Hello,
I'm interested in the relationship of the ratios of pregnancy length, amount of time before the infant is independent of the parent and the average life span.
For example, a dog is pregnant for 9 weeks, the puppy weens for 8-12 weeks, and then lives for 10-12 years.
Does anyone know which animals (humans included - i know it's difficult to decide when a child is independent from it's parents) have the longest/shortest pregnancy in relation to life span.
Also, which animal spends the most/least time dependent on it's parents in comparison to it's life span.
Thanks!
