What term explains how
populations change over time?
Biological Evolution
What is the term for a change in
behavior or physical trait that
helps an organism survive in its
environment?
Adaptation
A group of organisms that can
mate with each other and produce
fertile offspring is called a_____?
Species
What do you call a group of
individuals of the same species?
Population
Organisms with traits best suited
to their environment are more
likely to survive. This is
called________ ________?
Natural Selection
He’s called the father of
evolution and came up with
the theory of natural
selection. Who is he?
Charles Darwin
What is the name of the group of
islands Darwin sailed to on his
quest to study nature?
Galapagos Islands
Charles Darwin sailed around the
earth for five years on a ship
called?
HMS Beagle
Charles Darwin did not
understand the role _________
played in evolution when he was
developing his theory?
Genetics
Darwin’s theory of natural
selection had 4 elements. They
are (1)________, (2)_______
______, (3)______ __ _______,
and (4)_______ ________?
(1) Overproduction
(2) Inherited Variation
(3) Struggle to Survive
(4) Successful Reproduction
_______ are trace remains of
an organism that lived long
ago, most commonly
preserved in sedimentary
rock?
Fossils
What are two things scientists
can look at when comparing
species to see if they share a
common ancestor?
(1) Similar DNA
(2) Similar Traits
A ______ can be passed
from parent to offspring
through genes?
Trait
Organisms that sexually
reproduce do not have identical
offspring. The fact that their
offspring is not identical is
known as ________ variation?
Inherited Variation
A ________ can be a source of
new traits in an organism?
Mutation
Speciation is the formation of
new species as a result of
evolution. What are the 3 steps in
this process?
(1) Separation
(2) Adaptation
(3) Division
A historical sequence of life
indicated by fossils found in
layers of the Earth’s crust?
Fossil Record
____________ ______ is the
period between the birth of one
generation and the birth of the
next generation. Insects have a
very short one?
Generation Time
How something lives, eats, and
survives in its ecosystem?
Niche
________ is the difference in
structure or character from others
of the same species or group?
Variation
What did Charles Darwin conclude
about the finches he studied on
different Galapagos Islands?
The shape and size of the beaks
evolved over generations depending
on their diet.
Darwin’s theory of natural
selection was influenced by
Malthus’s study on population.
What did this study state about
the relationship between food and
population growth?
Food supplies cannot support
unlimited population growth
Bacteria and insects have adapted
to become resistant to antibiotics
and pesticides. How is this quick
adaptation possible?
Bacteria and insects have a short
generation time.
In every population and species there
are 4 limiting factors. They are:
(1)_________, (2)_________,
(3)_________, and (4)_________.
(1) Starvation
(2) Disease
(3) Competition
(4) Predation
Scientists are observing the
genetic makeup of two organisms
by looking at their DNA. The
DNA is very similar. What might
they conclude about these
organisms?
They may share a common
ancestor.
