POLAR BEAR NUMBERS
3) Global warming nursery rhymes targeting children are retracted for exaggeration
Government rebuked over global warming nursery rhyme adverts - Telegraph

Polar Bears can swim. I am offended by the ads depicting them stretching to step from a little piece of ice to a littler piece of ice. Polar bears made it through the Medieval warming period did they not? They can make it through another warming period no? If we spend all our money on global warming will there be any left to help us make it through the destruction and poisoning of the world?

Trade beats conservation at U.N. wildlife talks | Reuters
excerpt from above:
Quote:
Short-term economic concerns hampered efforts to restrict trade in several lucrative marine species at the 175-nation Convention on International trade in Endangered Species (CITES), which wrapped up a two-week meeting in Doha, Qatar, on Thursday.

"As soon as big money gets involved, the 's' of science is crossed out by two vertical stripes," CITES Secretary General Willem Wijnstekers told reporters, meaning it becomes "$cience" spelt with a dollar sign.

"There is an enormous economic interest in catching and trading these species, and a CITES piece of paper is really a nuisance (for traders)."

AS OLD hands tell it, protecting a threatened species used to be a relatively straightforward affair at the Convention on Trade in Endangered Species of Wild Fauna and Flora (CITES). Government officials would turn up at the triennial meetings and, after listening to advice from scientists, conservationists and their own environment ministries, were likely to agree to a “listing”.

This year at its meeting in Doha, everything changed...

Governments are increasingly sending delegates from trade and fisheries ministries, rather than environment and wildlife officials...
