Evolution Hour 178 Jeanson plays the vestigial means functionless trope that Jackson and I discussed in Rocks. He waves Dines 2014 https://onlinelibrary.wiley.com/doi/full/10.1111/evo.12516#:~:text=Second%2C%20pelvic%20bone%20shape%20%28independent%20of%20size%29%20has,cetacean%20pelvic%20bones%20are%20targets%20of%20sexual%20selection on cetacean pelvic bone selection for copulation, as if it invalidated the vestigial (or pelvic) nature of those bones.

And then Jeanson waved a pile of creationist sources on vestigial matters: Gurney 1999 https://answersingenesis.org/human-body/eyes/is-our-inverted-retina-really-bad-design/
Bergman 2008 https://creation.com/is-the-human-pharynx-poorly-designed
Bergman 2011 on laryngeal nerve https://creation.com/recurrent-laryngeal-nerve-design (which we cited in Rocks)

Part 2: back in December AiG tweet lobbed a 2018 post by creationist Sanders https://answersingenesis.org/aquatic-animals/fish/rapidly-reproducing-killifish-defy-evolution/ claiming “Killifish deserve a deeper look as their design strongly point to a designer.”

Sanders disingenuously noted how “killifish have only rarely been addressed in major creationist literature and generally only in response to evolutionists claiming they had evolved,” which consisted of just Brian Thomas in Acts & Facts 2017 https://www.icr.org/article/fast-changing-killifish-swim-past-evolution

Along the way Sanders cited Podrabsky 2001 https://journals.physiology.org/doi/full/10.1152/ajpregu.2001.280.1.R123 & Hrbek 1999 https://onlinelibrary.wiley.com/doi/pdf/10.1111/j.1558-5646.1999.tb04533.x early work on them

Cellerino 2016 https://onlinelibrary.wiley.com/doi/full/10.1111/brv.12183 & Hu 2018 https://web.stanford.edu/group/brunet/Hu%20and%20Brunet%202018.pdf on their role as a model organism

Furness 2016 https://www.researchgate.net/publication/276268352_The_evolution_of_an_annual_life_cycle_in_killifish_Adaptation_to_ephemeral_aquatic_environments_through_embryonic_diapause and the equally extensive 2015 paper https://royalsocietypublishing.org/doi/10.1098/rspb.2014.2189 which went into the details on the evolution of the diapause egg that can survive out of water a bit longer, and the repeated appearance of the feature in those fishes where a selective pressure favored it.

And Vrtilek 2018 https://www.cell.com/current-biology/fulltext/S0960-9822(18)30822-4 on the fastest maturing fish

And Valenzano 2018 https://www.cell.com/cell/fulltext/S0092-8674(15)01488-9 which tracked the varying longevity of the genus to particular genes, which Sanders didn’t allude to specifically, but did authority quote from the abstract, “Remarkably, these genes are clustered on the sex chromosome, suggesting that short lifespan might have co-evolved with sex determination.” To which conclusion Sanders jumps, “The researchers are essentially claiming that the abbreviated life cycle of the killifish came into existence with its reproductive capabilities.” That’s not quite the same thing.

But curiously not citing Thompson 2016 exploring the candidate genes involved in diapause in vertebrates generally and killifish in particular https://academic.oup.com/mbe/article/33/9/2391/2579307

And for fun, Lovas-Kiss 2020 on how fish eggs can be dispersed by birds eating and spreading them, https://www.pnas.org/content/117/27/15397

Thanks to all your help, I’m doing my part on the science defense front, having written THE coverage of how antievolutionists ignore the reptile-mammal transition macroevolution evidence https://www.amazon.com/dp/1540736296/ref=sr_1_2?ie=UTF8&qid=1481509663&sr=8-2&keywords=Evolution+slam+dunk which paleontologist Christine Janis described in her Amazon review as “an incredible tour de force”

And now the new https://www.amazon.com/Rocks-Were-There-Creationist-Questions/dp/B0858TGBQX with Jackson Wheat puts the Source Methods scalpel to use carving YEC to pieces. We’ll have Volume 2 out in due course.

Jackson & my short promo for Rocks 1 https://www.youtube.com/watch?v=2K7FneJBbUg&feature=youtu.be

Source Methods works as a debate approach too. For example, catch my 2018 debate with Kent Hovind https://www.youtube.com/watch?v=g1JRnnOl27Y
