Dinosaur Evolution: A Journey from Tetrapod to Bird

Hey everybody, I'm returning to finish this project!

Okay now I'm returning

I like birds

They're cool and pretty

Owls are SOME of my favorites, along with titmice, emus, parrots, etc.

I love birds too, especially the Eagles

Dilophosaurids were originally considered Coelophysoidea for a long time before fossil evidence showed they were actually more advanced and closer to Tetanurae theropods rather than Coelophysis. The Dilophosaurids' closely related members were Liliensternus liliensterni and Zupaysaurus rougieri and may have been sister clades to Dilophosauridae.

Now Dilophosauridae pretty much had only two members in it:

Dilophosaurus wetherilli

Dracovenator regenti

Former members like Cryolophosaurus ellioti and Sinosaurus triassicus have since been reclassified as basal Tetanurae

How do you know evolution is true? Give me some evidence

GmkGoji,

Do you think that somebody created earth?I don't,the evidence is that some tiny cells have evolved and became bigger,and for Dinosaurs...yes they did evolve,and simply,if Rodan existed,will he only be a bird?Wont he evolve and become stronger?There isn't evidence that someone created the planet!But its your opinion,if you don't think that evolution is true,well thats your opinion.

Well... I do believe someone created the Earth.

Also, how do you know that the cells "evolved" into bigger organisms?

Also, I do believe in micro-evolution. That animals adapt to their environment. BUT, I don't believe that a fish could turn into a bird.

Well, admitting micro evolution is true means that macro evolution is true, because it’s just multiple cells doing it at once. And because of how cells are formed and DNA, that’s easily possible. Besides, you have to believe in mutations. Evolution, essentially, is just a mutation forming, and if it is beneficial the creature with that trait will be more likely to survive and reproduce, and so that trait is more common over time across the population. Then more mutations over time happen, until the point it can no longer breed with the initial species it stemmed from and is a new species. Also, if someone created every species at once, then why are so many so similar, and they all have a similar body plan and structure (basically)? Shouldn’t they all be each more different than the last?

So... a amphibian can mutate to have wings?

Not BIG mutations like that. I meant a mutation in one specific part of the DNA. To evolve wings, that would take a great number of mutations over time to create functional wings. However, it's theoretically possible. I mean, if it was somehow an advantage, then over the course of millions of years some species of amphibians could evolve to have wings, yes.

Also, before you say something like: "We've never SEEN evolution happen!" I'd like to refer you to this:

Also these for good measure:

Well said, TheLazyFish

Saying that Micro-evolution means Macro-evolution is true is not a viable explanation that Macro-evolution is true.

Also, saying that a species develops over time through mutations is seriously wack. 

Take for example, the Bombadeer beetle. It shoots flammable substances comprisied of special chemicals to deter predators. How on Earth would many, small, random mutations be able to make a Bombadeer beetle have a incredible survival mechanism like this?

The beetle has four chemicals. Two, which mix together and EXPLODE. But, the beetle does NOT want that to happen inside his own body. So, the beetle has ANOTHER chemical which dilutes both chemicals. The fourth neutralizes the third chemical, which allows for 200 degree liquid chemical spray!

How does a bunch of small, random mutations cause such a complex and amazing animal? Especially on the scale of an insect? I'm fine with debating more, just tell me what you guys think. It's a 2v1! Or a 1v3? I dunno. 

Nobody created and evolution does not exist!

DOES THAT MAKE SENSE!!?!??!

Gmkgoji its called Natural Selection, Speciation, and Genetic Drift. As for the Bombadeer Beetle, simply for generations a basal beetle feed on plants or materials holding those chemical compounds then through evolution gradually developed that survival mechanism to its modern form.

Curious you used the bombadeer beetle and not dispute my evolution chart of how Fish became amphibians to basal reptiles to dinosaurs to birds

Does a fish grow legs and walk on land? 

Eh, I don't think so

Welp,from that information,do you believe in god?I don't,because there is no proof that he exists.But there is proof that evolution exists,looks like no one created earth...

Typical Creationist comeback, no a fish doesn't simply grow legs.

The fish that all backbone land animals evolved from were the lobed fin fishes, their only surviving members are the Lungfish and the Coelacanths. The linage of Lobefin fishes we came from were called Tetrapodomoprhs, they advent of lung devalopment started when oxygen levels in the water were depleting and the oxygen in the air became breathable for vertebrates. So through natural selection the swim bladder slowly developed into lungs.

So now the early tetrapodomorphs would slowly crawl up on land with their fleshy fins, Lobefin fishes have finger bones in their fins unlike Rayfin fishes. The lobefins slowly started developing into more finger-like structures as millions of years and a shit ton of generations of lobefin fishes having sex and producing offspring to carry these mutations. 

... I feel like everyone ignored the videos I posted... I'd be fine with that if the first one wasn't so important...

YAAAAAAAAWWWWWWWWWWWWWn...

Can we all agree to disagree? 

Or maybe argue about what killed most of the dinosaurs?

Which video

Ah yes,

ENSLAVED VIDEOS WHICH TELL US EVOLUTION!

Honestly the first link was most important... because it talks about instances where we've seen evolution happen over the course of a few decades, a process called rapid evolution. It brings up 3 fascinating instances of this.

 Gmkgoji this is a topic about Dinosaur EVOLUTION so evolution is the main topic here. There is too much evidence to support Evolution (Genetics, Domestication, Medical science, basic understandings of Biology, and most importantly the Fossil Records) to be simply dismissed as a agree to disagree.

Our understanding of evolution grows more and more with each new fossil discovered

The fossil record does NOT show evolution

Hell just look at your individual human, you may have people with enlarge hearts or enlarge kidneys and the medical problems that go with them. if humans were created equally by a creator how come Humans and by extension all life come in all shapes and sizes, hmmmm?

At a creationist stand it doesn't really make and sense outside oh God made you that way just because. So God dilbertly made you born a cripple or dilbertly made you prone to heart attacks, I thought we were all created equally?

At an Evolution stand point, which you can still believe in God by the way, just not creationism. The reason why everyone is different and not equal is because these difference are supposed to allow us to thrive in different environments as well as weed out the less suitable ones. This applies to survival situations if we didn't have civilizations, the advent of Civilization removed humans from most of these natural pressures.

GMK the fossil records does if you know to read clades

IT SHOWS THAT EVOLUTION EXISTS!

I DON'T CARE WHAT PEOPLE SAY!

EVOLUTION IS TRUE!

NOBODY CREATED EARTH!

Well how do you know the clades are true? You said it yourself, it is BELIEVED to be true.
