...The fossilized embryos shatter some ideas about evolution. Not only have certain cellular processes been pushed way back in time, but also there does not appear to be any evolution seen in these embryos, since many cellular processes, including some modern features, go clear back to the beginning of the fossil record. These embryos demonstrate that complex metazoans have been around since at least the Neoproterozoic and that from an evolutionary point of view their origins go back even further. Thus, the origin of animals is firmly based on nothing, and a huge evolutionary mystery: ‘The origin of animals is almost as much a mystery as the origin of life itself.’16...

If the history of life were compressed to one day, the fossil record would begin about 8:30 pm. Lots of stuff happened before.
So at the same time celluar processes are being pushed back in time - as 'proof' of creationism - other folks are clinging to the notion that the Earth is young. Interesting coalition you have here.
The image looks more like a zygote... a collection of mere several cells. What looks modern about this? The fact that it appears to be multi-cellular?
Did you attend Cracker-Head "U"
No, Oklahoma State. Studied Geology until it became apparent a big oil bust was coming and there wouldn't be a job for me when I got done.
They still live here at Lake of the Ozarks in Missouri.
Modern features
The Late Neoproterozoic embryos
from China are complex and display
some modern features:
‘Furthermore, the embryos are
relatively complex and resemble
those of modern bilaterians such as
annelids and mollusks, but existed
tens of millions of years before the
Cambrian explosion.’10
The embryos display polar
lobes, asymmetrical bulges that allow
bilaterian embryos to form different
tissues as adults; these are common
in many modern mollusks.4 The
observations rule out an inorganic
origin and suggest the embryos are
from the same organism.10 Cell
division is asynchronous, a feature
common in modern embryos:
‘Asynchronous cell division is
common in modern embryos,
implying that sophisticated
mechanisms for differential cell
division timing and embryonic
cell lineage differentiation evolved
before 551 million years ago.’11
These findings show that, from
an evolutionary viewpoint sophisticated
processes of cell division evolved well
before the Cambrian ‘explosion of
life’. This poses many problems for
an evolutionary framework.

However, this in turn causes problems for the Young Earthers, one of whom has claimed that the pre-Cambrian fossils are not actually fossils of living creatures.
The point is not that it happened billions of years ago.
The point is that, within the framework evolutionists provide for themselves, the processes have now been pushed back in that framework well beyond what was expected by the theory.
(That is, to the extent that the theory has any real “predictive” or “expected” application).

At least he finished school and earned his degree in science. Darwin was a med-school-dropout-turned-amateur-naturalist who had the audacity to rewrite the entire history of biology based on a few minor variations between finches. And the Evos swallowed it, hook, line and sinker.
Speaking of dropouts. Did you hear what the evidence has forced the Evos to give Darwin for his birthday? The creationists have been predicting this eventuality ever since Darwin first came up with his fanciful creation myth:

Just remember, the further complex life forms get pushed back, the less time they had to “evolve.”
A funny thing happens when you find new, ancient and rare soft-bodied fossils. They can make you re-evaluate your previous premises based on other ancient and rare soft-bodied fossils. It's called science. Scientists knew of distinct elements and their characteristics well before they realized through experimentation that atoms had a tightly-packed nucleus. That discovery did not invalidate most previous research on elements and chemistry. The creationists treat every minor change in theory brought forth by additional fossil finds as invalidation of the entire theory.
In spite of all the contortions presented by evolution deniers, it is still the best “theory” presented to date.
Hmmm ... the oldest known fossil stromatolites are over 3 billion years old The Cambrian started about 550 million years ago. You just took a bite of 20 million years or so from nearly 3 billion years. Still leaves a lot of time in my book - almost 2.5 billion years, or rougly five times the time span from the start of the Cambrian to today. Hardly anything to use to triumphantly denounce evolutionary theory.
And while we are on the Cambrian, please explain why there are many major clastical families missing from its rocks. Amphibians. Reptiles. Fish did not appear until late in the Cambrian, which is rather inconvenient for claims that no evolution happened.
I was speaking of the particular “fossils” of which Stephen Gould wrote in Wonderful Life, and I’m confident that you are aware of that.
