Have 99% of All Species Gone Extinct?

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, or regarding claims about biodiversity and the evolution of species more generally, is that the vast majority of species that have ever lived on the Earth have gone extinct. This is often phrased as “99% of species that have ever lived have gone extinct” or similar wording. (Occasionally someone will temper the number to 98% or 95% or some other nearby figure, but 99% seems Read More ›

Atheism’s problem of warrant (–> being, Logic and First Principles, No. 23)

Atheism seems to be on the table these days here at UD and a few points need clarification. First up, what is Atheism? The usual dictionaries are consistent: atheism n. Disbelief in or denial of the existence of God or gods.

Researchers: Comatose people do show self-awareness

Michael Egnor: This study is consistent with the work of Wilder Penfield, who showed that higher-level abstract thought did not seem to arise from the brain in a material way. Read More ›

Vegetarianism arose three times in extinct crocodiles. Maybe six.

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. Read More ›

Paley’s Ghost speaks out: the problem of [neo-]darwinist evolutionary incrementalism

One of the common weak arguments against the design inference on functionally specific, complex organisation and/or associated information (FSCO/I, a functional form of specified complexity) is the idea that body-plan level macro-evolution is “simply” the accumulation of lots and lots of micro-evolutionary adaptations in a grand climb of fitness. It seems to be back on the table, so let us highlight its fundamental flaw through an infographic: Notice, how easy it is to trap a process that depends on loose-sense hill-climbing. Where, too, the FSCO/I origin challenge can be similarly summarised: That fitness peaks will naturally occur as islands of function amidst vast seas of non-function should be obvious from the need for correct, matched, properly arranged and coupled parts Read More ›

Michael Egnor takes on buzzwords about “neural networks”

"In reply to my observation that the results of many of the most important experiments in modern neuroscience are most consistent with the dualist, and not the materialist, understanding of the mind, commenter Ali [at Peaceful Science], who describes himself as an “anti-creation psychiatrist”, sniffs: “Rubbish” … " Read More ›

Feynman, says Massimo Pigliucci, is wrong about beauty and truth in science

Massimo Pigliucci: But as the German theoretical physicist Sabine Hossenfelder has pointed out (also in Aeon), there is absolutely no reason to think that simplicity and beauty are reliable guides to physical reality. She is right for a number of reasons. Read More ›
