全球變暖(global warming)不僅會(huì)對(duì)地球環(huán)境造成影響,還會(huì)影響地球上所有物種的進(jìn)化(evolution)。在冰河時(shí)代(ice age),地球上的很多物種都滅絕了(extinction),幸存下來的物種成為了現(xiàn)有物種(species)的祖先。地球上的生命據(jù)有適應(yīng)性(adaptability),物種會(huì)根據(jù)環(huán)境的變化而演變,這就是所謂的適者生存。
隨著溫室氣體(greenhouse gases)的排放量不斷增加,全球不斷變暖,包括人類在內(nèi)的很多物種都在進(jìn)化的過程中。那么你知道未來的人類會(huì)進(jìn)化成什么樣子嗎?快來看看吧!
Humans may evolve bizarre features such as webbed feet and eyes like cats in response to changing environments, a scientist claims.
根據(jù)外媒報(bào)導(dǎo),一名科學(xué)家稱為適應(yīng)變化得環(huán)境,人類將逐漸進(jìn)化出奇異的特征,諸如有蹼的的腳和貓一般的眼睛。
Dr Skinner, a paleoanthropologist at the University of Kent worked with artist Quentin Devine to help visualise how humans could look in the future.
肯特大學(xué)古人類學(xué)家斯金納博士與藝術(shù)家昆特-迪瓦恩一同協(xié)作,構(gòu)想未來人們的樣貌。
Some changes could take place very quickly as some humans already have a genetic mutation that produces webbing. Other changes to allow humans to live in extreme conditions might only take place over hundreds of generations of natural selection, or require genetic engineering.
有些變化或許很快就會(huì)發(fā)生,因?yàn)橐呀?jīng)有人基因變異產(chǎn)生了足蹼。其它變化讓人們可以在極端條件下生存,要?dú)v經(jīng)數(shù)百代人的自然選擇、或是通過基因工程才會(huì)發(fā)生。
To adapt to a 'water world', Dr Skinner expects humans would develop webbed hands and eyes like those of cats to help us see in the poor lighting conditions underwater.
為了適應(yīng)“水世界”,斯金納博士預(yù)計(jì)稱人們會(huì)長出足蹼和貓眼,有助我們?cè)诠饩€微弱的水下也能看見。
Dr Skinner said eventually there could be a complete loss of teeth and a reduction in jaw and mouth size down to something you can fit a straw into, which would result in our faces becoming smaller.
斯金納博士說人們最終會(huì)完全喪失牙齒、下顎與嘴巴都會(huì)變小,小到只容得下一根麥管,臉也會(huì)因而變小。
Our noses and face size would increase to help warm inhaled cold air in the nasopharynx.
我們的鼻子和臉都會(huì)變大,以助吸入鼻咽的冷空氣變暖。
Regular foraging in shallow waters could lead us to develop artificial 'gills' to help us breathe, extracting oxygen from the water and delivering it to the bloodstream. This would also lead to our lung capacity becoming greatly reduced, and our rib cages shrinking.
經(jīng)常在淺水域覓食會(huì)引人逐步形成人工“魚鰭”以助呼吸、從水中汲取氧氣、血液循環(huán)系統(tǒng)。這也會(huì)引得肺活量大減、胸腔萎縮。
