Vocab/Terms
A TRAIT that helps an animal survive long enough to reproduce.
Adaptation
How do adaptations ARISE (come to be) in a population?
Mutations - individuals that are born slightly different
Beetles
Color-based camouflage survival from predators
Bacterial Infections
How could penicillin and other medication ULTIMATELY contribute to creating a population of "super bacteria" that cannot be killed with medicine?
A group of individuals that live in the same area (a herd of antelope in a valley)
Population
Why are differences or adaptations within a population helpful?
If there were no differences, there would be no adaptations. There would never be an advantage.
Finches
In the Galapagos islands, there is different food types on different islands. How might this affect the shape of those birds beaks?
Antibiotics
Why is it important to take ALL the dosage of antibiotics prescribed by a doctor?
Every individual in a population is SLIGHTLY different. Some of those differences are good (ADAPTATION)
Individuals within a Population
Which members of a population are most likely to survive?
The ones that are best suited for survival. They may not be the "fittest", but they are the most likely to "win" at getting food and not dying.
Tortoises
How could the shape of their shell affect their ability to reach certain food sources?
Antibiotics pt 2
What is the relationship between the MORE TIMES a medicine has been prescribed and HOW EFFECTIVE it is on bacteria in general?
Organisms that are BETTER at getting food, surviving, or reproducing will LIVE longer than others. They battle for resources.
Competition
Why is "Survival of the Fittest" slightly inaccurate?
Sometimes, being the biggest or strongest isn't really an advantage. Also, some sicknesses come with their own plus sides (sickle cell anemia)
Moths
How could the color of moths on polluted and clean buildings affect their survival?
When one organism eats another. This is a pressure for natural selection, meaning, if you don't get eaten, you must have a good adaptation compared to others.
Predation
Why are humans almost unaffected by natural selection?
We can change our environment AND we take great care in helping the weak or those that can't care for themselves.
Mosquitos, Malaria, and Native Africans
How might Sickle Cell Anemia, a painful disease, actually be a benefit to native Africans. How does natural selection play into this?
