Why Are
Animals So
WEIRD?
can be strange. Very strange. Many
animals seem bizarre to us. Giraffes have
long necks. Elephants have huge ears and
long trunks. Rhinoceroses have sharp horns.
And these animals arent even the strangest!
What makes some animals so weird? Its
all because of evolution . Creatures need
to adapt in order to survive. Some animals
live in harsh places such as the desert or
deep in the ocean. Over time, they must
evolve. They develop adaptations that
help them survive in this wild world. These
adaptations may seem weird to us, but these
animals couldnt live without them.
What adaptations help
animals survive?
How do extreme
environments cause
animals to evolve?
In what ways are humans
bizarre animals?
Baffling Bugs
have developed some creepy
features to help them survive
.
These critters
have lived on Earth for over million years
.
Scientists believe they were the first creatures
to live on land
.
And now they can be found
almost every place on Earth
.
Insects are a type of arthropod .
They are
invertebrates
.
They have an exoskeleton , a
segmented body, and jointed legs .
Everything
from a common brown spider to a crab is an
arthropod
.
This group of animals includes
some of the strangest species on Earth.
arthropod fossil
Grasshoppers use
their legs to hear!
Incredible Insects
Today, the Goliath beetle is one
of the largest insects on Earth.
Its about the size of a computer
mouse. And millions of years
ago, dragonflies nearly two feet
long flew through the sky!
Actual size!
Peppered Moth
Our world is always changing
.
And every
creature must adapt to survive.
Evolution occurs
when animals change over time and increase
their chances of survival.
The peppered moth
once spent its days resting on light-color trees .
Its black-and-white wings blended in perfectly .
But then the Industrial Revolution changed the
world
.
People began using more machines .
These
machines produced pollution that filled the air
.
The
light-colored trees became covered in dark soot .
The peppered moth needed to adapt to the new
environment
.
Some moths evolved darker wings
and bodies
.
The darker moths were better able to
hide from predators
.
In time, only black moths
This change didnt happen overnight .
It took more than years
.
But it allowed the
peppered moth to survive
.
Changing Colors
The peppered moth changed
from white to black through
years of evolution. The moths
that were best suited to the
new environment survived.
Flower Mantis
The praying mantis is one of the fiercest
predators on Earth. It waits to strike until its
