'Did Life Evolve Faster Before or After the Extinction of the Dinosaurs?'
In the immediate aftermath of the K-T/K-P extinction, was not evolution slower because there was less life on the planet?
Note that the topic AiG are referring to is eutherian mammals ONLY - since they are flagging THIS page (thus the title of Lacey's article is SIMPLISTIC and MISLEADING):https://www.sciencedaily.com/releases/2 ... 221710.htm
'Our ancestors evolved faster after dinosaur extinction.'
This conclusion reached in this paper reported at ScienceDaily - looking at 10 MILLION years post K-T - is not inconsistent with my reaction above (if that was correct).
And a similar conclusion was reached here:http://rspb.royalsocietypublishing.org/ ... 3/20153026
I think the YEC 'worldview' alternative timeline (just 4,500 years since a 'worldwide flood' to fill the planet with life) would prefer to claim that rapid speciation/rapid post-flood evolution slowed down after the dinosaurs somehow (in their timeline) ALL went extinct. After all they claim there was - a few thousand years back - much faster speciation than is ever observed in real time today. Also the last dinosaur species must have died very 'recently' ie in historical times according to YEC 'timelines' since those dinosaurs (hundreds of species) had first to (re-)colonise the planet post-flood. (And the YEC timeline is wrongly considering what happened to those eutherian mammals, after the K-T ie 'post-flood' by their reckoning, with the dinosaurs 'NOT yet extinct'.)
But what conclusion(s) do they actually reach? (Comments below are chronological through the article.)
"A larger starting population [after a 'worldwide flood'?!] and shorter generational times may have helped these animals form more species more rapidly immediately after the Flood." Less predation/competition for food would eventually help with speciation and evolutionary change (but first AiG have to 'remove' those dinosaurs from their imagined scenario).
"But as successful as these mammals were immediately after the Flood, a large percentage of them disappear from the fossil record fairly quickly, meaning that they went extinct not long after the Flood." Something YECs cannot explain (despite references to a 'recent' ice age or implied claims that dinosaurs were still around for many centuries, and so forth). And it's also totally UNBIBLICAL. Sub-heading 'How Can This Be Explained in a Biblical Worldview?' Very inadequately if this article is anything to go by.
"Science Daily posted a news item on another recent study by researchers at the University of North Carolina, which stated that evolution occurred up to 4,000 times faster on early earth microorganisms from around 4 to 3 billion years ago."
And this paper explains why - much hotter temperatures than now, causing more mutations than now:http://www.pnas.org/content/113/29/8194
And MORE running around the houses. Because Lacey and AiG have an agenda of trying to rubbish evolution (even if the planet is very old which they will not accept). "We have stated many times before that mutations are not (as evolutionists claim) the driving force of molecules-to-man evolution. So finding that intense heat increases the rate of C-T mutations does nothing to speed up the pace of evolution." What arrogance. And circular reasoning. "The problem for evolutionists is that the only beneficial mutations ever observed do not add new information to the genome that can cause one kind of animal to evolve into a completely different kind of animal; they merely reshuffle or sometimes delete genetic information." As expressed in that sentence, the alleged 'problem' is fictitious. YECs totally deny gene duplication for instance.
And here is the punchline:
"So to answer the questions posed by these two new studies—did evolution happen at a faster pace from 4 to 3 billion years ago, and again after the extinction of the dinosaurs 66 million years ago—the answer is no. God created the earth and the universe a little more than 6,000 years ago, and by Day 6 He had made bacteria, dinosaurs, and mankind (and every animal, plant, and fungi). He placed massive variety in the genome of every creature, and He made them perfect and fully formed and functional."
Thus, because of their totally fictitious timeline, YECs are forced once again to REJECT a scientific conclusion published in a peer-reviewed science paper. They give NO valid reason (that addresses K-T 65 million years ago and then 10 million years after that, instead of muddying the waters with '4-3 billion years ago', and addresses eutherian mammals only). (Lacey suggests the K-T boundary was the time of 'Noah's Flood'; but there are NO dinosaur fossils ABOVE the K-T boundary.)
Of course this conclusion (referring to POST-flood in general and when they falsely claim dinosaurs were 'not yet extinct') completely RUBBISHES claims in all those recent AiG Nathaniel Jeanson articles. Such as this one:https://answersingenesis.org/natural-se ... diversity/
From the abstract: "We also show that created heterozygosity, together with the operation of natural processes that are observable today, is sufficient to account for species’ phenotypic and genotypic diversity." All this had to commence straight after a 'worldwide flood' 4,500 years ago, in order to manage to rapidly re-fill the Earth with all the extant life, and fossils, found across the planet in recent centuries; yet Lacey is now claiming that speciation (he calls it 'evolution' and claims this process is fiction) was 'not' more rapid after the dinosaurs went extinct - which of course is at the 'flood' K-T boundary and NOT later.
In fact Lacey admits as much (but without referring to all those Jeanson articles published after 11 June 2016):
"Creationists also do not disagree with linear, (and in some species-rich kinds, rapid) post-Flood speciation; in fact Creationist models of animal dispersal, geographic isolation, and adaptation predict that from the time these genetically-diverse animals departed the Ark, they would have speciated and adapted rapidly into new environments." Note the phrase "from the time ... departed the ark" (they allege this is 'post K-T' since the K-T is 'during' the flood). So - if the 10 million years after the K-T are immediately 'post-flood' - how come evolution/speciation of eutherian mammals was 'not' faster then than pre K-T? It makes no scientific sense. (Neither does Jeanson's conflicting claim.)
There are no real answers here. Just lots of denials and special pleading.
From the conclusion:
"We are labeled as being naïve and accused of accepting “rapid evolution” by postulating the many new species that formed in the first few hundred years of the post-Flood period. But this rapid migration and subsequent geographic isolation, which can give rise to rapid speciation, explains how land-bound life has expanded to its current high level of diversity, even after the genetic bottleneck caused by the Flood." He also whinges about articles like this one:https://thenaturalhistorian.com/2015/12 ... ahs-flood/
In other words, AiG are rejecting science (science many Christians accept) and creating their own facts. They are not facts. And Lacey's article - unlike those of Jeanson during 2016 - is unscientifically ruling out (more rapid than hitherto) post-'flood' and 'post K-T' evolution/speciation. He even uses the word 'life' in his title. Yet Lacey still says, correctly, that AiG postulate "the many new species that formed in the first few hundred years of the post-Flood period". Except for eutherian mammals (and DESPITE some real evidence for such) apparently?
I call that having your cake and eating it.
It would not be necessary if YEC was real science, I suggest.
