雞生蛋化石解密
We’ve all spent time thinking about this logic puzzle: which came first, the chicken or the egg?
我們都被問過這個邏輯問題：是先有雞還是先有蛋？
logic puzzle邏輯謎題、logical(adj.)邏輯的
Despite all the arguments, there doesn’t seem to be a definite answer.
儘管聽了很多論點，卻好像沒有一個明確的答案，
despite=in spite of儘管argument(n.)爭論definite answer絕對解答
However, a group of scientists may have found a fossil that can finally give us the answer to this question.
不過現在有一群科學家找到了一個化石能夠給這個大哉問一個滿意的解答。
fossil(n.)化石the answer to the question問題的解答
A research team from England, Sweden, China and Switzerland made a huge discovery at the Weng-an biota in Guizhou, China.
一個來自英國、瑞典、中國及瑞士的研究小組在貴州的甕安生物群中有了驚人發現。
discovery(n.)發現、make discovery=discoverbiota生物群
They found a fossil named Caveasphaera, which has provided a crucial clue to the classic logic question.
一個名為「籠脊球」的化石能為「先有雞還是先有蛋」這個邏輯問題提供重要的線索，
provide(v.)提供crucial clue重要的線索classic(adj.)經典的、classical(adj.)古典的
This round rock fossil is actually a multicellular organism dating back to 600 million years ago.
這顆圓型的化石其實是一個6億年前的多細胞結構有機體。
multicellular多細胞的organism有機體(which dates back to)date back to追溯至
The team found that the fossil is like an animal’s embryo.
團隊發現這顆化石就像是動物的胚胎一般，
embryo胚胎
They built up a model of the fossil’s life cycle with its different developmental stages, from single-cell to multicellular stages.
他們模擬籠脊球的生命週期，顯示出從單細胞到多細胞不同的發展階段，
build up建立=establishmodel模型cycle週期developmental stage發展階段single-cell單細胞
The life cycle served as evidence of animal evolution, proving that animals started from eggs.
此生命週期被視為動物演化的證據，證明動物是從蛋來的。
serve as當作=be seen asevidence(n.)證據evolution(n.)演化、發展、evolve(v.)演化分詞構句、主詞一樣
Caveasphaera recorded the key step of how animals evolved from our single-celled ancestors to today’s multicellular species.
籠脊球紀錄了動物從單細胞的祖先演化成今日的多細胞物種的演化關鍵，
record(v.)紀錄key step關鍵一步=critical pointancestor(n.)祖先species(n.)物種
It explains how a complicated creature made its way from just an embryo.
也解釋了生物如何從胚胎演變到如此複雜物種，
explain(v.)解釋complicated(adj.)複雜的make its way前進
Most importantly, the logic mystery has now been solved with a scientific answer.
最重要的是，它也為這個先有雞還是先有蛋的邏輯謎題給了一個很科學的答案。
mystery(n.)疑雲、謎題solve(v.)解開、被動scientific(adj.)科學性的
