### alteration:

Variation
* Many variations do exist with the animals colour or size.
* Most variation affects gene expression
  - influences life
* Some variations allow members of a species to survive and reproduce better than others
  - are forms of food, such as potatoes and asparagus
* affects availability
  - behavior
  - capacity
  - male mate strategies
  - outcomes
  - photosynthetic responses
  - ranges
  - values
  - water availability
* also ensures more bones are exposed to forces and hence adapt with new bone growth
  - occur in the development of the odontoid process
  - term used in biodiversity for the variety of life forms in a given ecosystem
* always exists in living populations, and it results in differences of fitness.
* are important in the survival of a species.
* are the differences in characters among individuals of a species
  - materials upon which the other factors, or causes, of evolu- tion work
* arises primarily through random mutations and recombination.
* can have environmental or genetic causes
  - occur at the whole organism- and suborganismal level
  - only affect future generations if it is inherited
* cans have dramatic effects
  - significant effects
* caused by the surroundings is called environmental variation.
* causes major problems
  - potential
* comes from reproduction.
* continues throughout the human lifespan as people age at different rates.
* contributes to biodiversity
  - the process of evolution
* creates problems.
* depends on functional interaction
  - geographic locations
* describes how one quantity varies or changes as another quantity varies or changes.
* determines effectiveness
  - the variation of the direction of the particles
* digital library of information for the study of music.
* exist in temperature over time from site to site.
* exists among individuals in a species
  - within all populations of organisms
* has advantage
  - big impact
  - components
  - direct impact
  - input
  - large impact
  - no effect on an individual's ability to survive and reproduce
* helps evolution
  - species survive, and it's the reason species change over time
* impacts success.
* involves meiosis.
* is activities
  - also essential for selection and breeding to meet present and future human needs
* is an important key to understanding how and why zebra stripes evolved
  - at the core of evolution and selection
* is caused by loss of genes
  - mutation and maintained by selection
  - common to all plants whether they reproduce asex- ually or sexually
  - created by random mutations
  - due to a combination of genetic and environmental factors
  - essential for natural selection and therefore for evolution
  - important for the continued survival of a species in changing environments
  - most important to the breeder and the organism
  - necessary for the survival of a species
  - perturbation
  - processes
  - random fluctuations and miscellaneous changes inherent in every part of every process
* is the angle between a magnetic and geographic meridian
  - difference between magnetic north and true north at a given location
  - differences between individuals of the same species
  - error in the compass caused by the Earth's magnetism
  - fundamental concept underlying statistics
* is the key to genetic progress
  - raw material which allows populations to change over time
  - result of sexual reproduction and mutation
  - root cause of poor quality in product and process
  - themes
  - therefore one of the cornerstones of genetics
  - useful for the survival of species over time
* leads to heterogeneity
  - speciation The evolution of different species from a single ancestor
* measure of media noise and other micromagnetic characteristics.
* occur because people kill out of a combination of complex social factors and pathology
  - in response to seasonal changes in hemispheric temperature differences
  - over a wide range of time scales, from hours to the age of the Earth
* occurs at levels
  - during periods
* occurs in growth
  - shapes
  - shell shapes
  - winter
  - within habitats
* produces diversity.
* provides information.
* relates to ages.
* results in continue evolution
* rule of all life - plant, animal and man.
* universal fact about all species.

  * Some variations change the way the cells look or where they are put.
+ Evolution, Darwin's theory, Variation, Inherited variation: History of science
  * Variation can only affect future generations if it is inherited. Because of the work of Gregor Mendel, we know that much variation is inherited. Mendel's 'factors' are now called genes. Research has shown that 'almost every individual in a sexually reproducing species is genetically unique'.Futuyma D.J. 2005. 'Evolution'. Sinauer, Sunderland, Massachusetts.
+ Infantilism
  * Infantilism or diaper fetishes are different in self image and the focus of attention. Both ideals can be found in the same person at the same time and are similar. However, it must be said that 'both have nothing to do with' having a sexual preference for children, or pedophilia. In any case, there is no single form, but a variety of infantilism types. Some infantilists are not obvious and try to blend in, while others wish they could be free of all guilt and responsibilities. All variations focus on diapers and babyhood.
+ Shirred eggs, Variations: Egg dishes
  * Variations involve replacing the butter with various types of cream. Provence and Normandy have their own versions.
