BIOL 103 Lecture Notes - Lecture 1: Commensalism, Guppy, Hox Gene
Document Summary
Spread from a narrow equatorial band (break out) Local primates (including human) resistance to zika. Climate favor diversity & parasites that feed on them. Outbreak of zika first in rhesus macaque (monkeys) in platform. Represents shift of virus from host of mosquitoes species to an. More world distribution, likes to eat human. Female feed on blood to produce protein rich eggs. High frequency recessive deleterious gene for brain growth. Increases probability: recessive harmful allele being expressed in. Look at expression: how human change developmentally. Extremely rapid evolutionary change in recent human history. Flu viruses: type a, b, or c. Type c most common, mutable & epidemiologically dangerous. Don"t change rapidly (long lineages) rare, long lineages. Special concern: recombination of strains found in humans. Conferring high degree of virulence & novelty. Ex. transfer from human to animals, combine with strains of animals. More easily to recombine strains with animal"s.
