The popular term 'mya' is replaced in scientific literature with ma (mega annum). Like the related unit bya or b.y.a., (billion years ago), mya. Mya作为英文名字该怎么发音？？谢谢/'mja / a这里是梅花音类似拼音的mia这个并不是英文单词而是英文里的里声词比如小孩不懂歌词乱唱歌就会唱 mia mia mia~

如：鱼和四角动物分离了约410mya fish and tetrapods (limbed animals) diverged about 410 mya
应该是 5 million years ago 吧 million 是百万的意思 所以是5百万年前
