Example Informative Speech
An
example informative speech is often just the thing we need to get
ourselves going in writing our own informative speech.
So
here is the second one I have created. You'll want to check back
often as I'll be adding more samples to help inspire you in writing
your own!

See A Liger?
An
episode of the edgy, humorous, and often line-crossing show South
Park had the four young main animated characters singing the song
"Pig and elephant DNA just won't splice" after a visit
to the South Park Genetic Engineering Ranch. Unfortunately, this
is how much of the country thinks about hybrid animals.
When
most people hear the term "hybrid animal," they often
think of odd, mutant creatures - hippopotamuses mixed with lions,
dogs mixed with cats, or squirrels mixed with porcupines. Indeed,
the word hybrid invokes the imagination and encourages one to entertain
these improbable combinations as miracles of science.
However,
the phrase "hybrid animal" merely means a crossbreeding
of two animals - a process which has occurred for centuries, both
artificially and naturally.
The
idea of hybrids dates back to the mythology of ancient times. Folk
tales were full of animal-human hybrid stories like mermaids and
minotaurs. The word hybrid comes from the Ancient Greek, meaning
"son of outrageous conduct." But understanding hybrid
animals lies both in nature and science.
Hybridization
has been occurring in nature for thousands of years. Diaries of
early hunters in the northwestern territories tell of shooting bears
that were large and off-white with hairy paws, suggesting hybrids
of kodiak and polar bears. Recent DNA studies confirmed this is
possible.
The
mixing of animals that are closely related happens naturally more
than you might think. In fact, scientists have recently identified
a number of hybrid zones, or places where animal hybridization is
most likely to occur based on a number of different factors. These
hybrid animals are far more important to nature than you might think.
Evolutionary biology studies show that the fittest animals survive,
no matter whether they are hybrids or not, and while some are simply
not genetically compatible in terms of survival, many others are.
A
few examples of naturally occurring hybrid animals include the white
tail/mule deer, some Galapagos Finches, and the European Red Deer
and Chinese Sika Deer. Noted evolutionary expert Charles Darwin
even commented on animal hybridization. "Many species have
bred in various menageries . . . Strange as the fact may appear,
many animals . . . unite with distinct species and produce hybrids
quite as freely as, or even more freely than, with their own species."
Science,
as well as nature though, has created some of its own hybrids for
various purposes. Take, for instance, the mule - a cross between
a female horse and a male donkey, which has existed since Ancient
Roman times. For centuries, mules have been used as a means of transportation
and labor. Even today, their sure-footedness makes them one of the
best animals to have in rough terrain or narrow passages. In countries
such as Chile and China, mules are valued for their navigability.
In fact, mules are still used to tour the Grand Canyon's steep and
narrow trails!
Hybrid
animals are closer to home than even the mule, though. Common pets
like cats and dogs are often hybrid animals, having been crossbred
with another breed. Thoroughbred cats and dogs are valued for the
purity of their blood, but because of the cost involved with thoroughbreds,
most people find themselves with crossbred dogs or cats for pets.
The
value of hybrid dogs and cats is changing, though. Crossbred dogs
and cats were once considered mutts or mongrels, but today, with
the ever-increasing crossbreeding and technology, some find that
hybrid dogs and cats are "more valuable" because of their
temperate personality, the shininess of their hair, or other desirable
characteristics. Perhaps you want the security a Doberman Pinscher
can provide, but you do not want its aggressiveness. Breeding with
a more amiable dog could provide you with the best combination of
characteristics.
Crossbreeding
is a process that has occurred for centuries. There are many hybrid
animals in the world, whether produced artificially, by scientists
or naturally in a common habitat or because of familiar characteristics.
Though
many believe the unlikeliest hybrid animals, such as the liger,
can occur only in a laboratory, the hybrid polar/grizzly bear found
in the wild repudiates this belief. In this way, hybrid animals
provide us with fascinating questions on fertility as well as the
limits, or rather non-limits, of nature, while challenging our imaginations,
and our animated television shows like South Park to envision the
possibilities.
