which animal is most closely related to a hawk: shark, bat or alligator?

Question

I think that the bat is most closly related, but just was wanted some clarity of this. Can you help. A source of where you got your infomoation would be good so I could see it for myself. Thank you

Answer 1

If you you look at birds morphology it would appear superficially that it would be the bat. However the Skeleton of a bird is much more similar to that of an alligator than that of a bat. Using Cytochrome C DNA analysis the Bird is also shown to have more shared characteristics with alligators than they do with bats (or sharks for that matter).
Cladistically crocodilians and birds for a monophyletic group (no lizards, snakes, sharks or mammals in there).

Answer 2

A big difference between reptiles and birds is the presence of teeth. Dinosaurs have grown teeth perhaps to eat flesh and bugs, while early birds could well have had on their menu the first vegetal species in natural history. The hawk has to be a second-generation subject among birds, because he eats flesh in spite of being toothless.

We may confirm that with archeology, for the most ancient hawk remains are not really that ancient unless you prove me wrong. Thus the hawk could come from a bird/predator mix, and we can find hints about which predator it is by looking at the hawk's menu. The hawk should eat same species as its ground ancestor.

Problem is: that trick works too for the shark versus the typical piscie and for the alligator versus typical reptile. Sharks and alligators stand as evolved monsters in their respective categories. The bat is another story: it's one of the most generic species. They may be close to birds biologically, but they are no super predators.

Out of the shark and the alligator, i suggest that the alligator is closer to the hawk, just because he does not live (as much) in water as the shark. Biologically reptiles and fishes smell like results of a snake/bird cross. One cross was made on land, and one in the sea.

Answer 3

A hawk is a bird and birds evolved from dinosaurs which are reptiles.
A shark is a fish and they predate reptiles.
A bat is a mammal and they also evolved from reptiles.
An alligator is a reptile.
So a hawk is probably more closely related to an alligator.

Answer 4

hawks fly as do bats but thats not the right one because bats are warm blooded and birth live young, hawks are cold blooded and lay eggs.

now its narrowed down to the shark and the alligator which are both cold blooded and lay eggs, but like the hawk, only one breaths air, the other breaths through water.

also it is a theory that dinosaurs evolved into birds and that alligators are related to the dinosaurs aswell.

Answer 5

Alligator - like a hawk, it lays eggs, and as a reptile, it's closest to dinosaurs, as is a hawk.

So yeah, I see Brian had it already - and said it better too.

Answer 6

not being funny but its more than likely to be the bat as a shark and an alligator cant fly

Answer 7

in case you're speaking morphology that's the form or shape or something...it can be a bat...they have comparable physique types..physique and wings are similarily shaped. as far as genetically...they're probably greater heavily touching directly to alligators.

Answer 8

Bats are mammals.

Sharks are fish.

Alligators are reptiles.

According to modern and generally-accepted scientific theories, birds evolved from dinosaurs. So did reptiles.

Knowing that, now what is your guess?

Answer 9

I was going to respond pretty much the same way Brian L did...
He should get the 10 points.

Answer 10

alligator .the other is a fish and a mammal. reptiles are related to birds.i have killed gators. but would never kill a hawk
