Limits to Natural Selection01:38

Limits to Natural Selection

33.8K
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.

Plasticity00:58

Plasticity

2.7K
Plasticity is the property where an object loses its elasticity and undergoes irreversible deformation, even after the deformation forces are eliminated. If a material deforms irreversibly without increasing stress or load, then this is called ideal plasticity. For example, when a force is applied to an aluminum rod, it changes its shape, but it does not return to its original shape once the force is removed. Plastic deformation or ductility is thus a permanent deformation or change in the...

Optimal Foraging

13.2K
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Evolutionary Psychology01:20

Evolutionary Psychology

818
Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the...

Natural Selection and Adaptation01:15

Natural Selection and Adaptation

1.1K
Natural selection, a fundamental concept in evolutionary biology, is the mechanism by which evolution is driven, favoring organisms that are best adapted to their environments. This process enhances their chances of survival and reproduction. Adaptation, a key outcome of this process, involves genetic modifications that optimize an organism's functionality under specific environmental challenges, such as extreme cold or thinner air at high altitudes.
Beyond physical adaptations,...

What is Natural Selection?01:32

What is Natural Selection?

125.2K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Area of Science:

  • Evolutionary biology
  • Ecological modeling
  • Theoretical biology

Background:

  • Performance tradeoffs are fundamental in ecological and evolutionary models.
  • Tradeoffs are often assumed rather than dynamically modeled.
  • Genetic background and evolutionary history influence tradeoffs.

Purpose of the Study:

  • To model the feedback loop where evolutionary history shapes tradeoff strength.
  • To investigate how evolving tradeoffs affect future evolutionary trajectories.
  • To bridge phenotypic models like Fisher's Geometric Model with genotypic properties.

Main Methods:

  • Development of a simple model capturing the evolutionary history-tradeoff feedback loop.
  • Analysis of how prior environmental exposure affects genome evolution.
  • Exploration of adaptation in changing or multiple environments.

Main Results:

  • Evolutionary history significantly shapes tradeoff strength and evolutionary properties.
  • Genomes with identical fitness can exhibit divergent evolutionary paths due to past environments.
  • Adaptations optimized for one environment may arise in another due to evolving tradeoffs.

Conclusions:

  • The model provides a framework for understanding evolving tradeoffs and their impact on evolution.
  • It highlights that evolutionary history is a critical determinant of adaptive potential.
  • The model offers insights into evolvability, modularity, and adaptation in dynamic environments.
