Evidence for Evolution
Give an example of empirical evidence
geographic time, fossils, embryonic, developmental, genetic, etc.
Is natural selection micro or macro evolution
microevolution
The scientist that also discovered the theory of natural selection but lost all of his evidence in a shipwreck was?
Alfred Wallace
What is the difference between renewable and nonrenewable resources
renewable resources are replenished just as fast as they are used (water, air, solar) nonrenewable are dwindling and do not replenish.
What is evolution?
theory that all life on earth came form one common ancestor.
Give an example of a vestigial structure of a human
What determines fitness of an organism
Ability to survive and reproduce
Overhunting is an example of what type of gene flow
Bottleneck effect
What is an invasive species
a non-native species that out competes species that live there originally. Can lead to extinction
How do we define a species?
If they can have fertile offspring together
What element do we use for radiometric dating in Biology?
Carbon
What 3 things are needed for natural selection to occur
Selection, different reproductive success, and variation of traits
Why is genetic equilibrium so hard to achieve
It is hard to see a species without mutations, or selective breeding
What is the difference between gradual and mass extinction
Mass is sudden & catastrophic. Gradual happens over year, population slowly dwindles
Why is evolution considered a scientific theory?
It cannot be witnessed in real time, even though there is a lot of evidence to back it.
What are trace fossils
Fossils not a part of a living thing, but rather give insight to their behaviors (footprints, etc.)
All organisms that are born cannot survive, what process does this describe?
Selection
Fireflies use specific flashing patterns to attract a mate. If a male flashes the wrong pattern, they may not be able to find a mate. What type of reproduction is this?
Behavioral
what is the difference between endangered and threatened
Threatened- low population could face extinction in future
Endangered- faces extinction in all parts of its range
What is the difference between a positive and negative feedback loop?
Positive amplifies the loop
Negative counter acts or reduces
Cacti are CAM plants meaning they do photosynthesis at night to reduce water loss. This makes them better fit for their environment. Being a CAM plant is an example of
An adaptation
How are adaptations, natural selection and evolution all connected?
Adaptations lead to high fitness, natural selection weeds out those with low fitness, over time, evolution will show those with high fitness populate more
Rabbits leaving their population and joining a new one is an example of?
Gene flow
Name 1 impact humans have on the environment & a solution
TBD (teacher will determine)
What is the difference between relative and absolute dating?
Relative refers to eras or descriptions of time (older/younger) absolute is numerical and definintive (100 years)
