The Most Recent Evidence of Evolution

Killer idea.

Lets use this thread to post links to some of the most recent examples of new (or newer) evidence for evolution. That way, we can have a one stop source for anyone looking for any.

Here's mine for today:

Genetic Research Reinforces Theory of Evolution



“Discussion over evolution and Intelligent Design really has centered on whether pseudogenes, sometimes called ‘junk DNA,’ have a function or not. The suggestion is that an Intelligent Designer would not make junk DNA, so if a pseudogene does have a function, this is claimed to support the idea of an Intelligent Designer,” Dr. Nicholls said. “But there is no evidence that any of the 20,000 pseudogenes are functional. Our research proves this Makorin pseudogene does not have a function. It has continued to mutate over its short life of a few million years, a fact that supports evolution, and eventually will be discarded from the mouse genome.”

100 million year old bee discovered in amber

This one's from last year:

A refined physical map of chromosome 17q21.31 uncovered a 900-kb inversion polymorphism. Chromosomes with the inverted segment in different orientations represent two distinct lineages, H1 and H2, that have diverged for as much as 3 million years and show no evidence of having recombined. The H2 lineage is rare in Africans, almost absent in East Asians but found at a frequency of 20% in Europeans, in whom the haplotype structure is indicative of a history of positive selection. Here we show that the H2 lineage is undergoing positive selection in the Icelandic population, such that carrier females have more children and have higher recombination rates than noncarriers.

This one is more recent:

In vertebrates, paralogous Hox genes play diverse biological roles. We examined the interchangeability of Hoxa1 and Hoxb1 in mouse development by swapping their protein-coding regions. Remarkably, the mice expressing the Hox-B1 protein from the Hoxa1 locus, and vice versa, are essentially normal. We noted, nonetheless, a specific facial nerve hypomorphism in hemizygous Hoxb1A1/2 mice and decreased viability in homozygous Hoxa1B1/B1 embryos. Further, we established a mouse line in which we have inserted the 107 bp Hoxb1 autoregulatory enhancer into the Hoxa1 promoter.
Strikingly, the newly generated autoregulatory Hoxa1 gene can deliver the functionality of both paralogs in these mice, providing normal viability as well as proper facial nerve formation even in the Hoxb1 mutant background. This study affirms that subfunctionalization of the transcriptional regulatory elements has a principal role in the diversification of paralogous Hox genes. Moreover, we show that the ancestral
vertebrate Hox1 gene can still be experimentally reconstructed.

The sad thing is not matter how much evidence we present christians will never believe!

And the Evolutionary Beat Goes On

(From TenSpace's link:

Europeans, for example, show strong changes over the past 10,000 years in genes that affect skin color -- as humans moved into northern Europe, where there was less ultraviolet light, there was a strong evolutionary advantage to having lighter skin to allow in more ultraviolet light, which is needed to synthesize Vitamin D.

Finally a real explanation for skin color

pppft, we all know some people are brown because when heaven was split between the followers of jesus (whities) and satan (devils), those who couldn't decide were punished for not choosing jesus by being born black-to-coffee coloured on earth. gees, you atheists are dumb.
(is this an actual mormon belief or did the catholic church fuck up even their anti-mormon school propaganda?)
