If it is evolving by variation and. Selection it can only change into a flying car, not an airplane. Just as a small mammal can change into a bat but never a bird.sure? so the car can change into an airplane for instance?

Then they are not homologous structures.
In the whale front fin, they do have a humerus, radius, ulna, carpals, metacarpals, and phalanges just like those seen in terrestrial mammals. Those same bones are not found in the front fin of sharks.
but according to evolution criteria small steps+time =big step.
so your are saying that if 2 structures shared several similar traits then they are homologous structures? if so i can say the same for the shared traits of both a tasmanian wolf and a dog:
Thylacine - Wikipedia
so they are homologous according to your critieria. right?
but they do have a trait that is very similar to a leg, and whale doesnt have this trait.
http://www.mainlesson.com/books/gibson/discovery/zpage080.gif and these structures look nothing alike to you?no, because its not a regular situation. they are also doesnt look like feets but like hands and anyone can tell the difference.
No individual changes into something they are not; the process of evolution is extremely gradual and across an entire population over generations: to see something as significant as the transition from invertebrate to vertebrate, you'd need tens, if not hundreds, of millions of years: we don't live long enough to see it. However, we have been lucky enough to see some very significant developments in some species: for example, the evolution of the digestive tract of a lizard that transitioned from being primarily carnivorous to being herbivorous. That is, over time, the most recent population is no longer remotely the same as the initial population. And this all happened because a group of these lizards got stranded on an island away from the rest of the population which didn't have their primary food source. Extreme selective pressures upon small populations can make evolution occur much faster than is typical.not realy. first- the flu virus doesnt change into something that is not a virus.
Sure it is; that herbivorous population of lizards with the carnivorous lizard ancestry are not identical organisms to their parent species. -_- also, evolution is the unifying theory of biology, and thus is related to literally anything to do with biology, so yes, virology is encompassed by evolution.so its not evolution of a new organism. and secondly- scienstis will still be able to make vaccines even if evolution was not true. so it doesnt have any connection to evolution.
There are many homologous structures between those organisms, yes. You do realize that homologous structures can be shared with organisms that aren't super closely related, right? I mean, humans share homologous structures with whales, for crying out loud.so your are saying that if 2 structures shared several similar traits then they are homologous structures? if so i can say the same for the shared traits of both a tasmanian wolf and a dog:
Thylacine - Wikipedia
so they are homologous according to your critieria. right?
Whales have the bones analogous to those in terrestrial limbs in their flippers. They aren't analogous in structure to the fins of fish. Fish fins generally are a solid bone structure (in fish that have bones in their fins), not tons of bones like in a human foot or a whale flipper.but they do have a trait that is very similar to a leg, and whale doesnt have this trait.
It's your imaginative universe, you tell me if that's how it works. To ride your analogy as best as possible, It could very well be the case that it'll turn into a flying car, even if it looks exactly like a plane. The thing is, it was a car to start with so all the car's descendants would be cars. Analogous to how Evolution works, Whales are Mammals and always will be because they're descended from what were mammals. They're also Vertebrates, Eukaryotas, etc. for the same reason. We too are mammals btw, because we too are descendants of the same mammals Whales are descended from.sure? so the car can change into an airplane for instance?
but according to evolution criteria small steps+time =big step. so according to this small steps in a regular car (its a fact that a car can get small changes over time) will change it into a flying car. even without the replication ability.
I've read a boat load of posts telling you that cars do not evolve.so do you think that small steps will not evolve into a big step in this car?
Through DNA evidence? Sure.
so your are saying that if 2 structures shared several similar traits then they are homologous structures?
if so i can say the same for the shared traits of both a tasmanian wolf and a dog:
the skull for instance.
and these structures look nothing alike to you?
"But Sarah, they are still lizards". Of course they are still lizards, evolution hasn't even been a theory long enough for us to observe any lizard population transition on the "order" classification level.
Bananas have more genes than we do too: 36,000 compared to our 20,000.
he talked about changes in genenral. not evolution. so i showed why small changes over time cant change into a big one..
But evolution specifically only occurs in biological organisms. And to change a car in to a plane would require a COMPLETE redesign of the car, even requiring starting from scratch.
