Genes vs Environment
Two factors that can affect how an organism grows
What are genes and the environment?
A change in a person's DNA.
What is Mutation?
Gray squirrels eat white oak acorns right away. Do they help white oaks reproduce? (Yes or No and Why)
No, because the seeds are eaten and therefore will affect the White Oaks ability to reproduce.
Preserved remains or traces of past life
What are Fossils?
Structures that are similar because of shared ancestry
What is Homologous?
What would change if you take a fish out of lake in Louisiana and put it in a lake in Michigan?
The environment change, change in climate, change in food source, change in predators, can affect the survivability of the fish.
If many organisms with a certain trait survive and reproduce, that trait will:
What is become more common in the population?
Name one condition that would help a forgotten acorn become a new tree.
What is: enough water, sunlight, soil nutrients, and space (any one)?
Fossils found closer to Earth’s surface are usually:
What is Younger?
Bird wings and insect wings are examples of this:
What are Analogous Structures?
Information that determines eye color, hair type, and blood type
What are Genes?
Mutations occur when there is a change in this...
What is DNA?
When one organism eats another
What is a Predator?
Similar bone structures in different species suggest:
What is a shared ancestor?
Embryos of different vertebrates often look most similar ____ in development.
What is Early?
Two people eat the same foods but grow to different heights because of:
What are genes?
A mutation that affects reproductive success will MOST directly impact the:
What is the population?
The ability of an organism to reproduce by itself.
Asexual reproduction
Different Structure, but the Same Function
What are Analogous Structures?
Similarities in early embryo development provide evidence of common ____.
The process where helpful traits increase in a population over time
What is natural selection?
All mutations are bad (True or False and why?)
False because it could lead to new favorable traits and variations that could aid in that species survival.
Evidence for evolution based on similarities in embryos
What is Embryology?
A Human's leg, Whale's Flipper, and a Bat's wing are all examples of this:
What are Homologous Structures?
Similar structures in related organisms might have ___ functions.
