Sitting on a stone wall outside, I put down a plate that had been holding a sandwich. I went back to reading my book, but when I looked up 5 minutes later, I saw that the plate had about 50 ants on it, gathering the crumbs.

Immediately, I felt a sense of revulsion. I wanted to get rid of the ants, to brush them off the plate as quickly as I could.

Why?

Instead of following my initial impulse, I simply left the plate where it was. When I came back 3 hours later, the plate was picked clean, and there were no ants on it at all.

Most ants don’t bite. They don’t carry disease.

Why do ants bother people so much?

A Year in the Life of Adam

December 4th, 2012 | Posted by Jim Cook in Religion | Science - (4 Comments)

Genesis 2:19-20 tells the story of Adam’s task:

"Now the Lord God had formed out of the ground all the wild animals and all the birds in the sky. He brought them to the man to see what he would name them; and whatever the man called each living creature, that was its name. So the man gave names to all the livestock, the birds in the sky and all the wild animals."

If you’re a believer in the literal truth of the Bible, you should be interested to know about the recent work of Camilo Mora and colleagues. The 2011 journal “How Many Species Are There on Earth and in the Ocean?” (Mora C, Tittensor DP, Adl S, Simpson AGB, Worm B. PLoS Biol 9(8): e1001127. doi:10.1371/journal.pbio.1001127) uses taxonomic estimation to determine that there are 7.77 million species of animals on planet Earth:

Table 2 From Camilo Mora et al 2011, estimating the number of species on Earth

If the Lord God brought all the wild animals to Adam to be named, all 7.7 million of them, then Adam must have been at it for quite a while. If Adam got up each and every day at 6 AM, and named a new animal every 2 seconds (try saying “Thompson’s Gazelle” in less than two seconds), not stopping until 6 PM every night, then Adam would have been at it for an entire year.

The need for speed would explain “Bonobo.”

when you make a donation to the Humane Society of the United States, you probably think that you’re helping to prevent bad things from happening to kittens, puppies and horses. That’s some of what the Humane Society does, and it’s lovely work.

However, recently, through its legislative fund, the Humane Society has also begun interfering in politics. It’s created a super PAC, and joined in to the buy-a-legislator game of unlimited political contributions in the form of independent expenditures to assist congressional campaigns.

In some cases, the independent expenditures made by the Humane Society end up having profoundly negative consequences for animals.

This week, for example, the Humane Society announced that it had spent a good deal of money to send out messages in the mail to voters in Michigan encouraging them to vote for the re-election of Republican Congressman Fred Upton. Fred Upton, it turns out, has a voting record that’s rather cruel to animals.

- Congressman Upton repeatedly votes to protect the interests of coal companies that fill in Appalachian mountain valleys with toxic waste and unleash floods of poisonous coal ash sludge across the countryside, killing countless numbers of animals
- Upton works to block safety regulations on offshore oil drilling rigs, thus encouraging more massive oil spills such as occurred after the explosion of the Deepwater Horizon rig in the Gulf of Mexico, killing and poisoning huge numbers of birds, dolphins, sea turtles and other animals
- Upton consistently votes against action to confront climate change, which is triggering a massive number of extinctions of animal species all around the world

supports anti-environmental politiciansOf course, the animals killed and injured as a result of Fred Upton’s anti-environmental agenda aren’t anybody’s pets. They’re wild animals, not domesticated and bred to have soft fur and big round eyes. Unlike the pomeranians and poodles playing in the dog park, the animals targeted by Fred Upton’s policies are hidden from the view of America’s city dwellers.

To the Humane Society, the wild animals don’t seem to matter much. To Americans who have a genuine ethical concern for the welfare of animals, rather than just a superficial attachment to captive creatures that are fluffy and cute, the independent expenditures of the Humane Society should matter a great deal.

Yesterday, in the U.S. Senate, the following senators signed their names to a bill declaring one particular species to be designated the national mammal of the United States of America:

Sen. Michael Enzi (Republican of Wyoming)
Sen. Michael Bennet (Democrat of Colorado)
Sen. Kent Conrad (Democrat of North Dakota)
Sen. John Hoeven (Republican of North Dakota)
Sen. Mike Johanns (Republican of Nebraska)
Sen. Tim Johnson (Democrat of South Dakota)
Sen. Jerry Moran (Republican of Kansas)
Sen. John Thune (Republican of South Dakota)
Sen. Tom Udall (Democrat of New Mexico)
Sen. Mark Udall (Democrat of Colorado)
Sen. Sheldon Whitehouse (Democrat of Rhode Island)

Given this list, what do you guess the proposed national mammal is? Would you make a different choice?

Your Animal Life

What is the non-domesticated animal you have the most interaction with on a regular basis? What does this indicate about your life?

Irregular Slug

January 11th, 2010 | Posted by jclifford in Science - (1 Comments)

In middle school biology, we were all taught the basic difference between plants and animals. Plants get their energy from sunlight. Animals get their energy from eating other living things.

People usually don’t learn until high school biology that there are animals, like corals, that live in symbiosis with plants. The plants live within the tissues of the animals’ bodies, and provide the animals with energy only slightly indirectly from sunlight.

We definitely were not taught that there are some animals that, after eating plants, strip out the chloroplasts from the plants’ bodies, and then transfer them to their own tissues, which then generate energy for the animals from the light of the sun. Yet, there is an animal that has been known to do just that: Elysia chlorotica, a sea slug.

That’s remarkable enough, but new research indicates that the slugs go even farther. It turns out that the slugs have been able to incorporate genetic material from plants they’ve eaten, so that now they are able to manufacture their own replacement chlorophyll to fill up the chloroplasts they’ve stolen from the algae they eat.

Furthermore, members of this species of nudibranch are born with the genes to make chlorophyll. That means that the sea slugs have managed to a small extent to re-merge the plant and animal kingdoms which diverged so long ago.

Evolution, it turns out, is even more complicated than what we learned back in our school days. It’s not just the slugs that are crossing over, either. It turns out, for example, that we human beings have snippets of viral genetic material into our own DNA.

You germ, you.

Transexualism Is Natural

March 16th, 2009 | Posted by Rowan in Religion | Science | Sex and Gender - (2 Comments)

One of the most frequent arguments right wingers make against constitutionally guaranteed equality under the law for homosexual couples is the claim that homosexuality is unnatural. Harold S. Martin of the Brethren Revival Fellowship represents this debate tactic when he writes,“It is not normal to be attracted to a member of the same sex. It violates the basic sexual structure which God created. It is a perversion. It is against nature. “

This argument has a central weakness: Homosexuality is not unnatural. Nature is filled with examples of homosexuality. Watch a troop of bonobos for a while, and you’ll see this behavior yourself. Heck, there are even cross-dressers in nature. Submissive roosters will imitate hens. Male cuttlefish will imitate females in order to sneak around competitors for some heterosexual romping.

But what if homosexuality were not found outside of human behavior? What would that mean? Computers aren’t found outside of human behavior either. Neither are socks, or toenail clippers, or prayers. So, are computers, socks, toenail clipping and praying therefore sinful? The whole church thing is definitely unnatural, except for perhaps jack in the pulpit, or maybe monkfish.

Should we build our human sexual morality just by copying what non-human animals do? Should we follow the example of a fish given the unnatural name of California sheephead. The Monteray Bay Aquarium tells us the following about the sexual life history of the sheephead: “All sheephead are born female. Most of them change to males following environmental clues we don’t fully understand.”

If we are to follow the logic of Harold S. Martin and his brethren, we should actually encourage female-to-male sex change operations. As the California sheephead prove, gender transformations are a part of nature.

But, let’s not stop there. Let’s look at other species for examples of God’s intentions for our sexual mores. The anglerfish is a highly sexually dimorphic species, in which the female is many times larger than the male. The little male finds the big female in the dark depths of the sea, then bites her and never lets go. He becomes permanently attached to her body, feeding from her bloodstream and never swimming for himself again. By Harold S. Martin’s logic, this should contribute to arguments in favor of women going out to work professionally, while men stay back at home, doing nothing except maybe watching television.

Hammerhead sharks and komodo dragon females sometimes give birth to children that don’t have any fathers. Through this process, called parthenogenesis, such complex vertebrate species are able to conceive offspring without ever having heterosexual copulation. If we think as Harold S. Martin does, the clear moral lesson about human family lives is that it is natural, and therefore acceptable, for single human lesbians to raise children on their own, without any men involved.

Homosexual male flamingo couples have been observed adopting children, so why can’t human male couples do the same? Sea hares engage in group sex. Shouldn’t we therefore do the same?

Here’s an alternative proposal: Human sexual morality ought to be based upon the best human thinking about how to deal with other people in a reasonable way, rather than by imitating animals.

Under President Obama, some things are changing, and some things are staying the same. One of the things that’s staying the same is that the Center for Biological Diversity is having to file a lawsuit in order get the federal government to comply with its obligations under the Endangered Species Act.

desert tortoiseFederal plans for groundwater development in Nevada will endanger populations of a fish, the moapa dace, and a reptile, the desert tortoise. The moapa dace was classified as an endangered species in 1967, and the desert tortoise was listed as a threatened species in 1990. Given this status for the species, the government is legally required to take action to protect their habitat. Yet, the U.S. Fish and Wildlife Service and Bureau of Land Management are taking action to threaten the habitat of these endangered animals.

That action was prepared under George W. Bush. President Bush regularly disregarded the requirements of the Endangered Species Act. Ignoring the law is something we came to expect from Bush.

However, the action is now set to go into action under Barack Obama. President Obama promised not to disregard the Endangered Species Act. Americans elected Obama because they expected him to establish a presidency that would follow the law.

So, the lawsuit by the Center for Biological Diversity is a test for President Obama. It is Obama’s Administration who will decide how to respond to the lawsuit – not the Bush Administration. Will Barack Obama choose to honor his promises to follow the law and respect the Endangered Species Act – or will Obama choose to abandon his promise of change, and slouch back into George W. Bush’s way of doing things?

Watch the way that Barack Obama directs the U.S. Fish and Wildlife Service and Bureau of Land Management to deal with the desert tortoise and the moapa dace. You may not care much about the moapa dace and the desert tortoise in particularly, but more generally, whether President Obama upholds the law when it comes to these powerless animals will indicate whether he will uphold the law when it’s your own legal rights that are on the line.
