生物

生物 (shēngwù) is "living things," and doubles as the school subject: 生物课 is biology class, 生物学 the formal discipline, 生物学家 the biologist. 生 is a sprout breaking ground in its oracle-bone form, the most life-affirming pictograph in the script, and 物 is the general-purpose "thing" of 动物 (dòngwù, "moving thing," animal) and 植物 (zhíwù, "planted thing," plant). Those two compounds split the living world exactly as Aristotle did, by whether it moves, and a zoo is a 动物园 ("moving-things garden") while a botanical garden is a 植物园.

The finer sorting stays equally transparent: 哺乳动物 (bǔrǔ dòngwù, "suckling animals," mammals), 爬行动物 ("crawling animals," reptiles), 昆虫 (kūnchóng, insects), and 微生物 (wēishēngwù, "tiny living things," microbes, the same 微 as in calculus's 微分 and the microwave's 微波). Ecology is 生态 (shēngtài, "life's condition"), and 生态环境, the eco-environment, is a fixture of policy speech.

Chinese never adopted Latin binomials into everyday speech; it names animals the way a sharp-eyed traveler would describe them. The system is old (河马 matches the Greek hippopotamus, "river horse," coined independently or by translation) and endlessly productive: when new species reach the language, they are assembled from parts. The payoff for learners runs in both directions. Seeing 食蚁兽 for the first time, you know it is a beast (兽) that eats (食) ants (蚁); knowing an animal, you can often guess its name. Some names carry small jokes: the owl is 猫头鹰 ("cat-headed hawk"), the seal is 海豹 ("sea leopard"), the dolphin is 海豚 ("sea pig"), and the turkey, that most American of birds, is 火鸡, the "fire chicken."

熊猫 (panda) hides a genuine philological argument: the mainland says bear-cat, Taiwan says 猫熊 cat-bear, and the usual story blames a 1940s exhibition label read in the wrong direction, right-to-left versus left-to-right, during the era when Chinese switched its writing orientation. Whichever order, the panda's name records a real classification puzzle; scientists argued for a century over whether the animal was closer to bears or to the red panda, and the language split the difference before the DNA settled it (bear, as it turns out).

Before Linnaeus, the script already had a taxonomy: the radical system, which files every animal character under a category head. 鱼 (fish) claims 鲸 (jīng, whale), 鲨 (shā, shark), and 鳄 (è, crocodile); 犭 (the dog radical) claims 猫 (cat), 猴 (monkey), 狮 (lion), and 狼 (wolf); 鸟 (bird) claims 鸡 (chicken), 鸭 (duck), and 鹰 (hawk); 虫 (originally "creature," now bug) claims not only insects but 蛇 (snake), 虾 (shrimp), and 蝴蝶 (butterfly). The filing reflects Han-era folk taxonomy, and its errors are informative fossils: the whale is a fish because it swims and is enormous, the bat (蝙蝠) is a bug-creature, and the crocodile a fish-thing. Biology class corrects the classification; the script keeps the receipts of the older worldview.

The bat deserves its footnote: 蝠 (fú) is a perfect homophone of 福 (fú, good fortune), which is why bats flutter across traditional textiles, porcelain, and door carvings as luck symbols, five bats together encoding the Five Blessings (五福). An animal's phonetic accidents can outweigh its zoology; the fish (鱼 yú) hangs on New Year doors for the same reason, echoing 余 (yú, surplus) in the blessing 年年有余, "surplus year after year."

The modern life-science vocabulary mixes translation strategies, and its masterpiece is 基因 (jīyīn, gene): the syllables approximate the English word while the characters mean "basic cause," a loanword that defines itself. Nothing else in the scientific lexicon matches it, though 逻辑 (luóji, logic) and 幽默 (yōumò, humor) play the same game elsewhere in the language. The workhorse terms are sense-translations: 细胞 (xìbāo, cell, "fine bladder/wrap"), 蛋白质 (dànbáizhì, protein, "egg-white substance," which is what protein was first isolated from and what the Greek root also gestures at), 病毒 (bìngdú, virus, "illness poison"), 细菌 (xìjūn, bacteria, "fine fungus"). DNA in full is 脱氧核糖核酸 ("de-oxygenated nucleus-sugar nucleus-acid," deoxyribonucleic acid rendered morpheme by morpheme), a monster everyone politely ignores in favor of saying DNA.

Evolution arrived as literature before it arrived as curriculum. Yan Fu's 1898 天演论 (Tiānyǎnlùn, "On Heavenly Evolution"), a loose translation of Thomas Huxley's Evolution and Ethics, electrified reform-era intellectuals, and its rendering of natural selection, 物竞天择 ("things compete, heaven selects"), remains a live chengyu-shaped phrase. The modern textbook term is 进化 (jìnhuà, "advance-transformation") with 进化论 for the theory of evolution, and biologists who prefer a direction-neutral word use 演化 (yǎnhuà). Darwin is 达尔文 (Dá'ěrwén), his name now attached in Chinese, as in every language, to the fact that the bear-cat and the cat-bear share an ancestor.
