survival of the fittest

Wouldn't an individually adverse characteristic "select out" on a time scale that was short compared to the time required for a species characteristic to "select in". Are teeth controlled by the aging mechanism. Not everyone is going to make it to the top. Aging drastically increases death rates for older animals because aging causes weakness, lessened agility, and more susceptibility to disease and adverse environment.

Are there any other biological functions involving biological clocks and multiple tissue types that do not involve hormones. Genetic diversity would be very poor because a few animals are having most of the progeny.

Whether any one animal survives or not is much more a matter of random chance than genetic complement. After a long time the two varieties could evolve to be so different they would become separate species. CR can apparently reverse effects of aging even if applied only late in an animal's life.

Some cancer rates could actually be increased by an anti-aging treatment which extended cell reproduction. Similarly, if you continue to over-trade and not follow an anticipatory trading plan of waiting for high-probability trade situations to set up, you are going to quickly lose money and your trading account will also die.

The second problem with Weismann's theory involved the absence of a plausible "species" benefit to aging. In this second regard, a mating ritual is more flexible than age at puberty.

Perhaps there is a fundamental limitation, a biological equivalent to the mechanical wear out process, that affects living things. Most of the fish die as fry, a few make it to the fingerling stage, yet fewer survive to become adults, one breeds.

Do you want the good life in general. Some evolved characteristic people see this as a "smoking gun" proving the correctness of their school.

The number of mature animals of any given age in the population would follow an exponential "half-life" decline with age but, statistically, the number of progeny an animal would have would increase with age.

In the antagonistic pleiotropy theory Williams,individually adverse aging characteristics are not selected out because they are inextricably associated with beneficial characteristics which have a compensating positive effect on individual fitness.

How did they escape the "inescapable biological reality". The task is now to somehow interfere with any one part of a presumably complex biological aging mechanism, without interfering with any of the other myriad mechanisms that we need to live and function. For example, nuclear background radiation could cause aging by causing increasing cumulative tissue or genetic damage.

Now the focus and genetic diversity would be fine but the death rate, selection rate and thereby the evolution rate would be half that of the first case, a severe disadvantage.

Three (known as Survival Island in the good ol' U.S. of A., which is a horrible title), is best known as that movie where Kelly Brook gets her knockers out.
