原來袋鼠和人有共同祖先,難怪都會直立行走ZT

大家別感到難為情了. 袋鼠挺可愛的作咱們的COUSIN也挺好的.

Scientists said they had for the first time mapped the genetic code of the Australian marsupials and found much of it was similar to the genome for humans, the government-backed Centre of Excellence for Kangaroo Genomics said.

"There are a few differences, we have a few more of this, a few less of that, but they are the same genes and a lot of them are in the same order," centre Director Jenny Graves told reporters in Melbourne.

"We thought they'd be completely scrambled, but they're not. There is great chunks of the human genome which is sitting right there in the kangaroo genome," Graves said, according to AAP.

Humans and kangaroos last shared an ancestor at least 150 million years ago, the researchers found, while mice and humans diverged from one another only 70 million years ago.

Kangaroos first evolved in China, but migrated across the Americas to Australia and Antarctica, they said.

"Kangaroos are hugely informative about what we were like 150 million years ago," Graves said.

呵呵，還不如老鼠和咱們的關係更近呢。

你的老鼠能用兩條腿跳嗎? 袋鼠還回踢腿拉.

關係遠近看分支時間的遠近，不看是否在分支后的年代里是否進化出某種略有相似的功能。有的蜥蜴也可以直立跑動呢，可它們連哺乳動物都不是。

有很多共同的基因就是有共同祖先嗎？標題是樓主加的吧？

耶穌沒有去過澳洲， 不然他會說我發現進化論。。

哦，怎麼把這句給看漏啦。那咱們真跟袋鼠有共同祖先呀，

根據進化論，所有動物都有共同祖先，很正常啊。

阿原哥們兒沒有發現進化論，但是你發展了進化論，而且現在已經是袋鼠的表兄弟了。
