On Aging and Life Span of Human Species Based on its Evolution from Australopithecus up to Modern Human

ABSTRACT

Applying the mathematical model of vitality in human aging we have estimated the total life duration of human species and the follow up of its involution. The increase of cranial capacity during genus homo evolution and the rise of life span in different periods from ancestral times have been used as parameters. We postulated that increasing longevity negatively influences the species maintenance. The data used for calculations are supported by publications of wellknown palaeontologists.

The vitality of human species progressively increased during its evolution up to a maximum at about 3.45 million years of species age (1.3 million years ago). From that time vitality slowly declined. The species life span has been calculated between 10.1 and 11.9 million years. The results point out that the slow growth during the evolutionary process positively influences the species life duration throughout delaying the age of maximum vitality. On this basis we try to explain the extremely great longevity of the Homo floresiensis; from around 4 million years ago up to 18,000 years from now.
