Has an existing species ever given birth to a new species, like has a polar bear......?

Question

ever given birth to a grizzly bear, or a panda bear? is evolution simply adaptation, or what? did a monkey give birth to a human?? or did early humans just adapt to and keep adapting to their enviornment, what am i missing?

and no, this doesn't mean i think the earth is 6,00 years old, whew

Answer 1

Adaptation can be seen all around, you're right. Of course horses breed with donkeys and produce mules. The problem is that mules cannot breed with other mules. Otherwise I don't know of any successful, ongoing species having been born from another species.

Answer 2

I think that both Christianity and Scientology have an excellent point: The world was created in 6 days and that de-evolution rather than actual evolution occurred within hours.

God created man from dust and aliens basically inserted those seeds in the ground. Adam gave birth to a live female fetus, which can only make sense because man is God's creation and a woman's body is an illusion or so other people thought. Women were made entirely out a man's rib which makes sense because they can give birth and theoretically men can do so too since God initially gave man a uterus.

Answer 3

Yes, my presumption is that in order for life to evolve from a less-than-one celled system to some of the higher life forms on the planet, due to the particulars of the mechanisms involved, some of the mostly gradual change occuring on any particular "branch" of the tree is going to be dramatic change... for example, mammals have a certain number of chromosomes, whereas plants have another. Obviously sometimes that number must change at least once on all or nearly all of the branches of the tree of evolution. Those changes will probably be dramatic.

if you look at the tree of life, you can try to guess at what the changes must have been like, or when they occurred. Here is the tree of life:

it looks like God got the order of the animals wrong when he penned the bible.

Answer 4

A polar bear isn't a species, it's an organism. Evolution is differential adaptation by organisms, resulting in changes in allele frequencies over generations.

And every organism is a so-called transitional form. In the case of extant species, we just can't know what it's transitioning to.

Answer 5

no..of course not and never..evolution isn't that..evolution is caused by the genetic variation in gene pool..in most biology books explain about evolution..should read one..for the foundation course syllabus..i left that subject for months..but i am sure that is not possible for one polar bear to evolve into a grizzly..it takes a muchx1000000 longer time for a polar bear to evolve into a grizzly(if it's possible though..)that's all i know..

Answer 6

I am studenf of biology. In Embrylogy if you study it you find that all living things have the same protcess of growing as embry and in the first stage of growing the similarity are more.

But all of this can not disprove that God don't exist.

God exixst even when non believes don't belive in God.

Answer 7

Yes. Mutations happen all the time. But they are very small so they don't actually LOOK different for hundreds of thousands of years.

Answer 8

Never.

It would require centuries of adaptaion for such a thing to occur, unless mated strategically.

Adaptation is real, evolution is a fairy tale.

Answer 9

Gradual change. That's the definition of evolution.

Answer 10

Yep. There are ligers and tigons, crosses between lions and tigers. All were genetically engineered.
