Summary
This review explores how gene regulatory networks and biomechanics interact to shape anatomical development. Evolutionary developmental biology models reveal the complex integration of genetics and morphogenesis.
Area of Science:
- Developmental Biology
- Evolutionary Biology
- Genetics
- Morphogenesis
Background:
- Anatomical structure development involves complex gene expression patterning by gene regulatory networks (GRNs).
- GRNs control effector molecules that influence cellular behavior and biomechanics during development.
- The interplay between genetics and biomechanics in shaping anatomical structures is often overlooked.
Purpose of the Study:
- To examine the intricate steps in anatomical development.
- To explore the integration of genetics and morphogenesis.
- To highlight the utility of evolutionary developmental biology model systems.
Main Methods:
- Review of existing literature on anatomical development.
- Analysis of gene regulatory networks (GRNs) and their role in morphogenesis.
- Case studies using model systems: butterfly scales, vertebrate teeth, and Drosophila dorsal appendage.
Main Results:
- Development involves a complex cascade from gene expression to biomechanical shaping.
- Feedback mechanisms between genetic regulation and physical forces are crucial.
- Model systems provide a unique perspective on the multifactorial integration of genetics and morphogenesis.
Conclusions:
- Understanding anatomical development requires integrating genetic, cellular, and biomechanical processes.
- Evolutionary developmental biology offers valuable insights into conserved developmental mechanisms.
- Further research into the interfaces between genetic networks and morphogenesis is warranted.

Gene Evolution - Fast or Slow?
8.2K
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.

The Evidence for Evolution
48.3K
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.

Genome Size and the Evolution of New Genes
9.1K
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.

Cis-regulatory Sequences
11.8K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...
