The Hox genes are not the big answer many thought.
Some of these areas would seem to be science issues and others only questionably so. It is much easier to get general, evidence-based agreement on what constitutes cancer and its remedies, for example, than on what constitutes selfishness and its remedies.
It would be an interesting thought experiment to consider what the oceans would be like if the formation of shells was difficult. It’s still hard to picture the idea that predation wasn’t as important as dissolution.
The new findings almost put the egg in charge of its own shape, not what anyone expected to hear.
It gets really interesting when the anti-Darwinists are not creationists but fronting various neglected ideas like epigenetics. Will they be more vicious?
Dear readers, It has been far too long since my last post, occasioned by the fact that I have entirely too many irons in the fire. I hope you will forgive this brief “drive-by” post, with a request for some help and information. One of the common refrains that comes up regarding the fossil record, […]
Note: Researchers: “It was clear from the start of the study that extinct species showed a different pattern, including species with many specializations not seen today. One such specialization is a feature known as heterodonty: regionalized differences in tooth size or shape.” Maybe the crocodiles had an arsenal of potential adaptations in their genes.
The whole story leaves one wondering what role incidental factors played, over many centuries, in the constant, reversible micro-evolution of the once-iconic Darwin’s finches.
As John Gray suggests. It’s important to know whether there is a “ghost in the human machine” vs. “crossed wires we cannot entangle” because the ghost may be acting badly. But evolution can’t go “badly wrong.” Ain’t no such animal.
Pop science media tried to spin this as an “evolution” story, which is ridiculous.
Talbott: An animal’s end-directed activity may, of course, be very far from what we humans know as conscious aiming at a goal. But all such activity nevertheless displays certain common features distinguishing it from inanimate proceedings
They’re onto something with the hair standing on end. But here are some of the other theories…
It’s an interesting theory but the obvious problem is that transmissible cancers are, as the authors admit, rare. They may always have been rare, relative, say, to predation or extinction—whether sex was part of a life form’s organization or not.
Researcher: The discovery of uncommon wiwaxiids fossils in this time frame suggests the animals lived on Earth for a far greater span of time than previously understood.
It remains to be seen whether the quest to find the new Darwin will attract the brightest lights in the world today. Honestly… why should it?
