Farina's criticism of how Meyer interprets GOBE as the appearance of new forms that cannot be accounted for by evolution (recall the Bechly rebuttal to Farina will be posted after I finish summarizing the video):
https://youtu.be/Akv0TZI985U?t=2314
Farina starts with defining the Great Ordovician Biodiversification Event, or GOBE, as an evolutionary event happening after the Cambrian where the more generalized fauna of that era end up developing into more specialized marine fauna that would remain common through the Paleozoic era.
The GOBE occurred in two phases, the early Ordovician with some diversification and the middle Ordovician that saw a sharper rise in diversification. Farina then mentions certain species that arrived during this period such as stromatoporoid sponges, encinoderms, ostracods, corals, trilobites, bryozoans, nautiloids, and brachiopods.
Farina notes that the actual events of the GOBE doesn't fit what he believes to be Meyer's "phyla level intelligent design". The radiation (in a biological sense) of this time period is gradual and extends from the Cambrian. He then defines two terms:
Disparity - Differences between Clades
Diversity - Differences within Clades
So the Cambrian is an Explosion of Disparity, while the GOBE is an Explosion of Diversity. Farina then says in Meyer's terms this would be new body plans in the Cambrian, versus variation in the body plans in the GOBE. Farina then claims no known new phyla appeared in the GOBE. He then shows the evolution of trilobites, which says can be seen from the fossil record to occur without any Intelligent Design at all.
He then notes the biological/evolutionary radiation of the Crown Group in the Cambrian lasts until that era's conclusion, and then continues on in the post-Cambrian where the GOBE occurred. He notes this shift is so "seamless" some even include the late Cambrian as part of the GOBE.
Farina then cites a paper - this one I think, which is sadly pay walled - that notes the GOBE lasted approximately 30 million years, followed by an extinction event at the end of the Ordovician, followed by new diversification of biological forms during the Silurian. He mentions this because he feels the record shows continuous natural processes rather than the sudden conscious intervention for the production of new animal forms.
Farina then wonders what Meyer means when he says the first insects appeared without predecessors, because arthropods evolved in the Cambrian and the insects within that phylum. The last common ancestor of hexopada - insects their closest relative species spring tails - lived in the early Ordovician, while the last common ancestor of all insects lived in either the later Silurian or early Devonian. The earliest insect fossil is a pair of mandibles from Scotland, dated back to 412 million years ago (the Paleozoic Era). The earliest winged insect fossil dates to the Carboniferous which is about 324 million years ago.
(Note that he mentions these timelines are constructed with the help of "molecular clocks")
Farina also notes that as insects are within the Crustacea sub-phylum, in only makes sense that we see fossils of early crustaceans such as ostracods before we see insects. Farina then notes the major differing characteristic between insects and their fellow arthropods is their wings. So insects are a diversification of arthropod body plans, using Meyer's terminology, which would further suggest there's no need for any Design intervention. (At least according to Farina)
Farina realizes ID advocates will then ask about the evolution of the wings, but he notes this is actually understood very well rather than being a mystery which requires Design. Citing this paper, Farina notes that research into the genetic development of wing formation suggests certain vestigial genes were exapted for a new process - that of flight - across years on the evolutionary scale. Additionally wing formation involved merger of tissues from the limbs and abdomen.
He notes a similar story with dinosaurs, which as amniotes evolved from reptiliomorphs. Amniota, over evolutionary history split into two major groups - Synapsida (from which mammals evolved) and Sauropsida (from which we got dinosaurs). Additionally Sauropsida would end up giving us bird and reptile species. Farina notes these transitions are documented in the fossil record as being slow & gradual.
Farina then notes that the fossil record for turtles shows varied intermediary forms evolving gradually across time, with the same being true for birds which go back to the fossils of feathered dinosaurs. He also mentions that scales and feathers are made of the same protein, and that single point mutation can cause chickens to grow feathers where you'd expect scales.
Farina notes the fossil record also contains the gradual evolutionary story of marine reptiles. He does accept there has been some mystery about exactly when the first flowering plants appeared, but that recent research is zeroing in on the timeline. He also notes that flowers appeared due to known evolutionary transformations of existing leaf structure, thus not - in his opinion - requiring a Designer at all.
He notes there's even more about plant evolution and biology in his botany series.
Thus, according to Farina, there are documented transitional species in the fossil record for flowering plants, insects, birds, reptiles, amphibians, and more. As such, if he's correct, it would seem there's no Design needed to explain any of the examples Meyer gave as supposed novel forms.
As a special point he notes Meyer is wrong about when the first mammals appeared, by about 100 million years.
Next post will get to what Farina believes Meyer gets wrong about genetics. Thankfully I believe this is the last topic of the video, and once I finish summarizing it I'll get into Bechly's rebuttals...and then Farina's rebuttal of Bechly...
