Does the 'Intelligent (sic) Designer' Hate Humans?

Plague Bacteria Take Refuge In Amoebae

For those who claim to subscribe to the intelligent (sic) design notion, parasitism is always embarrassing and not something they will normally bring themselves to discuss.

Take the battles medical science is having with the zika virus, the ebola virus, the malaria parasites, antibiotic resistent in pathogens, etc., for instance. If we assume for a moment that resistance to the various treatments is by design, not evolution, then one has to conclude that the designer is on the side of the parasites and is actively trying to out-manoeuvre medical science's efforts.

This study serves as a proof of principle that amoebae can support prolonged survival of Y. pestis in the environment.

Now we have the example of one of the most devastating disease organisms ever to hit mankind - the Black Death-causing Yersinia pestis - has been 'designed' to take refuge in the common amoeba which is abundant in soil and so provides a ready safe haven for Y. pestis to hide in.

Core Blimey! A Glacier Older Than Creation!

Quietly and without fuss, and quite unintentionally, science again refutes creationism.

As it often does, in fact as it almost invariably does, another piece of scientific research based on observations of the real world, incidentally refutes the primitive superstition that the Universe and Earth were created by magic just a few thousand years ago. It also refutes the myth that there was a global flood even more recently, within the written history of civilisations such as those of Ancient Egypt, China and Northern India - who all seem to have forgotten to record it or even notice that there was anything amiss.

Another Ape-Man Makes a Fool of Creationists

Homo naledi is only 250,000 years old – here’s why that matters | New Scientist

Creationists now have another problem and it's not just 250,000 year-old fossils in a 6000 year-old Universe. It's even more fundamental than that.

First, a little background:

Homo naledi is from South Africa and, like another South African hominin, Australopithecus sediba, has a mixture of very human physical characteristics and some very primitive ones. With A. sediba, the primitive characteristics are enough to place it in the Australopithecus genus and so either an ancestor of the Homo genus or a cousin of one of our ancestors.

The Little 'Hobbit' is a Big Problem for Creationists

Origins of Indonesian hobbits finally revealed:

In its slow, methodical way, science shed a little more light on one of the mysteries of the evolution of the hominid family tree - the origin of the so-called hobbit, Homo floresiensis. The remains of H. floresiensis were found in a cave in Liang Bua in the Indonesian island of Flores in 2003. Initially, they were thought to be about 12,000 years old but later analysis has pushed this back to about 50,000 years.

The mystery isn't so much now how they came to be still living in isolation up to 12,000 years ago or why they are so small, being only about 1 metre tall, but where they fit in the hominid evolutionary tree and how they got to Flores Island.

Now a team from The Australian National University (ANU) has carried out a detailed statistical analysis and

New Book With A Difference

Part of the reason I haven't been blogging quite so much in recent weeks is because I have been writing another books.

No, not another book about my usual subjects - general science, biology, atheism, religion and it's fallacies - but a much more personal book; a book about my childhood in rural Oxfordshire in the 1950s and 60s.

Of course, I cover my realisation that I was an Atheist and how my love of nature and science developed but I also cover life in general in a small agricultural hamlet. I talk about how important the countryside was to us as a playground and in particular how important the River Evenlode was to us children.

We spent the summer swimming, diving or lying half asleep with noses buried in fresh clover on the river bank and generally showing off to the local girls whose bodies were taking on strangely fascinating shapes. Some of the girls even began to wrap themselves in towels when they got changed. It was all very strange!

Give The Designer The Clap it Deserves!

Neisseria gonorrhoeae infection in the human endocervical tissue is visualized by immunofluorescence microscopy. Bacterial (red) colonization causes columnar endocervical epithelial cells to shed and lose the barrier function, which allows bacteria to enter the endocervical tissue. Frozen tissue sections were stained for immunofluorescence with specific antibodies to the apical junctional protein ZO1 (green) and N. gonorrhoeae (red) and the nuclear dye DAPI (blue).

The Intelligent (sic) Designer really does deserve a big clap! It has come up with a brilliant solution to the problem it caused by its lack of a plan!

You see, the Intelligent (sic) Designer, that imaginary being so beloved of creationists but definitely not God because that would make it religion, not science, wants to make life unpleasant for humans (for strictly scientific reasons, obviously, and nothing to do with The Fall because that's religion) so it designed nasty little organisms like Neisseria gonorrhoeae to infect them when they had sex because it doesn't like them having sex the way it designed them to.

The trouble was, in a forgetful moment, it had designed humans so they could cope with nasty little organisms like N. gonorrhoeae and not be made sick by them. Now though, it has briiantly redesigned N. gonorrhoeae so it gets around the protection if gave humans.

In an open access paper published in PLOS Pathogens today, a team of scientists led by Liang-Chun Wang of the University of Maryland, College Park, have worked out how it got around the problem it had created. It does it by exploiting the very defence mechanism the Intelligent (sic) designer designed in the first place.

Layers of Evidence Against Creationism

There is science; and there is creationism. They have nothing in common.

Science looks at evidence and bases its opinions on it. When the evidence changes, science changes its mind. How could it be otherwise when the evidence is in charge? Creationism, on the other hand, starts with opinions as dictated by a holy book and then tries to force-fit the evidence around those opinions so they look sort of sciency to the scientifically illiterate and less like irrational superstitions and magical thinking. When that fails even for the gullible credulity of creationists, the fact are simply ignored and the main problem for creationists becomes how to get away with dismissing what can be plainly seen without looking too dishonest and deluded.

Parasites Bug Creationists

Several specimens such as this Cimex latipennis female found in the Paisley Caves in Oregon date nearly 11,000 years ago.

Cimicid Remains Found in Oregon Caves are Oldest Ever Found – Entomology Today

Newly discovered bat-bugs from the floor of a cave in Oregon are the earliest so far found - and it's bad news for creationists, again.

Parasites are a problem for creationists for number of reasons and not just that so many creationists are susceptible to parasitic frauds who sell them spurious confirmation of their superstition for large amounts of money. It's no accident that so many creationist charlatans are multi-millionaires while the people they live off are amongst the poorest of people.

How Evolution Works - Squirrels and Pine Martens

Population crash in an invasive species following the recovery of a native predator: the case of the American grey squirrel and the European pine marten in Ireland | SpringerLink

Sometimes, evolution can produce intriguing and unexpected results. At first glance it may be hard to see why introducing a predator can result in an increase in the population of a species. This is especially pleasing when the species benefiting is a charming and endangered species, the European red squirrel and the predator is an almost equally beautiful member of the stoat family, the pine marten.

So, having been away from blogging for a couple of weeks with other distractions, it gives me considerable pleasure to write about this open access paper, albeit from 2014, which reports just that from Ireland.
