Grasses are plants of the angiosperm class, they originated in the Triassic, about 160 million years earlier than the ICR "story " would have you believe (Taylor and Taylor 1993). The issue about grasses being a "problem" to Darwinian thought, is total bullshit. The evolution of plants is a problem of paucity of fossils. Grasses , for example, are usually found in specific environments of savannah -like conditions and, such conditions becasme more pronounced in the mid Triassic as the mid circumferential currents and pangea were splitting and currents diverted and "rain shadows" more pronounced. Things dont fossilize in oxygen rich soils, they decay and are "composted"
The data is what the data is. NO data presents problems to science. Science attempts to understand its meanings(and these meanings are naturalistic)
I wonder what the ICR is trying to peddle with the grasses story? . Hell, these guys are out there still faking fossils for the vast ignoranti . Like last years rubber dinosaur fossil with a hominid in its mouth. That only took a few weeks to " toss on the rubbish pile" of old Creationist deceptions. Gungasnake was so enthralled when he published the link and then disapperaed when it was denounced by the right reverend "Bubba" breinard
The radiation of insect species in the late Jurassic and Creataceous was mostly responsible for the rapid spread of all angiosperms. (This was the way I was taught in the 1970's in grad school paleo). Today we know differently, we have data that pushed back the development of angiosperme to much earlier. Remember, in the 1960s we didnt understand continental drift very well and most earth scientists didnt accept it. Now, with aglobal tectonics view in mind, we can see WHY certain species became isolated and developed separate linneages that were related to. but not descendant from other foundation species.They drifted apart(literally) while they were dveloping separate species
real life asksQuote:The similarities in morphology between different whales ( or whatever you choose to compare) are the basis on which you have inferred relationships between them. It does not prove a relationship. Not even close. Does the presence of wings prove a relationship between bats and birds? Does bipedal locomotion prove a relationship between all the creatures which share it?
. Youre boxing yourself into a logic corner rl. Namely, since we infer that something occured by virtue of all the data and evidence. Yep, , why not use the word that we use in science. WE CONCLUDE by virtue of all the evidence and data. What have in your quiver thats equally robust?
I Think the answer to that is NOTHING
Im not going to take the time and rehash the whale story again, because I know youve heard it and just deny it, even though youve got no counter other than the myth and other nice fuzzy stories.
Im not a catastrophist , because , within the passage of deep time, "catastrophies" such as bolide hits, megavucanism and periodic global warming followed by rapid cooling, occur in almost Uniformitarian frequency. So we calculate return frequencies and include these items in the large "whole earth" startigraphic column
The fact that 95% of all life disappeared in the end of the Permian and 65% died out at the end of the Cretaceous is undisputed by radiochemistry, paleo, structural geology, mantle and deep layer geophysics,Other mass extintions occured in the Devonian, Ordovician, early Phanerazoic, Eocene and the Pleistocene/Holocene.Raup had produced a "kill curve" based upon return frequency and actual species wiped out. Fossil evidence for these events is not denied even by IDers. (They say that they agree that niche "abandonment" is a great adaptive radiation mechanism because predation decreases markedly.
Im wondering where you go from here. You can keep denying data, but yet try to occupy some as "your own" for no other reason than to try to discredit the well established and well-understood interlacing of many disciplines of science.
