Evolution Disease 1 Flashcards
Lundehund
scramble up cliffs to find puffin nesting burrows on Lofoten islands in Norway
Health problems in prebred are now common as a result of inbredding which you know from pop genetics (delterious alleles)
Artificial Selection
human mediated evolution
Intentional
desired traits are selected by breeding organisms with those traits
- domesticated animnals
- domesticated crops
Unintentional
evolution can also occur in response to other human activities
- hunting/fishing
- infection disease
- agricultural pests
Non communicable diseaases
combination of genetic and environmental cause cannot be transferred between indiviudals
Genetic disorders
not diseases
Infectious diseases
caused by pathogens like viruses, protists, and bacteria.
Penicilin
first antibiotic to be idolated
Antibiotic resistance
- high mutation rates
- Strong selection
- Fast generation tomes
- Horiztonal gene transfer
high transmission to a new host - Bacteria can evolved resistance and can evolve ina single patient
Contributors to antibotic resistance
one solution is decreasing the rate of antibiotic resistance maybe be to lower the rate of antibotics used.
Many of our internal bacteria have important functions
Antibiotics are relatively non specific so they reproduce beneficial bacteria too.
