Nature Lesson: Atlantic Horseshoe Crab
Lebanese Christians are technically allowed to eat pork, but many of them abstain, owing to the influence of their pork-avoidant neighbors in the Muslim-majority country. Like a regional dialect or a style of dress, most food taboos advertise and affirm membership within a group. Humans evolved in tribes, and food taboos helped to define coalitions. In a Hobbesian past, a cohesive tribe would have had a better chance of domination. Chimps know this just as well as high-school cliques do.
A show of strength intimidates the loners—by making them feel like losers. Our behavioral immune system, much like our biological immune system, is meant to detect danger. But it can go into overdrive. Schaller compared it to a smoke detector. When I was a child in Chongqing, in the nineteen-eighties, food forged the rules and the language of existence. To be fed was to be loved, and to live was to taste the world. When I wondered, at the age of four, if human flesh tasted like pork, it did not occur to me that the thought might be disgusting.
As a young Army recruit, my mother ate the rats that scurried outside the granary she guarded, and for years she ate kernels of rice that she found on the ground—something I was told by other adults never to do. To be the first member of my family spared the pangs of hunger was to live through an epochal transition that felt like cultural transformation. Still, the threat of deprivation hung over our lives like the dangling carcasses in the village wet markets. At those markets, my mother traded her extra grain coupons—which she began to receive after becoming an Army doctor—for eggs, an expensive protein in the hierarchy of foods. My Swiss Army knife was already being honed. Disgust welled up in me, but it contended with other blades that were necessary for survival: the shame of ingratitude, and the fear of disobedience.
I ate the brain foods every morning for two interminable years. Even so, disgust did not leave a lasting mark on my psyche until , when, at the age of eight, on a flight to America with my mother, I was served the first non-Chinese meal of my life. In a tinfoil-covered tray was what looked like a pile of dumplings, except that they were square. I picked one up and took a bite, expecting it to be filled with meat, and discovered a gooey, creamy substance inside. Surely this was a dessert.
Why else would the squares be swimming in a thick white sauce? I was grossed out, but ate the whole meal, because I had never been permitted to do otherwise. For weeks afterward, the taste festered in my thoughts, goading my gag reflex. Years later, I learned that those curious squares were called cheese ravioli. Olives were another mystery. In Chongqing, I had been introduced to them as a fig-like snack, dried or cured, that had a sweet-tart kick. In the U. To be a new immigrant is to be trapped in a disgusting-food museum, confused by the unfamiliar and unsettled by the familiar-looking. The firm, crumbly white blocks that you mistake for tofu are called feta. The vanilla icing that tastes spoiled is served on top of potatoes and is called sour cream.
At a certain point, the trickery of food starts to become mundane. Disgusting foods become regulars in the cafeteria, and at the dinner table. Recently, I joined a few Asian-American friends at a restaurant in Queens to have hot pot, a fondue-like communal meal in which ingredients are dipped in a shared pot of boiling broth at the center of the table. By the time I arrived, bowls of sliced pig arteries, pig intestines, cow stomach, duck feet, and pale-pink brains of unidentified provenance already sat around a burbling vat of broth, spices, and chili oil.
Nearly all of them named dairy products that they had tried for the first time in the United States. A Chengdu native recalled the chalky taste of a protein shake, making the classic disgust face as she spoke. It was margherita pizza, and he thought that the little white splotches of melted burrata were fresh vomit. I had had almost the exact same experience with a Sicilian slice some three decades before. Assimilating requires you to adopt a foreign tongue, in more ways than one.
But when the choice is between annihilation and assimilation, you assimilate. This was as true for prehistoric humans as it is for a young, deracinated Chinese immigrant in America. One of the wonders of the tongue is its sheer malleability. Shortly before my virtual tour of the Disgusting Food Museum, I had received a temperature-controlled package in the mail. I arranged the food in small saucers around my laptop and launched Zoom, where Andreas Ahrens was waiting for me. Before I dug in, he suggested I check that the items had made it through their transatlantic journey O. He laughed. I opened a pouch of German sauerkraut juice. Its putrid gray color reminded me of stagnant gutter water. Most try more than they thought they would. The juice tasted cool and refreshing—a blend of pickles and kimchi.
Next was bagoong, a Filipino fermented shrimp, which tasted so much like a beloved Chinese fish sauce that I was tempted to spoon it over some leftover rice. My head cocked back at the taste of ammonia, but the chewy texture reminded me pleasantly of squid. I moved on to the insects, beginning with grasshoppers from Oaxaca, Mexico, which had been marinated with dried chilies. They were delicious—crispy, sour, and spicy, like lime-tossed tortilla chips. In addition, they possess a hardened exoskeleton that is periodically shed during growth. The Nematoda or roundworms, are perhaps the second largest animal phylum, and are also invertebrates.
Roundworms are typically microscopic, and occur in nearly every environment where there is water. These groups have a reduced coelom, called a pseudocoelom. Other invertebrates include the Nemertea or ribbon worms, and the Sipuncula. Another phylum is Platyhelminthes , the flatworms. Invertebrates also include the Acanthocephala or spiny-headed worms, the Gnathostomulida , Micrognathozoa , and the Cycliophora. Also included are two of the most successful animal phyla, the Mollusca and Annelida.
These two groups have long been considered close relatives because of the common presence of trochophore larvae, but the annelids were considered closer to the arthropods because they are both segmented. Among lesser phyla of invertebrates are the Hemichordata , or acorn worms, [51] and the Chaetognatha, or arrow worms. Invertebrates can be classified into several main categories, some of which are taxonomically obsolescent or debatable, but still used as terms of convenience.
Each however appears in its own article at the following links. The earliest animal fossils appear to be those of invertebrates. Around MYA, animals began diversifying, and many of the important groups of invertebrates diverged from one another. Fossils of invertebrates are found in various types of sediment from the Phanerozoic. Carl Linnaeus divided these animals into only two groups, the Insecta and the now-obsolete Vermes worms.
They are now classified into over 30 phyla , from simple organisms such as sea sponges and flatworms to complex animals such as arthropods and molluscs. Invertebrates are animals without a vertebral column. This has led to the conclusion that in vertebrates are a group that deviates from the normal, vertebrates. This has been said to be because researchers in the past, such as Lamarck, viewed vertebrates as a "standard": in Lamarck's theory of evolution, he believed that characteristics acquired through the evolutionary process involved not only survival, but also progression toward a "higher form", to which humans and vertebrates were closer than invertebrates were.
Although goal-directed evolution has been abandoned, the distinction of invertebrates and vertebrates persists to this day, even though the grouping has been noted to be "hardly natural or even very sharp. It is also possible that some humans believe that, they themselves being vertebrates, the group deserves more attention than invertebrates. In addition, some species included are only remotely related to one another, with some more related to vertebrates than other invertebrates see Paraphyly. For many centuries, invertebrates were neglected by biologists, in favor of big vertebrates and "useful" or charismatic species. Two of the most commonly studied model organisms nowadays are invertebrates: the fruit fly Drosophila melanogaster and the nematode Caenorhabditis elegans.
They have long been the most intensively studied model organisms , and were among the first life-forms to be genetically sequenced. This was facilitated by the severely reduced state of their genomes , but many genes , introns , and linkages have been lost. Analysis of the starlet sea anemone genome has emphasised the importance of sponges, placozoans, and choanoflagellates , also being sequenced, in explaining the arrival of ancestral genes unique to animals.
