But recent research has been finding ancient traces of many viruses in animal genomes , dna insertions that have likely been there for much longer than the viruses were previously thought to have existed at all .

最近的研究中，在动物基因和dna序列里找到了很多远古病毒的痕迹，表明病毒出现的时间比原来人们所认为的早得多。

Ongoing speciation , reticulate evolution , ancient relic lineages , unequal rates of evolution and disparate distributions of genetic insertions / deletions among the reconstructed primate lineages are uncovered .

在灵长类的谱系重建中揭示了大量的不间断物种形成、网状进化、古代残留谱系、不等速进化以及基因插入缺失。

When verinata first started working on its verifi nipt test , rava says , sub-chromosomal insertions or deletions -- the cause of the aforementioned so-called " deletion syndromes " -- were filed under " unknown clinical significance . "

拉瓦表示，当初Verinata公司刚开始进行其VerifiNIPT测试的时候，亚染色体的插入或缺失（也就是导致前文所述的“缺失症候群”的原因）还被列入“未知临床重要因素”。
