Energy Budgets00:51

Energy Budgets

9.6K
Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...

Limits to Natural Selection

31.6K
Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.

Assumptions of Survival Analysis01:15

Assumptions of Survival Analysis

175
Survival models analyze the time until one or more events occur, such as death in biological organisms or failure in mechanical systems. These models are widely used across fields like medicine, biology, engineering, and public health to study time-to-event phenomena. To ensure accurate results, survival analysis relies on key assumptions and careful study design.

Replicative Cell Senescence02:15

Replicative Cell Senescence

3.7K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

Requirements for Human Life01:26

Requirements for Human Life

9.2K
The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

Summary

Extending human life span is a possibility, supported by studies on aging and long-lived species. Understanding the biological and evolutionary basis of aging is key to developing interventions for age-related diseases.

Area of Science:

  • Gerontology
  • Evolutionary Biology
  • Molecular Biology

Background:

  • Organismal life span can be extended through nutritional, genetic, or pharmacological interventions.
  • The goal is to slow, stop, or reverse age-associated diseases and maintain health in the elderly.
  • Models like *Hydra* spp. and long-lived species (e.g., bowhead whale) support the theoretical potential for life extension.

Purpose of the Study:

  • To discuss the biological restraints on human life extension.
  • To explore the evolutionary basis of aging.
  • To review current genetic and molecular insights into age-related decline and disease risk.

Main Methods:

  • Review of existing scientific literature on aging.
  • Analysis of evolutionary theories of aging.
  • Examination of genetic and molecular mechanisms underlying aging.

Main Results:

  • Life span extension is theoretically possible, supported by various models and species.
  • Biological restraints exist, rooted in the evolutionary basis of aging.
  • Genetic and molecular processes contribute to age-related functional loss and disease.

Conclusions:

  • Human life extension beyond current maximums may be achievable.
  • Further research into evolutionary aging and molecular mechanisms is crucial.
  • Understanding these factors can inform strategies to combat age-related diseases and promote healthy aging.
