A question about dinosaurs?

Question

I'm not sure if this should even be in this section, but I know a lot of people who've studied it come here (the evolutionists I mean).

My question is this ... if it is generally accepted that the dinosaurs were killed off by some nuclear winter of one sort or another (one theory is a big meteor, the other volcanic eruption) then how come they didn't grow back to their former size?

I mean, if the earth returned to its former state eventually, then why didn't they once again evolve? And no, I'm not questioning evolution, for I believe there were dinosaurs too, but where did they go? I can see how if they died off for lack of food supply that they would never get their size back, but if it was nuclear winter that did it, why didn't they ever come back so big again?

The reason I'm asking is I saw a Science Channel thing on this huge crocodile-looking dinosaur and wondered why they didn't evolve that way again after the ice age.

Those are some great answers, I think I see what you mean about it becoming extinct, therefore it can't exist anymore. I guess I wasn't really asking that so much as asking if the conditions are ripe once again for life, why didn't it once again evolve into large animals? Maybe not the exact same kind, but to me the beauty of evolution is the (not to sound corny but) whole circle of life thing.

You know, a life spark in the morass, to small sea creatures to land animals to plant eaters to meat eaters on up the food chain. I'm asking, WHY that didn't happen again ... does anybody know the reason? Some of you have given good theories, but I was wondering what is the accepted reason in scientific circles.

Btw, it's okay if you don't know ... I don't know either lol

Answer 1

The conditions on earth are probably a lot different now than before the ice age.

And even if the conditions were just about right in our current time, if a particular animal would become a threat to humanity, we'd certainly kill it, or invent a solution.

I honestly don't have a factual answer for this, I have far too less knowledge when it comes to science. I just wanted to tell you I like the question, and I want to read the other answers to learn about this.

Answer 2

A creature's size is directly linked to two factors; food supply and the need for strength. After the food supply shrunk (due to whatever disaster) and all the big hunters died off, the best evolutionary trait was to be small and eat less. Then whatever was left of the dinosuars evolved into birds. Crocs stayed fairly small because there were no really big creatures to eat. Then came the mammals about the same time, remember that this takes places over tens of millions of years, so the planet was changing to, not just because of a metorite or what not. The coninents seperated and created smaller, isolated landmasses for one.

Answer 3

First off, Paleontologists proved that dinosaurs exist, now not archaeologists. Secondly, the booklet of genesis does NOT clash with dinosaurs. Each day of construction is known as, within the fashioned language, 'yom'. The hebrew phrase 'yom' has more than one meanings, adding the which means for a interval of time. Thus, in the future of construction would were thousands of years. On most sensible of this, the bible states that the primary animals had been fish. As technological know-how has established, the primary animals that ever existed had been marine animals. During the following 'yom'/interval of construction the bible says God created animals that crawled in the world... why could not this have integrated dinosaurs?

Answer 4

Well, there are different christian perspectives of what happened to the dinosaurs. Some christians think they were wiped out during Noahs flood while others believe they were wiped out in Lucifers flood. Either way you beleive they were definitley here at one point. Some people believe that God created the earth and then cast Lucifer down from heaven to earth and then chaos took place on earth afterwards. Then God caused a flood on the earth (Lucifers flood) and re made the earth and then put in place Adam and Eve. It is in that time, the first earth, when people that believe this way think that the dinosaurs were and then were destroyed. Then there are those who believe that they were wiped out with Noahs flood. Either way you believe, like my pastor says at church, a second after you die it isn't going to matter so why fight over how it happened. No one really knows the answers but God. Evolutionists don't KNOW the answers but will pull out a bunch of their own theories of what happened. However I had a biology teacher tell me that so many holes could be poked in the evolution theories. This came out of the mouth of someone who you would think would conform to their beliefs.

Answer 5

Are you talking about Animal Planet with the Huge Crocodile? If you are I love that show. Where they go back in time and get the dinosaurs.

Ok, Well I am not going to be able to give you a very logical scientific explanation but I think this.............

God made all the animals first, then he made man right. So the dinosaurs were too big and powerful for man so he wiped them out and brought different animals here for us that we could live with and have power over.

Sorry, if this answer might seem too religious but I just think that it was an interesting question.

Answer 6

The dinosaurs, especially the huge ones, like brontosaurs were already dying out prior to the evolution even as smaller, quicker dinosaurs like ankylosaurs were taking over. When the mass extinction happened, the dinosaurs had already died out to a few specific groups. Mammals flourished and out competed the dinosaurs and basically the stronger group, the mammals survived.

Answer 7

The dinosaurs didn't experience a decline in population, they became extinct. When a species becomes extinct there is nothing to "grow back". Earth's entire ecology would have been altered. The species that were most adapted (or adaptable) to what that ecology changed to would have been more effective at reproduction and survival. In this case the dinosaurs were too complex/high-maintenance so they didn't survive.

Answer 8

Evolution is incredibly complex.

If a single species dies, EVERY species that depended on them WILL be effected.

60% of all life died off during hte K/T event. Dinosaurs almosta s a whole (except for birds) went extinct.

There is nothing to "come back".

Answer 9

Well, the Ice Age only lasted 3 million years, the Dino extinction was 65 million years ago, that's a lot of time to gloss over with generalizations/ignore.

Answer 10

Different conditions existed after the meteor strike - around 40% of all species world wide were wiped out. As such, with the conditions being different, evolution would have taken a different path.
