1. “A bunch of prehistoric
penguins stopped using their
wings to fly and the wings
shrank from disuse. These
penguins with shrunken wings
passed their shrunken wings
characteristic to their
offspring.”
3. “Conditions like antibiotics in
the environment will affect
which bacteria of today
survive to produce more
complex or more simple
bacteria of tomorrow.”
2. “There were many
prehistoric penguins with a
variety of characteristics.
The penguins with wings
suitable to swimming must
have had an advantage and
produced more offspring than
others.”
4. “The simple bacteria of
today will have complex protist
and fungi descendants in a
number of years.”
5. “A species of cichlid carries its babies around in its
mouth because members of that species developed
the characteristic in response to an environment with
few good nesting spots.”
7. “Anteaters developed long thin tongues because they
are perfect tools to scoop ants out of very small
cracks or holes in logs or mounds. Over time, this
complex feature developed as anteaters tried to
become better and better at catching their food.”
6. “A species of
cichlid carries its
babies around in its
mouth because
when cichlids
entered this
environment, there
were many
different types of
cichlids. The cichlids
who carried their babies in their mouths had an
advantage over cichlids who didn’t, because there were
very few good nesting spots..”
9. “Cacti have many adaptations to allow them to live in
the desert. Many years ago, there were plants with
many different types of walls and
surfaces and those that had
features suitable for living in the
desert survived and passed on
their characteristics to their
offspring.”
10. ”Cacti have many adaptations
to allow them to live in the desert.
Cacti grew spines and developed
thick walls to keep in water
because they needed those to live in
the dry climate.”

8. “The ancestor of today’s anteaters lived among many
creatures who ate ants, but the ancestor, through
random variation, had a longer tongue and was able to
more easily catch ants. It thrived, produced more
offspring, and outcompeted the others with shorter
tongues.”
11. “Long ago, individual fish living in the deep ocean grew
lights on their heads because lights were needed to see
in the dark depths of the ocean where they live. They
passed on the ability to grow lights to their offspring.”
12. “Long ago, there
were many
different fish, some
with bioluminescent
lights on their heads
and some without,
who migrated to
the depths of the
ocean. The fish with bioluminescent lights were better
able to attract food and thrived, becoming the
ancestors of lantern fish we have today.”
