Barbarian observes:
Just pointing out the error of saying "we can't directly observe anything that takes that long to happen, so it can't happen."
That's a reasonable statement.
Right. That's why the YE argument falls apart.
But the other side of that coin is that an infinite amount of time doesn't make the impossible happen!
Comes down to evidence. And, as you learned, it's abundant and diverse.
Barbarian observes:
You've gotten confused again. No algae gave rise to land plants. Rather, some specialized freshwater plants seem to have been the immediate ancestors of land plants. But of course, they didn't give rise to redwoods, either. They came much later.
(doesn't know what to say)
It's not surprising. Few people know much about the classification of plants in oceans or lakes.
Ever heard such tripe as this:
Probably an algal scum formed on land 1,200 million years ago. In the Ordovician period, around 450 million years ago, SHAZZAM! the first land plants appeared.
You see it a lot on creationist sites. As I said, it's because most creationists have no clue about the evidence. To anyone not familiar with science, much of nature looks like magic. In fact, the simplest land plants known are not all that far removed from water plants that in turn look a lot like colonial forms of algae.
However, additional phylogenetic dilemmas are the evolution of bryophytes from algae and the transition from these first land plants to the pteridophytes.
Well, that's a little behind the time. The earliest known land plant, Cooksonia, lacks leaves, roots, and most other land plant features, but has xylem. So it's a nice intermediate between extremely primitive land plants like liverworts (which are byrophytes) and horsetails (which are pteridophytes).
All these very large evolutionary jumps are discussed...

Hmm... they need to update that, um?
You get the impression that they don't have a clue?
Hard to keep up on everything, I guess...
Another problem for land plants is that they miss the upward force of the water. To be able to keep upright supporting tissue is needed. Already in Cooksonia xylem vessels have been recorded. These are vessels with annular or spiral shaped thickenings at the walls, which give them solidity. Through these vessels water is transported from the soil to the plant cells.

If you're starting to get the feeling that there's an intermediate for everything, you're on the right track.
Land plants probably evolved SHAZZAM! from marine plants, moved into freshwater SHAZZAM!and finally SHAZZAM! onto land.
To the ignorant, it must appear so. But as you see, that's not the case.
So I'm right. Sequioas did evolve from seaweeds or something like it.
Nope. From more primitive conifers. You've been misled again.
Barbarian observes:
In fact, every seed will produce a tree slightly different than the parent. That's how it works.
If you prefer "descent with modification", that will do. It's what Darwin called it.
Er, no. I call it 'variation'.
Darwin called it variation, too. His discovery was that variation, over time, accumlates.
But whatever Darwin called it, you haven't answered the question. Can I confidently expect a few pear trees in my population of apple trees in a zillion years time?
If they survive as a lineage, and humans don't keep selecting them to be apple trees, they will change to something else.
Barbarian observes
What God did, was make variation the way things are. And over time, variation and natural selection produce the diversity of life.
God created all this diversity
Yep. You just don't approve of the way He did it.
and the variation we see was built in.
Nope. Organisms can have at most, two alleles for every gene locus. All the other (usually scores of them) alleles in populations evolved by random mutation and natural selection.
Barbarian observes:
Geneticists say they had a common ancestor, actually.
Geneticists can say what they like - but cold, hard, nasty facts are what I want.
You get pretty cranky whenever I start citing evidence.
Observable and observed proof. Luther Burbank should have shut them up
Burbank denied Mendel's discoveries. He didn't believe in genes or the nature of dominant and recessive traits. This led him to the classic anti-Darwinian philosophy of human eugenics.
Most historians gloss over this distasteful eugenical aspect of Burbank's work, preferring instead to amplify and expand the prodigious mythology surrounding Burbank, the "genius gardener" His eugenic philosophy forms an unsettling inconsistency with the public legend that California journalists, politicians, his chroniclers, and not least of all, Burbank himself, created...In the early life of the eugenics movement in America, California and Luther Burbank led the way. In his 1907 book, Training the Human Plant, Burbank said:
It would, if possible, be best absolutely to prohibit in every State in the Union the marriage of the physically, mentally and morally unfit. If we take a plant which we recognize as poisonous and cross it with another which is not poisonous and thus make the wholesome plant evil, so it menaces all who come in contact with it, this is criminal enough. But supposed we blend together two poisonous plants and make a third even more virulent, and set their evil descendants adrift to multiply over the earth, are we not distinct foes to the race? What, then, shall we say of two people of absolutely defined physical impairment who are allowed to marry and rear children? It is a crime against the state and every individual in the state. And if these physically degenerate are also morally degenerate, the crime becomes all the more appalling".

Darwinians like Punnett and Morgan showed that Burbank's ideas were scientifically wrong, and Darwin himself said such thinking was "overwhelming evil." But the Geneticists' warnings fell on deaf ears and the Holocaust was one of the consequences.
but some people don't learn, do they, Barbarian?
Belatedly, they did. After over a hundred million deaths.
Barbarian observes:
Horses are a recent example, as are birds from reptiles and tetrapods from fish.
C'mon, you learned about this earlier. You know better than that.
Go look up what Eldredge said about the horse exhibit in his museum. I won't quote mine him.
Good. What Eldredge says is that horse evolution was not a straight tree, but a branching bush. He criticized the museum for only showing one branch, the surviving branch. Surprise.
Barbarian:
Sure. Here's Archaeopteryx, along with a modern bird and a small theropod dinosaur. Your assignment is to classify it as a bird or a dinosaur, and tell us how you made the decision.
There are no soft tissues. Without such important data, I cannot make the classification
Sure you can. Any high school biology student can. Soft tissues are not required to separated mammals and reptiles. The single defining point is skeletal.
No more stalling. Make your choice. And tell us how.
You do remember the coelacanth debacle, don't you?
Yep. The gullible thought that the modern coelacanth was the same as ancient ones. And as you learned, they are highly evolved from ancient ones.
Barbarian observes:
Here's another transitional. Your job here is to tell us whether it's a mammal or a reptile, and how you decided:
How much of this is plaster of Paris?
None at all. It's a CAT scan of a real fossil. No more stalling. Make your decision and tell us how you decided.
Barbarian observes:
Evolutionary theory is consistent with our descent from a single pair of humans.
Can't think of any better example of a common ancestor.
(Async tries the old "male and female" gambit)
Barbarian chuckles:
I think that it's a mistake to take that too far. God makes it very clear in Genesis what was there at the beginning, and male and female were not. Jesus meant "from the beginning of the human race" which began with two humans. Which species, I do not know, nor does it matter.
As I said, it's Homo sapiens without doubt.
Barbarian asks:
You don't think H. neanderalis was human? H. erectus? H. ergaster? Seriously?
(declines to answer, again)
Would you be offended if I asked you to learn a little about the subject so you could give us an intelligent answer?
