If all birds are Dinos and all Dinos are lizards and all lizards are reptiles are birds reptiles?

Question

Have fun with this one, watch out for the catch!!!

Answer 1

Whether birds are dinos is a matter of definition. From a strict cladistic point of view, yes. But I think it would be better to make up some other name for the dino clade to avoid confusion with the traditional non-cladistic group called dinos.

By the same token, although vertebrates can be grouped in two clades
- softboned fish such as sharks
- raiboned fish and their desendants, such as reptiles and mammals

nobody would say that a mamal is a rai-boned fish. Instead, we invent an alternative name for the rai-boned-fish clade.

Answer 2

New evidence points out that dinos weren't lizards,
however birds are closely related to reptiles, phylogenetically speaking, much closer than mammals for instance

Answer 3

What you are saying is like saying, all dogs are tetrapods, and all frogs are tetrapods, so are all dogs frogs? It is wrong to say all dinosaurs are lizards. Dinosaurs share a common ancestor with lizards, but they themselves are not lizards. Dinosaurs are classified as crocodilians and then further subcategorized depending on their hip bones. Birds may be dinosaurs, but dinosaurs are not lizards, they may share a common ancestor with lizards, but they are not the same, similarly, humans are not monkeys, we just share a common ancestor.

Birds and reptiles are similar in that they are both sauropsids, have holes in top of skull, but the types of holes may vary between the two groups, and many other characteristics now vary as well.

Every species can pretty much be linked to another species if you go back far enough. Humans and sharks are both gnathostomes, but we are not the same.

Answer 4

um...no. At one point, all reptiles were amphibians. Just like, at one point, all mammals were reptiles. And the amphibians at one point were fish.

So on the one hand: no, birds are not reptiles because they are fish.

On the other hand: birds are not reptiles because they evolved into a completely different genus of animal.

On yet another hand (my invisible, magical third hand): birds are not reptiles because God created everything as it is now, and so the Alsation dogs which exist now, existed at the beginning of time, and did not (as has been recorded so ridiculously) get breeded up from wolves, because that would be silly and a direct proof of evolutionism, which is patently absurd.

(please note the cynicism in the magical third hand argument)

On all three hands, the answer remains no.

Answer 5

Dinos weren't lizards

Answer 6

Logical fallacy--all Dinos were not lizards. At that point, the whole thing breaks down.

Answer 7

yes
yes
my god yes
