神奇,這2種動物和人一樣有更年期範例

Most people with ovaries go through menopause. But most animals do not, and their reproductive organs last about as long as they do. We are an outlier. So are whales.

大部分有卵巢的人（指沒有被摘除）都會經歷更年期。但是大部分的動物卻不會，它們生殖器官的活性幾乎和他們的壽命一樣久。我們是個例外，鯨類也是。

"it is very strange to not carry on reproducing,"

停止繁衍對於動物來說是種非常奇怪的行爲。

In this hypothesis, an older woman helps her children's children thrive. After menopause, when she can no longer have children, she devote s her time and accumulated knowledge to aid her descendants.

這個假設是說，一個老年女性會幫助她孩子們的孩子在人生中獲得成就。更年期之後，她本人不再能生育後代了，於是她能投入自己的時間和積累的知識來幫助她的後代。

Humans "are quite far away from whatever ancestral state we evolved in," Ellis said, removed from the selection pressures imposed on bands of early humans. But these whales live in similar environments and groups as their ancestors millions of years ago, he said.

Ellis 說，人類現在的狀態已經進化得離我們的祖先很遠了，我們已經脫離了早期人類面臨的那些生存壓力。但是現在的鯨類生存的環境依舊和它們百萬年前的祖先很相似。
