# 编者信息 熊荣川 明湖实验室 xiongrongchuan@126.com http://blog.sciencenet.cn/u/Bearjazz Intraspecific gene evolution cannot always be represented by a bifurcating tree. Rather, population genealogies are often multifurcated, descendant genes coexist with per ...
# 编者信息 熊荣川 明湖实验室 xiongrongchuan@126.com http://blog.sciencenet.cn/u/Bearjazz As sequences diverge over time, the observed number of changes underestimates the real number of changes. Imagine a nucleotide that begins as A. In one linea ...
# 编者信息 熊荣川 明湖实验室 xiongrongchuan@126.com http://blog.sciencenet.cn/u/Bearjazz A homoplasy is a character shared by a set of species but not present in their common ancestor. A good example is the evolution of the eye which has originated independen ...
# 编者信息 熊荣川 明湖实验室 xiongrongchuan@126.com http://blog.sciencenet.cn/u/Bearjazz Divergent and Convergent Evolution Homology is a product of divergent evolution. This means that a single ancestor species split, or diverges, into two or more species a ...

# 编者信息 熊荣川 明湖实验室 xiongrongchuan@126.com http://blog.sciencenet.cn/u/Bearjazz Two common terms used in the science of evolution are homology and homoplasy. While these terms sound similar (and indeed have a shared linguistic element), they are quit ...
