Do plants evolve into other plants and animals evolve into other animals... and why don't the two twains meet?

Answer 1

Darwinism or Neo-Darwinism or what have you, generally refers to the idea that all life present on the Earth has a common ancestor… a tiny, simple, single-celled organism. I accept that evolution happens… finch's beaks change size and shape to some limited extent over time. I have no problem with evolution in that specific sense, and that is well-supported by evidence. Micro evolution is real. Call me an evolutionist if that is what is being talked about.

HOWEVER, the idea that a finch could, via the same process, become a giant purple snorklewhacker is not supported by any real evidence. It's only assumed to be true by virtue of the fact that finch's beaks change shape a little.

"Macro-evolution", which essentially refers to a simpler organism developing into a more complex organism is a whole different thing. There is absolutely no evidence of natural processes spontaneously producing the complex specified information we find in living systems. So no, I don't believe there is macro evolution ... There is no evidence for it! The two twains don't meet.

Answer 2

That question is sort of like asking why didn't your fourth cousin twice removed evolve into you? Evolution is not a straight line- it is more like a branching tree. Some organisms evolved down the plant path, some evolved down the animal plant, some evolved down the fungi path, some evolved down the unicellular organism path. Each individual organism doesn't evolve into the "next step up". Were you a bacteria when you were first born? Did you then change into a protist, then a mushroom, then a carrot, then a parrot, then a mouse, then a human? You can't look at evolution as a destination.

Answer 3

Hi....

Plants evolved millions of years ago, they were some of the very first living things on the planet.

Plants are 'still' slowly evolving....

Animals are slowly evolving too, including humans and also 'every' living thing that needs to!!


Some plants have evolved to actually look like an insect, to entice a particular insect to come to it, so fertilisation or seed/pollen spread, can take place!!

Some insects, have evolved to look like a plant, the stick insect and many others!

The Venus fly trap actually moves, to catch and digest insects....
So, in a way has evolved into a carnivore!!!

In Lancashire, in England, where the Industrial Revolution started ...
Scientists noticed that the trees had gone dark from pollution.

A particular breed of moth, that lived on these trees, also changed dark, being born darker obviously due to being able to still be camouflaged.

This proves that evolution exists!
The creature 'had' to evolve for its own existence, because its environment had changed!!

So, plants and insects 'have' evolved together!!!

Answer 4

Many hundreds of millions of years ago, life was not more complexe than single celled organisms. Eventually, due to natural selection to the environmend, some spells specialized to be heterotrophs, taking nutrition from the environment, and others autotrophs, manufacturing thier own nutrition through photosynthesis. The animal and plant kingdoms evolved from these two groups.

Answer 5

People have plants in their intestinal tract. Ecoli is a bacterium and all bacterium are plants. We are all symbiotic! People have microscopic worms in their eye lashes that clean the hairs for you! We are all part plant and part animal! Especially gwb he's more animal than human because he has so little humanity within himself!

Answer 6

It has happened in the past and such a long time expired AND one of the species probably died out.
As it is, we and chimpanzees are evolved from a common ancestor and we meet relatively often.
It MAY continue to happen if the environment alters so that we need to change but it will take such a long time that we won't even notice it.
More disastrous is the extinction of species, which IS happening before our eyes.

Answer 7

Because one is animal and one is vegetable. The do evolve in relation to each other (ie. bees polinating flowers, etc) but they cannot become each other because they are completely different things to begin with. The only real similarities is that are both alive and they both evolve, otherwise they are as different as water and stone.

Answer 8

Because the tree of life branches outward... and each branch either terminates or splits into more branches. Though branches might occasionally cross... they never converge.

And two root branches so far apart as animals and plants clearly cannot reconverge.

Answer 9

They actually DID, in the very early days of life on the planet.

Nowadays, though, there are just too many difference that have accumulated over millions of centuries...

Answer 10

Well, there are the plankton. They still seem to straddle the gap between plant and animal life.

But personally, my favorite example is Oddish. ;)
