Sweeping gene survey reveals new facets of evolution

So it seems there would be a lack of selection pressure for intermediate forms.

On the contrary. They were selected out.

Too late for Hawking. He now knows the truth.

Swear to empedocles...khaldoon(sp?)...wallace..hutton...lyell..lysenko...lamarck....erasmus or charles darwin? You mean most of present species and families are of recent origin? I want my slow imperceptible evolutionary model back!

LOL-

[Mom MD]

Yup. Actually another nail in the coffin of evolution

[VanShuyten]

One of the commenters had this to say (part 2 of 2):

“Second part : The FLAW in this study is caused by :
A- Mutation rate is different in each and every bp (base pair) of the COI gene and this mutation rate is SAME in every animal species in other words number 325 bp (base pairs mutation rate ) in a given generation time period has only 4 choices ( A\T\C\G ) and this changes –REPEATEDLY - .
B- Conserved mutations preserved for ` optimum function of COI gene certain base pairs –has to be the same- and fixed- ( meaning no coding variability allowed because that variability is NOT COMPATIBLE WITH FUNCTION OF THAT GENE and life –meaning lethal- C- COI gene has total, 255 variable sites and 403 conserved sites .
So we have only 255 variable sites changing in between ( A\T\C\G ) REPEATEDLY IN ANY SPECIES OVER MILLIONS OF YEARS like a `Cycle of a clock` so you can `NOT` determine the beginning or end of any species as a life form – period .”

[[I mean that if an organelle lacks, say, one component out of 1,000, it doesn’t merely work 1/1,000th less efficiently: it doesn’t work at all.]]

He should have worded that a little more carefully because evolutionists make the silly argument that it could lose a NON ESSENTIAL component and still function- Behe of course did NOT mean that losing a non essential part would result in failure- He meant that losing one IRREDUCIBLY COMPLEX and necessary part would result in something being non functional. The evolutionist’s counter claims were very disingenuous because they knew exactly what he meant but misrepresented his statement

a handheld genetic test used to unmask sushi bars pawning off tilapia for tuna could deliver deep insights into evolution, including how new species... The study's most startling result, perhaps, is that nine out of 10 species on Earth today, including humans, came into being 100,000 to 200,000 years ago.

If you knew sushi, like we know sushi.

Thanks CondorFlight.

Dead link now, but the archive has probably been moved.

Evolution in Your Face
by Patrick Huyghe

Lake Victoria, Africa's largest lake, is home to more than 300 species of cichlids. These fish, which are popular in aquariums, are deep-bodied and have one nostril, rather than the usual two, on each side of the head. Seismic profiles and cores of the lake taken by a team headed by Thomas C. Johnson of the University of Minnesota, reveal that the lake dried up completely about 12,400 years ago. This means that the rate of speciation of cichlid fishes has been extremely rapid: something on average of one new species every 40 years!

[BigEdLB]

That will be tough since he died last month.

[Fedora]

And yet—another unexpected finding from the study—species have very clear genetic boundaries, and there's nothing much in between.

"If individuals are stars, then species are galaxies," said Thaler. "They are compact clusters in the vastness of empty sequence space."

The absence of "in-between" species is something that also perplexed Darwin, he said.

[Crucial]

Oh yeah. I completely forgot.

[Paul R.]

“Scholars have previously argued that 99% of all animal species that ever lived are now extinct. Our work suggests that most species of animals alive today are like humans, descendants of ancestors who emerged from small populations possibly with near-extinction events within the last few hundred thousand years.”

The idea that most species alive today evolved relatively recently should not be surprising at all. Just look at the climate pattern: Most everything (life) has been repeatedly pruned back by repeated bouts of truly harsh climate (extensive periods of glaciation and drought).

[Mr Radical]

"This means that the rate of speciation of cichlid fishes has been extremely rapid: something on average of one new species every 40 years!"
Surely his math is wrong? You cannot simply divide 300 species into 12,400 years. If one believes in random mutation then two species have twice the probability of speciation of one; three have three times the rate, four have four times the rate, etc. A bit like the grains of wheat on the chessboard, you could go from one to 300 in just eight or nine moves. That is 12,000 divided by 8 or 9 ≈ 1400-1500 years on average per (individual) speciation.
The timing of the very first random speciation could make a big difference to the outcome after 12,400 years.
IF one believes in random mutation, of course...

[wbarmy]

There is also the need to standardize an exact definition of “species”. Do these Cichlid fish breed amongst each other? Can they interbreed? Is there an actual major genetic difference among the cichlids or are they actually sub-species.

It was even shown that although Darwin’s Finches did not like interbreeding with the other finch “species”, they were able to when reproductively isolated and produced variants mid way between the parent finches.

This is a very loose definition of species and can be used to prove almost anything in evolutionary terms.

“Has anyone ever seen evolution?” Shut up. No questions allowed.

I DO so wish they would make up their minds!!

Not yet; I'd think.

Ecclesiastes 9:5

For the living know that they will die, but the dead know nothing; they have no further reward, and even their name is forgotten.

 

 

Daniel 12:2
Multitudes who sleep in the dust of the earth will awake: some to everlasting life, others to shame and everlasting contempt.
 

1 Corinthians 15:51-52
Listen, I tell you a mystery:

We will not all sleep, but we will all be changed—in a flash, in the twinkling of an eye, at the last trumpet.

For the trumpet will sound, the dead will be raised imperishable, and we will be changed.

 

Ephesians 5:14
This is why it is said: “Wake up, sleeper, rise from the dead, and Christ will shine on you.”

 

[Elsie]

If Evolution EVER worked; then it is STILL working today.

So just WHERE are all of these ‘mutated changes’ that should be all about us?

We’ve been told that most of these changes do NOT advance a specie; so where are today’s bad ones?
