侏羅紀(jì)搏擊俱樂部 第12期:叢林中的性別大戰(zhàn)

To demonstrate his intentions, the male would havebegun to perform a courtship dance.

為了說明自己的意圖雄性會(huì)開始表演一種求偶舞蹈。

CAT scan evidence shows that the brain ofMajungasaurus was incredibly small and thereforeprimitive,

CT掃描證據(jù)表明瑪君龍的大腦相當(dāng)小，

leading paleontologists to speculate that this dancewould have been very simple.

因此也很原始這讓古生物學(xué)家們猜測這種舞蹈應(yīng)該非常簡單。

Certainly, given the brain size of something likeMajungasaurus which has a relatively primitive brain,

當(dāng)然要是像瑪君龍那樣只有比較原始的大腦，

we would expect them to have the kinds of primitive, very ritualized,

我們估計(jì)它們的求偶儀式會(huì)是很原始、很模式化，

courtship rituals that we see in lizards and crocodiles today,

就像現(xiàn)代的蜥蜴和鱷魚一樣，

very stereotype, rigid kinds of courtship behaviors.

求偶行為非常模式化，比較固定。

In this theory, although the male tried his best, the female was not receptive.

不過這一次盡管雄性使盡渾身解數(shù)，雌性就是不為所動(dòng)。

Ripped from the continent of Gondwanaland by the violent upheavals of the Earth tectonicplates, the island of Madagascar was born.

由于地球猛烈的板塊運(yùn)動(dòng)，一塊陸地被從岡瓦納大陸上撕下，馬達(dá)加斯加島自此誕生。

Surrounded by sea, the island quickly became a lush green "Garden of Eden".

這個(gè)島嶼被海洋包圍，迅速地變成了繁茂的綠色伊甸園。

As evolution forged ahead, an extraordinary inhabitant emerged: Majungasaurus.

在進(jìn)化的作用下一種非同尋常的居民出現(xiàn)了：瑪君龍。

In these jungles, a colossal battle of sexes appeared to have taken place.

在這些叢林里一場性別大戰(zhàn)一觸即發(fā)。

To help to piece together a viable scenario, paleontologists have gathered as much informationabout the competitors as possible.

為了能夠拼出可能的情景，古生物學(xué)家們?cè)诒M量多地收集其競爭者的信息。

The skeletal design of Majungasaurus shows that these were very powerful animals.

瑪君龍的骨骼設(shè)計(jì)表明它們是非常有力的動(dòng)物。

But there may have been a difference in size and strength between male and female.

不過它們的雌性和雄性之間也有大小和力量的差別。

We do see some differences between the different specimens that we find in Majungasaurus.

我們的確在不同的瑪君龍標(biāo)本中看到了一些的差異。

It's hard for us to know whether there were just differences between different individuals ordifferences that we can associate to differences in sex.

我們很難確認(rèn)這僅僅是不同個(gè)體之間的差異還是我們提到的性別差異。

Both of these animal are probably fairly comparable in terms of their general size and strengthand general capabilities.

這種動(dòng)物的雄性和雌性大小、力量和一般能力相當(dāng)。
