the age of a dog in human years is much more than first , claim.
科学家说,计算狗狗的年龄相当于人类的几岁时比我们一开始想的单纯乘以7要复杂。
The idea that a dog’s age in human years is its age times seven ‘is a myth’, to from the of .
根据加州研究者的说法,把狗狗年龄乘以七作为人类年龄的想法来源还是一个谜。
They have a new for the age of a dog to a human, based on the rate that are added to DNA.
他们基于加入DNA分子的比率,创造出了一个新的公式来转化狗狗和匹配的人来年龄的公式。
The team, led by Tina Wang, say it isn’t easy to come up with a true the age of a dog and a human as they reach at rates and dog have life spans.
研究小组是由遗传学专家Tina Wang领导的,她说:“把狗狗的年龄换算成人类相当的年龄可不容易,因为他们的成熟时间不同,不同的狗寿命长短不同。
The looks at to DNA over time, to the ‘ ‘, which are that add to DNA at a rate.
这个公式着眼于DNA随时间的变化,特别是“甲基原子团“,它们是以一致的速率加入DNA的分子。
Dog vary from 6-7 years for breed to up to 18 years for dogs but, the , they have a .
大型犬的寿命在6-7年,小型犬可达18年,但是他们的生命长度不同,生理轨迹也不同。
They found in the of major dogs and .
他们发现狗狗和人类在主要时间节点上有相似之处。
The were when age dogs and were .
基于狗狗和人类年龄上面的比较,相似之处还是比较明显的。
The new , based on the clock the of a dogs age, it by 16 and then 31 to the total.
基于后天生成生物钟的新公式,是把狗狗的实际年龄的自由对数狗年龄,乘以16再加上31.
Using this an 18 year old dog would be 77 and a 2 year old dog would 42 in ‘human years’.
用这个公式算出18岁的狗相当于人类的77岁,而2岁的狗相当于人类的42岁。
The team did find that there were in the life of dogs where the didn’t match , as they in their than .
在狗的一生中狗年龄,有一些时期的生物钟状态与人类不匹配,就包括青春期,因为它们比人类生命周期更早成熟。
say even with the , their is still more than the ‘dog age plus seven myth’.This has been on .
研究人员说尽管有青春期的问题,但是他们的公式比单纯的乘以7来换算两者间的年龄还是要准确很多的。研究结果发布在了上面。
