A homoplasy evolves independently, usually due to natural selection in similar environments or filling the same type of niche as the other species which also have that trait. A common example often cited is the eye, which developed independently in many different species. 异源同形定义 另一方面，异源同形（非同源相似）是指两个或两个以上不同物种具有相同生物结构或特征，而这些物种特征不是从共同祖先那里遗传的。异源同形独立进化，通常是由于在相似环境中的自然选择或与其他具有同一特性的物种一样占据相同类型的生态位。一个常见经常被引用的例子是眼睛，它在许多不同的物种中独立发展出来。 The Difference Between Homology and Homoplasy https://www.thoughtco.com/homology-vs-homoplasy-1224821
