The History of Evolution
A group of organisms that can breed and produce fertile offspring
Species
This is the process where organisms with favorable traits go on to survive and reproduce.
Natural selection
This means variation increases the chance of survival
Adaptation
This is an increase in random movement that lasts until a favorable environment is reached.
Kinesis
These are similar body structures that have different functions.
Homologous structures
This is the type of breeding that includes two different species producing offspring that are usually sterile.
Interspecies breeding
What kind of animal did Charles "Daddy" Darwin study on the Galapagos Islands?
Finches
What are the two main causes of genetic variation?
- Mutations
- Recombination
This is the movement in a specific direction either toward or away from a stimulus.
Taxis
These are organs or structures which have lost most or all their original function.
Vestigial structures
This was the scientist who came up with the theory of natural selection
Jean Baptiste de Lamarck
Who theorized natural selection?
Charles Darwin
Inherited traits that help an organism survive and reproduce in a given environment regarding behavior, response, or action
Behavioral adaptation
The movement of a plant in response to an environmental stimulus.
Tropism
Structures that have similar functions, but different structures
Analogous structures
The _____ a fossil in the ground, the older it is.
Deeper
This is a type of information that has the potential to make an organism change its behavior in an environment
Stimulus
Inherited traits that involve the physical structure or anatomy of an organism
Physical adaptation
Measure of the ability to survive & produce more offspring
Fitness
This is the collection of every known or discovered fossil.
Fossil Record
This was the scientist who came up with the theory of acquired inheritance.
Jean Baptiste de Lamarck
These are Inherited traits that make an individual different from others.
Variation
Inherited traits that involve the internal functions or chemistry of an organism
Physiological adaptation
Humans select traits thought to be advantageous.
Artificial selection
This is a way to determine the age of fossils by comparing the ratio of carbon to nitrogen.
