is there any hard evidence that dinosaurs "evolved" into birds? Besides them sharing certain bio-mechanical structures? And besides certain intermediary lizard-feather species existing in the past that went extinct.

This theory sounds more baseless and illogical than the idea of abiogenesis.

The theory is plausible if you look at it as a change in atmosphere composition and diet resources restricted high survival rates to only the smallest of it's respective species.

>> No.9199055

>>9199030

Particularity is irrelevant. It follows by logic and observation that humans have parents, and human parents have human parents, etc. Grandparents are neccesary. Finding the particular one is a matter of empirical analysis, with some uncertainty involved, blood tests and familia history is sufficient to come to a reasonable decision.

This is nothing like the idea that birds came from dinosaurs, in general, since it doesnt follow by logic or observation. and finding out which particular breed of dino gave rise to what breed of bird is not what is asked. I don't need that much specificity.

Paleontology isnt a hard science.
it cant be held up to the same standard or trusted like real geology can be.

that being said, its still got plenty of useful information and isnt all just made up bullshit.
you cant fuckin nit pick at it as hard though because it is soooooooo circumstantial and really the excepted theories are just a "best guess"

evolution is real, but if you want evidence tracing X to Y, you are not going to get it due to how fossil preservation and preservation bias logically works.

its like getting a 1/4 of a slideshow of a movie and trying to understand it. There are plenty of unsolvable gaps in the details.

everything is an interpretation (backed up with hypothesis supported with evidence)

"Grandparents are neccesary. Finding the particular one is a matter of empirical analysis, with some uncertainty involved, blood tests and familia history is sufficient to come to a reasonable decision."
It's the exact same principle with birds and dinosaurs. Dinosaurs may or may not have descendants. Birds must have ancestors. It's just a matter of clearing up who is related to who.

>> No.9199114

>>9198666
Technically speaking, no, they didn't come from dinosaurs, they ARE dinosaurs. And paleontologists never assume current species came from fossile species, only that they must have a common ancestor. Just like pigs and humans share a common ancestor, birds and dinos too, making all of them belong to Dinosauria, "the dinosaur group"

Biologists can only propose theories as to the phylogeny of species that have been extinct for longer than any DNA trace lasts. Evidence of similar biochemical structures and mounting evidence of more bird-like traits among dinosaur fossils being uncovered and given more scrutiny seems to suggest that birds have a closer common relative to dinosaurs than any other classification. Normally one would think of reptiles as the key there, but if you take into consideration the relative age at which reptiles were around, there's been a lot of time for evolution. While evolutionary pressures aren't so high for such adept species as many reptiles are at exploiting niches, even incidental mutations that have no necessary change on fitness would build up to the point of speciation by now.

That last part is more tangential to the argument, though. At this point we run under the theory that all life evolved from one common ancestor, and so we classify under that model. It's convention- and it hasn't been disproven, so it's fairly strong until evidence arises that causes the foundation to be questioned. There are some theories that seem to imply extraterrestrial DNA, for example.

More than that, my little cracker. At one time your direct ancestors were some sort of single celled organism, like an amoeba or a bacteria. And if you continue to take a direct ancestral line then at one point they were an assortment of free floating amino acids, and other basic molecules. But why stop there? Keep going back in time and at once stage your direct ancestors were a collection of hydrogen atoms just about to under go fusion with other hydrogen atoms in the core of a star that then blew the fuck up and spread your disgusting ancestral components here, such is the pity.
