Precisely. But it could still assimilate with more organic tissue to become bigger. The Thing is basically an amoeba like ‘The Blob’.

I'm inclined to agree their intelligence depends on how advanced the host. Does that mean if one of them gets an arm (or anything else) cut off, the appendage is "dumber" because it's a smaller less formed creature? Like the spider head?

The Thing grows more intelligent the more biomass it acquires. For example, a Thing the size of a cat wouldn’t be very smart. But a man-sized Thing would be much more conniving

Don't be rude. It's very unattractive. Plus, the scene with Windows proves even killing one human isn't very easy.
Yep, Windows was still moving. The Thing is surrounded and at a disadvantage because he was tied up and had a flamethrower aimed at him. Yet, it still took over 30 seconds to kill Windows rather than finish him off "extremely easy" and attack either MacReady or any of the tied up people. And even after that, Windows wasn't dead or fully assimilated.
So many stories, so little time.

human very easily
Hey Jerkoff a human isn't seven humans.
After nearly a minute, he was still moving.
It wasn't easy, he was still moving. LOL, are you serious with this?

Watch the language, son. No need to be rude. Even in disagreement, one can still be a gentleman.
Let's not change the subject here. No one said that.
Please don't lie. You literally said that:
I know what you're saying, but these things can kill a human very easily
It killed Windows extremely easily:
Even Windows wasn't killed very easily. After nearly a minute, he was still moving.
So many stories, so little time.

He was incapacitated and bleeding out within seconds, you blind asshole.
There's no way it'd be able to kill 7 humans "very easily."
Let's not change the subject here. No one said that.

It still took a while for Windows to die. It wasn't a quick easy kill.
Yep, struggle. It took the thing 6 minutes to kill and absorb 3 dogs that weren't even attacking it. It took so long, Childs had time to get dressed, go get the flamethrower, and then kill it. Heck, the thing wasn't even done killing or absorbing the dogs when it got fried.

OMG he was flailing?! What a warrior! He was bleeding out and going to die if he didn't turn. Stop it.
Struggled?! It was outnumbered 3-1 and not only won, but wasn't injured at all from the conflict.

Windows still wasn't dead. He was screaming and flailing and trying to fight back. It wasn't an easy kill.
Funnily enough, Windows at first was frozen in panic. Just like the Thing was as Bennings. It happens. Even to aliens.
And yes, 3 dogs. If it struggle for 6 minutes to kill 3 dogs, it'd take it even longer to kill 7 humans.
Not tougher than a human?

Dude, Windows was incapacitated in
seconds
and we're talking about 3 dogs. The only thing that defeats it is fire. Not tougher than a human? Come one!

It wasn't easy. Those scenes lasted for minutes. Heck, that dog scene alone is almost six minutes long. And it still got toasted.
So many stories, so little time.

It has teeth and tentacles galore.
It killed Windows extremely easily:
It absorbed 3 dogs easily:

It seems to be at its most vulnerable when it's in the middle of replicating. The scene with the dogs was similar. It didn't do much other than howl, and by the time it even tried to escape, it was too late. It got torched again.
I also don't think it can kill humans that easily. It had Windows by the head, and it still took a while for him to die.
So many stories, so little time.

I know what you're saying, but these things can kill a human very easily and this one just sits there and allows itself to be killed:

Whenever caught, it just stands there and screams while transforming, sometimes not even attacking. It's very panicky and dumb once identified.
To be fair, even the smartest humans can panic and act very dumb when their survival is at stake.
So many stories, so little time.

Do you think the human ones are smarter than the animal ones?

MAGA! FAFO! Schrodinger's Cat walks into a bar, and doesn't. Dumbocraps: evil people who celebrate murder.

It's a rockin' song!

Thanx.
Now i am going to have that "Dr. Zaus" in my head all day and it will drive me ape!

This was always my favorite

Yup. You know your Ape movies!

Then Conquest must have been where they kept saying "DO" and would point and the monkeys would take care of whatever the task was.

That was the final film, Battle for the Planet of the Apes.
