Evolution 1
The area where DNA is located in all eukaryotic cells.
What is the nucleus?
The ability of an individual to survive and reproduce is known as...
What is fitness?
The process in which a species has changed over time is known as...
What is evolution?
The principle that all species can be traced back to a common relative is known as...
What is common descent or ancestor?
This term refers to the availability of different traits and alleles within a population.
What is variation?
The shape of DNA. Spiral staircase is described as...
What is a Double Helix?
Any inherited physical/genetic trait that increases an organism's chance of survival is known as...
What is an adaptation?
A well supported testable explanation of phenomena that have occurred in the natural world is known as...
It not a law but...
What is a theory?
Finding fossils in different rock layers in the same place allows us to do this.
What is relative dating?
The concept of humans implementing plans for caring for a nonhuman population's habitat, care, and the prevention of extinciton.
What is conservation?
Instructions create different proteins which allow our cells to carry out a variety of functions needed to survive.
What are genes?
The concept that organisms who are the best suited to their environment will be the most successful in surviving.
What is survival of the fittest?
Preserved remains of ancient organisms, commonly in rock layers, used by Darwin to form his theory are known as...
What are fossils?
Speciation requires isolation.
The type of isolation where organisms are in different locations.
What is Geographic Isolation?
The concept that members of each species compete regularly for food, space, and other necessities is known as...
What is competition?
When an error occurs in the replication process it positively impacts the organism's ability to survive and reproduce.
What is a positive mutation?
The process in which nature/environment determines which individuals/adaptations survive is known as...
What is natural selection?
The shallowing of a gene pool due to fragmentation, not evolution
What is genetic drift?
What is The Galapagos Islands?
North American bear populations will bulk up eating fatty rich food sources before doing this. Bears will lower their activity outputs and sleep for the winter.
What is Hibernation?
When an error occurs in the replication process it negatively impacts the organism's ability to survive and reproduce.
What is a negative mutation?
Geologic or behavioral barriers lead to a new species forming over time.
What is speciation?
The geological time periods of Ice ages and warmer climates.
What is glacial and Interglacial periods?
Organs of many animals reduced in size so that they are merely traces of previously utilized organs are known as...
What are vestigial organs?
Structures between species that are different in structure but show signs of a common ancestry.
What are homologous structures?
When an error occurs in the replication process it does not impact the organism's ability to survive and reproduce.
What is a neutral mutation?
A non-native species that is introduced into to an environment and cause harm to the natural relationships that pre-existed.
What is an invasive species?
Different variations of the same gene in a population. Offspring can get two different from their parents.
What is an allele?
When 2 species similar in genetics, mate to form a new species.
What is hybridization?
When multiple species go extinct from within an environment.
What is mass extinction?
