DNA analysis of Elapidae family of snakes shows they have an Asian origin,
not African
by Bob Yirka , Phys.org
A small team of evolutionary biologists from the University of Kansas, the
American Museum of Natural History, and the University of Helsinki, has found
that a family of snakes known as Elapidae originated in Asia, not Africa, as
many in the field have thought.
蛇蛇老家在亚洲Σ(°Д°;
(不是非洲呦！！！)
来自堪萨斯大学、美国自然历史博物馆和赫尔辛基大学的演化生物学家小组发现，一种被
称为蛇蛇科的蛇科起源于亚洲，而不是像该领域许多人认为的那样起源于非洲。
In their paper published in the journal Royal Society Open Science, the group
describes how they analyzed the DNA of 65 snake species and studied DNA data
from 434 additional species to create an elapoid evolutionary tree and what
they found by doing so.
在《皇家学会开放科学》杂志上发表的论文中，该小组描述了他们如何分析 65种蛇的
DNA ，并研究来自 434 个其他物种的 DNA 数据，以创建一棵长方形进化树，以及他们透
过这样做的发现。
Elapidae are a family of snakes (there are more than 700 species) that are
characterized by their permanently erect fangs situated in the top, frontmost
part of their mouth—and most are venomous. Well known members include
cobras, mambas, coral, mock viper and African garter snakes.
蛇科蛇科蛇科（有 700 多种），其特征是其嘴的顶部、最前部具有永久直立的尖牙，而
且大多数都是有毒的。众所周知的成员包括眼镜蛇、曼巴蛇、珊瑚、假蝰蛇和非洲袜带蛇
。
Prior research has suggested that the class first arose in Africa
approximately 25 million years ago, and from there spread to Asia, and many
other places. The team's new study has shown that such prior claims came
about due to flawed research. The team found that Elapidae originated in Asia.
先前的研究表明，该类动物大约在 2500 万年前首次出现在非洲，并从那里传播到亚洲和
许多其他地方。该团队的新研究表明，此类先前的说法是由于研究有缺陷而产生的。研究
团队发现，眼镜蛇科起源于亚洲。
The researchers noted that not enough information had been available to prior
researchers regarding the evolutionary history of the elapoid family, thus
results from such studies were suspect. To gain a better perspective, the
team studied the genomes of 65 snake species from 22 families, from 3,100
locations, and then added the genetic data they produced to existing DNA data
from 434 more species. They then used the data from all of them to build an
elapoid evolutionary tree.
研究人员指出，先前的研究人员没有获得足够的有关蛇蛇总科家族进化史的信息，因此
此类研究的结果值得怀疑。为了获得更好的视角，研究小组研究了来自 3,100 个地点、2
2 个科的 65 种蛇的基因组，然后将它们产生的遗传数据添加到另外 434 个物种的现有
DNA 数据中。然后，他们使用所有这些数据建立了一个椭圆形进化树。
In looking at their evolutionary tree, the researchers found that two snakes
represented on it, cyclocorids and mock vipers, were the first to diverge—
and because they did so while living in Asia, it strongly suggested an Asian
origin for the entire group.
在观察它们的演化树时，研究人员发现其中代表的两种蛇，即环蛇和仿毒蛇，是最先分化
的—而且因为它们在生活在亚洲时就出现了分歧，这强烈表明整个蛇类起源于亚洲。
The tree also showed that members of the family did not appear in Africa for
another 5 million years—and members of the family colonized Africa four
different times. The researchers claim that their work effectively refutes
claims of an African origin for the elapoid family of snakes—it was Asia,
they insist.
这棵树还表明，该家族的成员在接下来的 500 万年里都没有出现在非洲，而该家族的成
员曾四次殖民非洲。研究人员声称，他们的工作有效地驳斥了有关蛇科蛇类起源于非洲的
说法—他们坚称，蛇类起源于亚洲。
