Biology Fun Fact: While other primates are furry, human skin is exposed to the elements. It’s not that we’re ‘naked’ – our hair is just really short over much of our bodies. In the warm places where our ancestors lived, evaporation of sweat from skin was a great benefit in cooling our bodies. Our brain runs so ‘hot’ that sweating & cooling proved vital for evolving our big brain.
Unit Learning Goal: Students will understand the scientific principles & processes involved in biological evolution.

Organizing LifeSPECIES:
a group of organisms that can breed & produce fertile offspring
QUESTION: Can 2
different species mate &
produce an offspring?
Pg. 35 – “Evolution & Origin of Life notes”
THIS IS A LIGERTHIS IS A
MULE
Offspring of a male donkey & female horseOffspring of a male lion & female tiger
The Liger… Male lion & female tiger
Like most hybrids they are sterile
However, an occasional female has been found which can reproduce. No fertile males have been found.
POPULATION:a group of organisms of the same species who live
in the same area at the same time.

Biology Fun Fact:The platypus is a creature with amazing features which are seen in diverse species: mammals (mammary glands, 3 ear bones, tail & fur), reptiles (egg laying, poison & spurs for defense), birds (bill, webbed feet) & fish (electro receptor in bill which allows to catch prey under water with eyes closed, has large vocal range). The platypus is designed for feeding & swimming in water, but lives on land in burrows it digs with its claws & can feed on insects & other land creatures.

TYPES OF ADAPTATIONS• Structural• Physiological• Behavioral
Let’s look at each type as we consider 2 species: the tundra & icecap-dwelling arctic fox & the desert dwelling fennec fox.
Pg. 37 – “Evolution & Origin of Life notes”
arctic fox (Alopex lagopus) fennec fox (Vulpes zerda)
Structural Adaptation: physical appearance of an organism
EX: Big ears & small ears of foxes.
• Large ears allow heat to escape easily from the blood vessels near the
surface – cooler blood keeps fennec fox from overheating
• Small ears prevent arctic fox from losing heat
Pg. 37 – “Evolution & Origin of Life notes”
QUESTION:
An arctic fox can weigh as much as 8kg. A fennec fox weighs at most 1.5kg.
Make a claim for how this difference in mass is a structural adaptation to the
foxes’ respective environments.
ANSWER:
The large size of the arctic fox allows it to retain more heat than the smaller fennec
fox.
Physiological Adaptation: related to biochemical
processes at work within an organism’s body
Compare the processing of food & water:Arctic fox: food is scarce in winter; effective at storing food energy as fat.Fennec fox: little free water available; adapted to get all moisture it needs from fruits, roots, & leaves.
Pg. 37 – “Evolution & Origin of Life notes”
Behavioral Adaptation: innate (inherited) actions that individuals of a species do
Arctic fox:
Can be active any time of the day; ready to find food whenever available.
Fennec fox:
Is nocturnal; sleeps during the day & hunts at night
Pg. 37 – “Evolution & Origin of Life notes”
QUESTION:
A fennec fox raised in captivity away from other fennecs will try to dig a burrow in
its cage. Explain why burrow-digging is an innate behavior, not a learned
behavior.ANSWER:
The behavior is instinctive because the fennec fox did not have to be taught the
behavior by another fennec fox.
Adaptations Work Together
Adaptations work together to produce a specific fit for surviving in a particular environment.
Example of fennec fox: The big ears (structural) cool fox & gives acute hearing which helps when fox hunts at night (behavioral) & the fox has special retina (physiological) that gives the fox night vision.
Pg. 37 – “Evolution & Origin of Life notes”
Let’s connect…Where did you see Structural, Behavioral or Physiological adaptations in the organisms you studied?

Biology Fun Fact:The Red Queen hypothesis (law of constant extinction) suggests that an evolutionary advance by one species represents a deterioration of the environment for all remaining species. The other have to “keep up with the times or they will die off!
Unit Learning Goal: Students will understand the scientific principles & processes involved in biological evolution.

When looking at several adaptations over time, a species
is seen to
EVOLVE!!!!!!!!!!
Pg. 40 – “Evolution & Origin of Life notes”
EVOLUTIONGenetic change in a species over time
How does this happen?The following scientists came up with possible hypotheses:
• Jean Baptiste de Lamarck• Charles Darwin • Alfred Russell Wallace
Pg. 40 – “Evolution & Origin of Life notes”
Jean Baptiste de Lamarck1744-1829First to hypothesize about species modification
His hypothesis was that evolution occurred by inheritance of “acquired traits”
Not determined by genes
Individuals acquire characteristics during their lifetime & pass them on to their offspring
Example: giraffes acquire long necks by stretching them to reach leaves
Pg. 40 – “Evolution & Origin of Life notes”
Lamarck’s Hypothesis
Darwin agreed with Lamarck about species modification but disagreed with how it occurred.
Hypothesis: selection acts on a variation already present
Darwin believed giraffes had various sizes of necks & the environment selected the characteristic that was best suited (beneficial) Giraffes with longer necks were the ones that
survived & passed on their genes Variation (neck size) happens through
random mutation, not created by experience
CHARLES DARWIN 1809-1882
Pg. 40 – “Evolution & Origin of Life notes”
Darwin’s hypothesis became known as: Evolution by Natural
Selection
Pg. 40 – “Evolution & Origin of Life notes”
HOW DID DARWIN COME UP WITH HIS
HYPOTHESIS???
