Specialization, Speciation, And Radiation: The Evolutionary.

特殊化，物种形成，辐射。

Issue regarding the Homo sapiens speciation and evolution has been intensively and extensively focused on.

摘要人类的物种形成与进化问题一直是研究的一个焦点.

2005 was also a standout year for researchers studying the emergence of new species, or speciation.

2005年也是研究新物种出现，或称物种形成，的科学家们作出杰出工作的一年。

Often cited examples of sympatric speciation are found in insects which become dependent on different host plants in the same area.

经常提到的同域物种形成实例，是在同一地区的、依赖于不同寄主植物的昆虫中发现的。

The result indicated that speciation ofallopolyploid wheat induced rapid and extensive genetic and epigenetic changes in thegenome.

结果表明，小麦异源六倍体物种形成诱发迅速且广泛的基因组遗传变异和表观遗传变异。

Researchers usually link speciation to some sort of physical barrier, such as a river or mountain, which divides populations and causes them to evolve independently.

研究人员通常把物种形成与某种物理屏障相联系，如河流或山脉，这种屏障分隔种群，使它们独立进化。

Indeed, many think that regulatory changes are at the heart of speciation and may have played a large role in the evolution of humans from their predecessors.

确实，许多人相信调控方面的变化处于物种形成的核心，可能在人从其祖先的进化历程中扮演了一个重要角色。

Speciation can result from geographical separation or ecological specialization.

从形态可能导致分居或生态地理专业.

The results show that the most speciation is residua and the least speciation is ion exchange.

研究发现,各重金属的形态以残渣态为主,离子交换态含量很少.

This is what we would expect if speciation takes a long time.

这是可以理解的，若成种作用需要很长时间的话。
