Heredity; Life Goes On

All living things inherit a set of characteristics or traits from their parents.
Members of any given species transfer traits from one generation to the next.
The passing of traits from one parent to offspring is called heredity and causes the offspring to resemble the parent.
Heredity applies to all organisms including humans, animals, plants, insects and even bacteria.
A trait is a Characteristic the determines how an organism looks, acts or functions.
Dogs will always have puppies, just as cats will always have kittens and acorns will always grow into oak trees.
Variations are differences of an inherited trait among the members of a group.
The difference in paw size, tail length or hair coloring are examples of variations.
However, for some organisms living in the wild, color can make a big difference of survival.
For example, a moth with brightly colored orange and yellow wings will not survive very long if its environment is the dark bark of a pine tree.
The brightly colored moth can easily be be seen and eaten by birds.
The environment, the surroundings in which the organism lives is constantly changing.
Sometimes the changes are gradual, as in climate changes.
Other changes may be sudden, such as volcanoes, earthquakes, floods, landslides or violent storms.
When an environment changes some organisiams die, or move to a new environment.
As a result the population changes.
Some behaviors, the way in which an organism responds or acts, are inherited from the parent organism.
If an adult dog barks at passing cars, so might a puppy that grows observing the parent.
Calves follow their mothers to the water toughs, and soon learn to go there by themselves when they are thirsty.
Instincts, behaviors that are inherited from the parent organism, explain... shy salmon migrate upstream to spawn;a cat purrs, a duck swims, a spider spins a web and termites eat wood.
Learned behaviors are those actions and behaviors that ate learned through trial and error or brought about by the environment.
Dogs learn different ways to let their owners know when they want to go outside of go inside the house.
A snowshoe rabbit with large feet to help them travel over snowy terrains/or a crane has long legs enabling it to walk and stand in muddy ponds/and a hawk which has a hooked beak for ripping and tearing prey those are examples of specialized structures of body parts of different animals.
