Uncommon Descent Serving The Intelligent Design Community


Bats are born knowing how to measure speed in time, not distance

Most interesting. But what does the professor mean when he says, "we hypothesize that an evolutionary 'choice' was made to be born with this knowledge in order to save time during the sensitive development period." So evolution is a designer that makes choices? But, as Michael Behe would ask, “How, exactly?” He can’t walk away from the problem just by putting “choice” in quotation marks. Read More ›

Moths evade bats using acoustic camouflage on their wings

As before, those who want to attribute these staggeringly complex arms races to natural selection acting on random mutations (Darwinism) are facing a huge probability gap. The processes of nature can’t be both wholly blind and highly intelligent, given time limits. Read More ›

“Moths’ ‘ears’ developed millions of years before bats” study is open access

Researchers: "We've thought for a long time that flowering plants must have contributed to the extraordinary number of moth and butterfly species we see today, but we haven't been able to test that. This study helps us see if prior hypotheses line up, and what we find is that the plant hypothesis does, but the bat hypothesis does not." Read More ›

At the Atlantic: Textbook evolution story is said to be WRONG

Hadn’t the Darwin lobby better invade and frogmarch all these little East Coast snots back into line? They must never talk in such a way as to imply that Darwinism could be wrong about anything. Read More ›

Moths use “acoustic camouflage” to evade bats

Their fuzz works like an acoustic panel to cut down the noise volume from their movements. From ScienceDaily: While some moths have evolved ears that detect the ultrasonic calls of bats, many types of moths remain deaf. In those moths, Neil has found that the insects developed types of “stealth coating” that serve as acoustic camouflage to evade hungry bats. Neil will describe his work during the Acoustical Society of America’s 176th Meeting, held in conjunction with the Canadian Acoustical Association’s 2018 Acoustics Week, Nov. 5-9 at the Victoria Conference Centre in Victoria, Canada. In his presentation, Neil will focus on how fur on a moth’s thorax and wing joints provide acoustic stealth by reducing the echoes of these body Read More ›

Bats “steal” genes from ebola-related virus

Which now seem to serve an as-yet-unknown function in the bat. From ScienceDaily: Some 18 million years ago, an ancestor of mouse-eared bats “stole” genetic material from an ancient virus related to Bola. The swiped genetic sequence — a gene called VP35 — has remained largely intact in the bats despite the passage of time, with few changes since it was co-opted, a new study finds. The research also sheds light on the gene’s possible function in bats, suggesting that it may play a role in regulating the immune system’s response to threats. “We’re using a multidisciplinary approach to understand the evolution, structure and function of a viral gene co-opted by a mammal,” says Derek J. Taylor, PhD, an evolutionary biologist at Read More ›
