方舟子的这一观点来自侯女士的另一个证据就是，他在作于2005年1月的《答〈中国青年报〉记者刘县书的批评》中写道：HGT"是近十几年来才引起生物学界注意的遗传现象"。

It was analysed and compared to the genetic material from nearly 3,500 people; including Neanderthals, Asians, ancient Aborigines, and present-day Aborigines. It was found that Mungo Man's DNA lacked a gene that was common to all the other samples.

据分析，并通过对包括尼安德特人、亚洲人、古代原住民以及现代原住民等3500多人的遗传物质进行的比较，结果发现蒙戈人的DNA缺少一个基因。

His group extracts and sequences genetic material from fossils, and has produced DNA analyses of both mammoths and Neanderthal man.

他的小组从化石中提取基因物质并进行排列，他们现在已经得到猛犸象和尼安德特人的DNA分析报告。

This creates non-identical twins - who share on average 50% of their genetic material.

这种情况创造了非孪生双胞胎——他们共用平均50%的基因材料。

Cloning, or nuclear transfer, is a laboratory technique which gets around the need for conventional fertilisation, the union of sperm and egg which brings together two half-sets of genetic material to provide the resulting individual with a full complement of chromosomes.

克隆，或称细胞核转移，是一种实验室技术，它绕过传统的繁殖方式，即精卵结合的受精方式，后者是把两套各一半的遗传物质合在一起构成新个体的完整染色体。

Scores of dogs have been cloned using so-called somatic cell nuclear transfer, a technique for hollowing out the nucleus of a donor egg and injecting it with the donor's genetic material, which is typically skin tissue taken from the ear.

许多犬只的复制是利用所谓体细胞核转植的技术，这种技术将捐赠卵子中的细胞核挖出，再注入由捐赠犬只身上取出的遗传物质，通常是它们耳朵的皮肤组织。

Using a technique called nuclear transfer, technicians in the lab, Bill Ritchie and Karen Mycock, laboriously removed the DNA from 430 ewes' eggs, and inserted into 277 of these the genetic material from mammary epithelial cells.

实验室的技术人员Bill Ritchie和Karen Mycock运用一种称为核移植的技术艰难地把430个绵羊卵子的遗传物质取了出来，然后把源于乳腺上皮细胞的遗传物质移植到其中的277个中去。
