Evolution of New Traits in Microbes01:24

Evolution of New Traits in Microbes

197
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 Selection

30.0K
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.

Gene Evolution - Fast or Slow?

6.2K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

Hardy-Weinberg Principle01:49

Hardy-Weinberg Principle

62.3K
Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to the gene pool of the population. The gene pool of a population is the sum of every allele of all genes within that population and has some degree of variation. Genetic variation is typically expressed as a relative frequency, which is the percentage of the total population that has a given allele, genotype or phenotype.

The Evidence for Evolution02:55

The Evidence for Evolution

39.8K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Summary
This summary is machine-generated.

Epigenetic inheritance, previously seen with exogenous small interfering (si) RNA, is now shown for starvation-induced gene silencing. This acquired trait extends longevity into the third generation, suggesting Lamarckian inheritance is a key evolutionary mechanism.

Area of Science:

  • Epigenetics
  • Evolutionary Biology
  • Molecular Biology

Background:

  • Epigenetic inheritance via small interfering (si) RNA is documented in animal models.
  • Acquired traits are typically not passed to offspring through inheritance.

Purpose of the Study:

  • To investigate the inheritance of acquired epigenetic changes.
  • To determine if environmentally induced gene silencing can be inherited across generations.

Main Methods:

  • Inducing gene silencing through starvation in an animal model.
  • Analyzing gene expression patterns and epigenetic modifications across multiple generations.
  • Utilizing endogenous small interfering RNAs (siRNAs) as mediators of inheritance.

Main Results:

  • Demonstrated inheritance of a starvation-induced gene silencing pattern.
  • Observed increased longevity in the third generation progeny.
  • Showcased the role of endogenous siRNAs in transmitting acquired epigenetic information.

Conclusions:

  • Epigenetic inheritance of acquired traits, including those induced by environmental factors like starvation, is possible.
  • Suggests that Lamarckian-type inheritance of acquired characteristics is a significant evolutionary phenomenon.
  • Highlights the role of endogenous siRNAs in mediating transgenerational epigenetic inheritance.
