Predator-Prey Interactions02:39

Predator-Prey Interactions

21.1K
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.

The Colonization of Land02:22

The Colonization of Land

37.4K
Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

Gene Families01:57

Gene Families

9.8K
Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

What is Evolutionary History?02:35

What is Evolutionary History?

42.9K
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

Protein Families02:47

Protein Families

16.7K
Protein families are groups of homologous proteins; that is, they have similarities in amino acid sequences and three-dimensional structures. Protein families usually occur because of gene duplication, where an additional copy of a gene is inserted into the genome of an organism.   Mutations that change the amino acids but still allow the protein to be properly synthesized, will lead to new protein family members.   If these new proteins contain similar amino acids in key...

Genome Size and the Evolution of New Genes03:21

Genome Size and the Evolution of New Genes

9.0K
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.

Area of Science:

  • Population genetics
  • Stochastic processes
  • Mathematical biology

Background:

  • The Moran Model is a fundamental framework for studying genetic drift in finite populations.
  • Understanding population genealogy is crucial for evolutionary studies.

Purpose of the Study:

  • To investigate the evolution of population genealogy within the finite Moran Model.
  • To establish a novel process on binary trees representing population changes.
  • To connect finite population dynamics to existing infinite population results.

Main Methods:

  • Stochastic transformations applied directly to population genealogy.
  • Development of a process on n-sized binary increasing trees.
  • Analysis of time-reversal properties.

Main Results:

  • A new process on binary trees accurately models the Moran Model's genealogy.
  • Derived properties align with established infinite-population Moran Model results.
  • The time-reversal property simplifies state change mechanisms.

Conclusions:

  • The study provides a tractable framework for analyzing finite population genealogy.
  • The identified process facilitates deeper investigation into the Most Recent Common Ancestor.
  • Results bridge the gap between finite and infinite population models.
