Evidence of Evolution
Evolution

The process by which
life has changed over
time.
 Macroevolution
 Microevolution
Evolution
What are species?
 Species
literally means ‘kinds’.
 We recognize most species by their
appearance.
Evolution

Taxonomy( systematics) – branch  Will cover
of biology that names and
more in
classifies species
Unit 16
Carl Linnaeus
(1707–1778), a Swedish botanist, invented
the modern system of binomial
nomenclature.
Evolution

Example

Panthera pardus

Panthera pardus
Population

All the members of a
species living in a
particular area



new variations arise
these individuals tend
to survive
This is where evolution
occurs ( not indivual)
Adaptations

Adaptations are special features
that allow a plant or animal to live
in a particular place or habitat.

structures, physiology
Adaptations

Explain why life
is so diverse
Evolution
 While, evolution is
an explanation for the
unity of life.

All organisms share
the same
characteristics of life
because they can
trace ancestry to the
first cell or cells.
Evolution

Example:
Humans and monkeys share a common ancestor
which separated into 2 separate lineages
40 million years ago
New world South America migration
Old world
Today’s Lab

We will look at 2
types of data that
supports the
hypothesis of
common ancestors:

1) the fossil record

2) comparative anatomy
Don’t forget….quiz next week
