I was thinking recently, about how many audiobooks are consumed by people these days. I would guess that the main reason behind this consumption is convenience. Many people just don’t have the time, or don’t create the time, to really sit down and get their head in a book. But I understand that for many, Read More…
David Coppedge extends extends Michael Denton’s illumination of the prior fitness characteristics of Earth to sustain life as we know it.
Researchers found that, “choanoflagellates made protein precursors of two mature neuropeptides, phoenixin and nesfatin.”
Scientists hypothesize that chromatin evolved in this microbe as a result of selective pressures in the primordial environment of Earth.
In an article published in Science, researchers report progress on the determination of the structure of the nuclear pore complex, “an incredibly discriminating gatekeeper for the cell’s nucleus.”
Researchers: In biology, getting rid of stuff can be just as important as making it. A buildup of cells, proteins, or other molecules that are no longer needed can cause problems, so living things have evolved several ways to clean house.
In his lengthy article, Bell draws attention to evolutionary hurdles to the origin of eukaryotic cells. The “chasm” between eukaryotic and prokaryotic cells is causing a re-think of the universal common ancestor notion.
The worldview in which Darwinism made sense will not survive quantum mechanics.
Jeff Zweerink, senior research scholar at Reasons to Believe, discusses the movement efficiency of Kinesin-1 in the context of a perceived design inefficiency in the reconnaissance aircraft SR-71.
One biologist thinks that only DNA is really a code. David Coppedge disagrees. Coppedge: But it seems fair to categorize codes separately if they contain unique information and produce unique results. Even if histones are built from DNA, once they are assembled, they no longer rely on the genetic code.
On the whole, it might be easier to conclude that the timing is somewhat off than that complex life started without oxygen. But symbiosis is an intriguing theory nonetheless.
“The fact that this increase in volume is staggered in time and transient also shows that it is an active and living system,” adds a researcher. Once again, we are expected to believe that such a system can just develop in a gradual Darwinian fashion.
In other words, contrary to expectation, the system is even more complex than supposed. At this point, unguided evolution becomes overwhelmingly implausible because it would take only one misstep to end the process. But people believe what they believe.
Researcher: “Our hypothesis is that cells might be throwing out things that are building up, toxic components or just things that don’t function properly that you don’t want to have there. It could allow the newborn cells to be born with more functional contents,” says Teemu Miettinen, an MIT research scientist and the lead author of the new study.
Coppedge: The two daughter cells face a massive organization problem. Even though they contain the same DNA code, they will take on separate roles in the cell. This means that the accessibility of genes between the two cells must radically differ.
