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.

蛇蛇老家在亞洲Σ(° Д° ;
(不是非洲呦！！！)

來自堪薩斯大學、美國自然歷史博物館和赫爾辛基大學的演化生物學家小組發現，一種被
稱為蛇蛇科的蛇科起源於亞洲，而不是像該領域許多人認為的那樣起源於非洲。

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《皇家學會開放科學》雜誌上發表的論文中，該小組描述了他們如何分析 65種蛇的
DNA ，並研究來自 434 個其他物種的 DNA 數據，以創建一棵長方形進化樹，以及他們透
過這樣做的發現。

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 多種），其特徵是其嘴的頂部、最前部具有永久直立的尖牙，而
且大多數都是有毒的。眾所周知的成員包括眼鏡蛇、曼巴蛇、珊瑚、假蝰蛇和非洲襪帶蛇
。


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，該類動物大約在 2500 萬年前首次出現在非洲，並從那裡傳播到亞洲和
許多其他地方。該團隊的新研究表明，此類先前的說法是由於研究有缺陷而產生的。研究
團隊發現，眼鏡蛇科起源於亞洲。


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.

研究人員指出，先前的研究人員沒有獲得足夠的有關蛇蛇總科家族進化史的信息，因此
此類研究的結果值得懷疑。為了獲得更好的視角，研究小組研究了來自 3,100 個地點、2
2 個科的 65 種蛇的基因組，然後將它們產生的遺傳數據添加到另外 434 個物種的現有
DNA 數據中。然後，他們使用所有這些數據建立了一個橢圓形進化樹。

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.

在觀察它們的演化樹時，研究人員發現其中代表的兩種蛇，即環蛇和仿毒蛇，是最先分化
的—而且因為它們在生活在亞洲時就出現了分歧，這強烈表明整個蛇類起源於亞洲。

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.

這棵樹還表明，該家族的成員在接下來的 500 萬年裡都沒有出現在非洲，而該家族的成
員曾四次殖民非洲。研究人員聲稱，他們的工作有效地駁斥了有關蛇科蛇類起源於非洲的
說法—他們堅稱，蛇類起源於亞洲。
