Parental Care00:55

Parental Care

12.9K
Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.

Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

9.7K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

The Evidence for Evolution02:55

The Evidence for Evolution

48.9K
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.

Convergent Evolution01:54

Convergent Evolution

33.6K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

Genetics of Speciation02:16

Genetics of Speciation

22.5K
Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

Phylogeny01:23

Phylogeny

63.7K
Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.

Summary
This summary is machine-generated.

Maternal inheritance and selection impact evolution with time lags, altering evolutionary rates and directions. These non-Mendelian factors can lead to unexpected evolutionary outcomes, even maladaptive ones.

Area of Science:

  • Evolutionary biology
  • Quantitative genetics

Background:

  • Maternal inheritance involves non-Mendelian transmission alongside Mendelian mechanisms.
  • Maternal selection links offspring fitness to maternal phenotype, introducing frequency-dependent dynamics.

Purpose of the Study:

  • To develop quantitative-genetic models for trait evolution under maternal inheritance and maternal selection.
  • To analyze the impact of time lags and frequency dependence on evolutionary trajectories.

Main Methods:

  • Development of quantitative-genetic models incorporating maternal inheritance and selection.
  • Analysis of evolutionary dynamics under varying selection pressures and inheritance parameters.

Main Results:

  • Maternal inheritance introduces evolutionary time lags, causing evolution to persist after selection stops.
  • Evolutionary rates and directions can fluctuate unpredictably due to maternal effects.
  • Maternal selection can drive populations away from fitness peaks, potentially leading to maladaptive evolution.

Conclusions:

  • Maternal inheritance and selection significantly alter evolutionary dynamics compared to purely Mendelian inheritance.
  • These models highlight the complex interplay between inheritance, selection, and evolutionary outcomes.
  • Understanding maternal effects is crucial for predicting population-level evolutionary trajectories.
