Medicare and Medicaid are very different. Medicaid is a federal program for low-income, financially needy people, set up by the federal government and administered differently in each state. (This program is called Medi-Cal in California.).
1 Chimpanzees have a long mother-infant dependency period. 2  Infants will nurse on their mothers for five years and stay with their mothers several more years learning to care for younger siblings. 3  The life span for chimpanzees is 40 to 50 years in the wild and over 50 to 60 years in captivity.
Humans and chimpanzees have a different number of chromosomes. Humans have 46 while chimpanzees (and many other great apes) have 48. Current theories say that humans and chimpanzees had a common ancestor around 6-8 million years ago. This common ancestor must have had a certain number of chromosomes.
