留美老師帶你每日說英文 第389期:左撇子是遺傳的麼?
臺灣籍旅美老師今天交給我們的句子是：
And despite what many may think, handedness is not a choice. It can be predicted even before birth based on the fetus' position in the womb. So, if handedness is inborn, does that mean it's genetic?
而且，與大多數人所認爲的相反，要用哪隻手不是我們選擇的。它甚至可由胎兒出生前在母體的胎位預測出來。那如果用哪隻手是與生俱來的，意思是那是遺傳的嗎？
