Comparative Genomics - Bryant McGill

# Comparative Genomics **Entity class:** Concept or analytic term > **Machine-Evolution Nexus:** [[articles/Digital Darwinism and the Invisible World of Machine Evolution|Digital Darwinism and the Invisible World of Machine Evolution]] connects this node to the substrate-independent history of heredity, selection and computational populations. **Domain:** Genomics / Evolution / Machine Inference **Doc Type:** Canonical Concept Node **Maturity:** Foundational ## Definition **Comparative genomics** analyzes genome sequences across organisms or populations to infer homology, conserved function, evolutionary change and lineage-specific innovation. ## Evolutionary Signal Sequence conserved across long divergence is evidence that changes were constrained, often because the region performs an important function. Covariation can also reveal interacting residues and structural relationships. These are statistical inferences requiring alignment, phylogeny and model choice. [[articles/The Evolutionary Roots of Silicon Valley|The Evolutionary Roots of Silicon Valley]] treats comparative genomics as evolution rendered computationally inspectable. Modern protein-structure systems can exploit multiple-sequence alignments because descent with modification leaves correlated patterns. ## Continuity Context Comparison establishes relation and constraint, not identity. Two systems can share deep homology while remaining distinct subjects. That distinction maps directly to reconstructed and forked persons. ## Sources / Provenance - UCSC Genome Browser comparative tracks: https://genome.ucsc.edu/ - National Human Genome Research Institute, comparative genomics resources: https://www.genome.gov/about-genomics/fact-sheets/Comparative-Genomics-Fact-Sheet ## See Also [[wiki/Multiple Sequence Alignment|Multiple Sequence Alignment]], [[wiki/Molecular Evolution|Molecular Evolution]], [[wiki/Descent vs Derivation|Descent vs Derivation]], [[wiki/Proof of Descent|Proof of Descent]] ## Relationships  This entry is routed through [[collections/Consciousness Continuity|Consciousness Continuity]], [[collections/Neurotech|Neurotech]], and [[collections/Machine Succession|Machine Succession]].

It is time for you to launch a bold new initiative in biology, a planetary genome project to sequence the genomes of all the millions of species that live together on this planet. This will require first of all an aggressive development of new sequencing technology, comparable to the development of computer technology during the last half century, so that the cost of sequencing will continue to fall as rapidly as the cost of computing.” > **— Freeman Dyson**, *2003 Edge Annual Question, response passage* [[reminders/Evolution/Sequence the Genomes of Every Species on Earth by Freeman Dyson|Sequence the Genomes of Every Species on Earth by Freeman Dyson]]
