Document Summary

Molecular evolution is the process of evolution at the scale of dna, rna and proteins. Genetic tool box: tools used to increase diversity: mutations, recombination, reassortment. Evolution of dna, rna, genes, genomes, biochemical pathways and proteins. E(cid:448)olutio(cid:374) is a (cid:862)u(cid:374)ifyi(cid:374)g s(cid:272)ie(cid:374)(cid:272)e(cid:863) that allo(cid:449)s for (cid:272)o(cid:373)pariso(cid:374)s a(cid:373)o(cid:374)g different organisms, or mechanisms (replication, transcription, translation, genomes, ect) Evolution provides a scientific explanation for life. Example: origin of hiv and aids: aids = acquired immunodeficiency syndrome. Comment: pandemic is an epidemic (outbreak of an infectious disease) that spreads across a large region. Infectious disease that may be transmitted from other animals, both wild and domestic, to humans or from humans to animals: ex. Smallpox (virus: variola major and variola minor: evolutionary origin rodent virus) Colonization: introduction of a new pathogen 1520 introduced by european conquistadores: decimated north and south american native populations. Note: smallpox even in the 20th century millions perished.
