DEVELOPMENTAL QUANTITATIVE GENETICS AND THE EVOLUTION OF ONTOGENIES.
1Department of Genetics, North Carolina State University, Raleigh, NC, 27965-7614.
Summary
This study introduces a quantitative genetic model integrating developmental traits into evolutionary morphology. It examines how developmental processes influence evolutionary change, including pleiotropy and heterochrony.
Area of Science:
- Evolutionary biology
- Developmental biology
- Quantitative genetics
Background:
- Evolutionary change in morphology is traditionally studied through genetics.
- Integrating developmental processes offers a more comprehensive understanding of evolutionary mechanisms.
Purpose of the Study:
- To present a quantitative genetic model for integrating developmental information into evolutionary morphology.
- To explore the evolutionary implications of developmental processes like ontogenetic trajectories.
- To analyze the origins of pleiotropy, developmental constraints, and heterochrony.
Main Methods:
- Development of a quantitative genetic model describing trait development via ontogenetic trajectories.
- Analysis of evolutionary aspects of development using the proposed model.
- Examination of genetic maternal effects in mammalian development.
Main Results:
- The model allows for the integration of developmental data into evolutionary genetic discussions.
- It provides a framework for understanding how developmental parameters influence evolutionary trajectories.
- Key developmental phenomena such as pleiotropy, constraints, and heterochrony are examined.
Conclusions:
- The presented model offers a novel approach to studying evolutionary morphology by incorporating developmental aspects.
- Understanding developmental origins is crucial for explaining evolutionary changes in complex traits.
- Genetic maternal effects play a role in mammalian developmental trait selection.

02:05Gene Evolution - Fast or Slow?
8.3K
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.

03:21Genome Size and the Evolution of New Genes
9.3K
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.

02:55The 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.
