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