EVOLUTIONARY APPLICATIONS EQ: How does evolution affect us as humans?
3
Pesticide Resistance: Pest -icide Something annoying (like an insect!) To kill Pesticide:chemicals that kill insects Resistance:Not affected by something Pesticide resistance: An insect does not respond to pesticides
4
Pesticide resistant insect Survives longer Reproduces more Passes on more genes Pesticide resistance become more common NATURAL SELECTION = adaptation
5
If a few pesticide resistant insects survive, it will create a new generation of insects that carry the pesticide resistance gene
6
Why is it a problem? Insects that are pesticide resistant can eat all our crops!
7
What can we do? Farmers can use fewer pesticides Consumers can buy organic (without pesticides) when possible
8
Antibiotic Resistance
9
Antibiotics: Treatment to kill bacteria bacterial meningitis rash
10
Antibiotic resistance: Bacteria that do not respond to antibiotics Variation: some bacteria do not respond to antibiotics Selection: the resistant bacteria survive Inheritance: the resistant bacteria pass on their genes Time: over many generations the bacteria become resistant
11
If you get sick with a resistant bacteria, you can’t treat it with antibiotics Why is it a problem?
12
Doctors can prescribe fewer antibiotics Patients can finish ALL their antibiotics What can we do?
13
Tuberculosis
14
If a bacteria is resistant to the antibiotics, then it will survive and pass its resistance gene to the next generation
15
This is why doctors tell people to finish all their antibiotics! Otherwise a few bacteria may survive and pass on their resistance genes
