Evolution Ping The List-O-Links

A conservative, pro-evolution science list, now with over 390 names. See the list's explanation, then FReepmail to be added or dropped. To assist beginners: But it's "just a theory", Evo-Troll's Toolkit, and How to argue against a scientific theory.

Maybe MSU can use this to make another Charles Rogers/sarc

[Red Badger]

I love eggs,

From my head down to my legs...........

[boomop1]

I hope when they cracked they didn't get any shell in the whites.

"Everybody be nice."

Dang...

Hmm. Reply was zapped. Try again.

The brain of the cell is in the cell wall. The DNA/RNA/genes are for reference only. This is how the fertilized egg suddenly turns into kevlar armored cell as soon as the first sperm touches it: the cell wall does the afferent and efferent thinking.

[Red Badger]

Ohhh, I hate that when it happens.........Biting down on a piece of shell is like fingernails on a chalkboard with me!.......

Wow - you hit evolution and embryonic (not really) stem cells all in one post!

[tallhappy]

Great stuff. What's interesting about mammalian oocytes and then fertilized eggs is that these sort of analyses turn up a failr amount of sequences that are species specific -- ie they don't have homologs in other species. This includes non-homologous genes even between rat and mouse, for example. Usually non-conserved sequences between mouse and human will have a rat homolog. But in these cells related to reproduction there are sequences simply not found in any other species.

Also, a large number of non-gene sequences (eg transcripts of repeat elements) are seen.

There are a lot of mysteries and the title of this is a misnomer. Biology is more mysterious than ever now because we know so much more which tells us so much we don't know.

A few years ago we wouldn't have known enough to know what we don't know.

And as far as this: Everybody be nice.

That always seems like an actual challenge or invitation to trade insults.

It's smarmy and rude.

[stripes1776]

The human egg’s ability to transform into a new life, or into new cells that may someday save lives, is well documented.

What is well documented are untested claims that embryonic stem cells may provide new therapies for various diseases.

The identification opens the way to understanding these genes’ functions, which may lead to solving problems from infertility to degenerative diseases.

The key word here again is may. But nobody knows for sure.

[curiosity]

Combined with technology, the unfertilized egg might be coaxed to produce other specific cells, including stem cells

This is great news!

[sully777]

The creator said he made them male and female according to their kind, and he made humans in his image...if so, why hermaphrodites? That's a question biblical theologians can't answer except "it's a mystery."

Glad evil scientists are actually studying and determining what makes things tick.

In the eye of the beholder.

Add me to your science ping list please PH?

Thanks mightily :)

What? No Yolks!

This is nothing to yolk about!

Biology is more mysterious than ever now because we know so much more which tells us so much we don't know.

Dang, that has got to be the quote of the day. I couldn't have said it better myself. The most fascinating thing to me about ALL fields of science, is the consistent revelation that the more we learn, the more we realize how much we oversimplified the things we didn't know before. Every time a question gets answered, it reveals several more complex questions that could not have even been conceived prior to the earlier revelation.

Science rocks.
