Summary
Ecological evolution is not a one-way street. Adaptive evolution in species, like sticklebacks, can actively shape their environment, challenging long-held scientific beliefs.
Area of Science:
- Ecology and evolutionary biology
- Environmental science
Background:
- A prevailing concept in ecology and evolution posits that environments are passive, external forces.
- This perspective overlooks the reciprocal influence of species on their surroundings.
Purpose of the Study:
- To challenge the traditional view of the environment as a static, extrinsic factor.
- To explore how adaptive evolution can actively modify ecological systems.
Main Methods:
- Investigating life history evolution in stickleback populations.
- Analyzing community ecology dynamics within stickleback habitats.
- Examining speciation processes in relation to environmental feedback.
Main Results:
- Evidence suggests that stickleback adaptive evolution influences their ecological communities.
- Observed changes in life history traits correlate with environmental modifications.
- Speciation patterns indicate a role for reciprocal interactions between species and environment.
Conclusions:
- The adaptive evolution of species can significantly shape their environment.
- This challenges the long-standing ecological dogma of the environment as solely an extrinsic force.
- Reciprocal interactions between species and environment are crucial for understanding ecological and evolutionary processes.

Cell Signaling Feedback Loops
7.9K
Positive and negative feedback loops are crucial for regulating biological signaling systems. These feedback loops are processes that connect output signals to their inputs.
Negative feedback loops
Most signaling systems have negative feedback loops that can perform different functions such as output limiter, and adaptation.
Output limiter
Upon receiving an input signal, the cellular response rapidly increases until a threshold is reached. Beyond this threshold, a negative feedback loop...

Positive and Negative Feedback Loops

Animal organs and organ systems constantly adjust to internal and external changes through a process called homeostasis ("steady state"). Examples of these changes include regulation of the level of glucose or calcium in the blood or internal responses to external temperatures. Homeostasis requires maintaining an internal dynamic equilibrium:

Predator-Prey Interactions
22.2K
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

Feedback Loops

In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

Evolution of New Traits in Microbes

Microorganisms evolve rapidly due to their large population sizes and short generation times, often exhibiting measurable changes within days under laboratory conditions. Natural selection acts on standing genetic variation, enabling the retention and amplification of beneficial traits that confer fitness advantages in changing environments.Adaptive Pigment Regulation in RhodobacterIn Rhodobacter, a genus of purple non-sulfur bacteria, light-harvesting pigments such as bacteriochlorophyll and...

Evolutionary Psychology
1.2K
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...
