Biological Theories of Aging

If evolution encourages traits that promote the survival of the species, then why do the natural repair and maintenance capabilities of the body gradually cease to function as individuals age? And why do some animals and plants live so much longer than others? Nature demonstrates immense variability in patterns of aging across different organisms. Understanding how and why aging evolved can shed light on what drives the aging process. Is aging programmed into our genetic blueprint, or is it the result of the accumulation of damage through a lifetime of intraction with the environment? Comparative and evolutionary biology can provide some answers.

You can call her queen bee: the role of epigenetics in honeybee development

The queen and the workers receive different types and amounts of food (royal jelly only for queenie), as well as more luxuriously large cells to develop in, all of which turns on different developmental pathways. The amount of space that a larva develops in changes levels of DNA methylation. Basically, this is a way switching the DNA “off” or “on” for certain genes, without actually changing the DNA.

Aging, or senescence as it is sometimes called, is an inevitable progressive deterioration of physiological function with increasing age, demographically characterized by an age-dependent increase in mortality and decline of fecundity.
