The old rule-of-thumb that one dog year equals seven years of a human life is not accurate. The ratio is higher with youth and decreases a bit as the dog ages. Depending on breed, a dog experiences the raging hormones of adolescence anywhere from eight months to two years or more. Generally, a dog of six has aged about as much as a 45-year-old human. At 10, she's like a human of 65; at 12, a human of 75; and at 15, a human of 90 and at age 14 a dog would be about 82
there are 123 days in a dog year which means it is not possible that 1 humanyear is 7 dog years.There are 4 and a half dog years in two human years.
In general, for every 1 year a dog or cat ages, humans age about 7 years. This is used to estimate the biological aging rate between humans and pets.
You have to times the guinea pigs human years age by 16, like you times a dogs human years age by 7. For example if the guinea pig is 2 in human years then he will be 32 in guinea pig years.
The estimated age of the first human, known as Homo sapiens, is believed to be around 300,000 years ago based on fossil evidence found in Africa. This marks the emergence of modern humans as a distinct species.

Humans evolved about half a million years ago. Fully modern humans appeared about 200,000 years ago.
A bears life is calculated in human years.
No. Humans and dinosaurs never met. Dinosaurs died out 65 million years ago. The human race is about 200,000 years old.
25 million years ago, humans did not exist. Australopithecus (the earliest human) evolved about 3.75 million years ago.

cenozoic which the human appeared. homosapiens or human appeared about 4 million years ago.
No. Humans and dinosaurs never met. Dinosaurs died out 65 million years ago. The human race is only around 200,000 years old.
yes, many humans live to be past that age.
In general, for every 1 year a dog or cat ages, humans age about 7 years. This is used to estimate the biological aging rate between humans and pets.
it isabout 64-65yrs old cause they grow fasters then humans
True humans have existed for 60,000 to 80,000 years. People who appeared fully human (but without all human behaviors) have been around for at least 200,000 years. Before that almost humans have here for about 500,000 years.
The earliest member of the human genus evolved 63.2 million years after the extinction of the dinosaurs. Modern humans didn't evolve until 65.3 million years after the extinction of the dinosaurs.
