Population Growth00:57

Population Growth

Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.
Evolution of New Traits in Microbes01:24

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...
Limits to Natural Selection01:38

Limits to Natural Selection

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.
Genome Size and the Evolution of New Genes03:21

Genome Size and the Evolution of New Genes

While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

Optimal Foraging00:48

Optimal Foraging

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.

Summary

Evolutionary inventions, not just innovations, drive major ecological change. These novelties create new environments and increase ecosystem carrying capacity, impacting evolutionary and ecological processes.

Area of Science:

  • Evolutionary biology
  • Paleontology
  • Ecology

Background:

  • Comparative developmental studies offer insights into morphological changes in animals and plants.
  • Understanding the establishment and abundance of novel morphologies is crucial for studying evolutionary innovation and fossil preservation.

Purpose of the Study:

  • To explore how evolutionary novelties become established and influence ecological processes.
  • To differentiate between evolutionary innovation and invention and their roles in ecological transformation.

Main Methods:

  • The study reviews existing literature on evolutionary developmental biology and paleontology.
  • It applies concepts from the history of technology (innovation vs. invention) to evolutionary biology.

Main Results:

  • Evolutionary novelties can disappear, lead to new species, or become ecologically significant.
  • Only ecologically significant novelties are commonly preserved in the fossil record.
  • Specific evolutionary inventions drive ecological transformation and increase ecosystem carrying capacity.

Conclusions:

  • Evolutionary inventions are key drivers of ecological transformation.
  • These inventions create environments for themselves and other organisms through ecological spillover.
  • The concept of "carrying capacity" in ecosystems can be expanded to include the impact of evolutionary inventions.
