AS/A2 Evolution
Learning Objectives
After attending this session, students will be able to:
▪ Define a species
▪ Give 2 prominent names related to evolution
▪ Give an example of allopatric speciation
▪ Give an example of sympatric speciation
▪ Give examples of how natural selection can effect changes in a
population
▪ Explain the relevance of evolution or genetics to a modern zoo
Lesson Plan
This session is based on a PowerPoint presentation.
▪ Introduction
Definition of evolution.
Concept of a species.
A Brief history of evolution (Lamarck and Darwin).
▪ Main lesson
Darwin’s theory of Natural Selection.
The importance of variation.
Speciation (allopatric and sympatric using examples of Zoo species
where possible).
Selection (directional, disruptive and stabilising again using examples
of Zoo species where possible.
▪ Plenary
Recap of concepts covered .
The relevance of the concept of species, selection and evolution to
work at Chester Zoo.

Species discussed during session
A huge variety of animals and plants are discussed during this
session of these the species that can be seen at the Zoo include
Giraffe, orang-utan, elephants, cichlids, Ring-tailed Lemur, Okapi,
zebra, rhino and orchids.
Species to visit before session (or after session if at 10.30)
Ideally visit species that will be discussed during the session
Elephants – To the left of the Main Entrance
Zebra – past Monkeys
Rhino – To the right of the Main Entrance
Ring-tailed Lemur – On Lemur Island opposite the chimps. (these
can be hard to spot, other lemurs, Gentle Grey, Black and White
Ruffed and Red Ruffed can be seen opposite the camels, Onagers
and lechwe)
Giraffe – Opposite the Tropical Realm
Okapi – Past the giraffe, over the bridge and on the right
Orang-utans – Opposite the Chimps
Cichlids – In the Aquarium opposite the orang-utans
Orchids – In the Grow Zone next to the Ark Restaurant

Suggested activities to link with session
Before visit
Some background knowledge of the above concepts would be
useful. Pre-visit knowledge of some of the animals would also be
desirable (but by no means essential) to maximise students learning
opportunities on the day.
During visit
Living fossils – We have a number of species that are considered living
fossils including Tuatara (in the Tropical Realm), Monkey puzzle tree
(Andean Garden – By the condors and coatis) and Ginko (at the
back of the Tropical Realm, near to the Hyacinth Macaws). Why have
these species remained unchanged?
Visit primates (Monkeys, Miniature Monkeys, lemurs, capuchins (back
of the Tropical Realm)) and apes (Chimps and orang-utans) and
consider the evolution of humans.
Visit Europe on the Edge – Between penguins and tigers. The birds in
this enclosure show a variety of beak types think about how these
might have evolved.
Visit the ruffed lemurs opposite camels and Onager. The Black and
White and Red Ruffed Lemurs are sufficiently different from each other
to be classified as subspecies. They may become new species in time.
Look at the ID signs and suggest how speciation may be occurring in
these Lemurs. Think about how it could be established if they were
different species.

Aquarium
During visit continued…
While visiting species around the Zoo look for conservation signs
and the threats to these species. Could the threats have
consequences on evolution? E.g. habitat destruction isolation
populations, hunting reducing numbers and variation.
After visit
Plan a breeding programme for a species, consider variation, subspecies etc.

Things to arrange prior to visit
Please check details on confirmation letter, any queries please call
01244 650205.
Arrange a pre-visit to the Zoo, contact us 01244 650205 for details.
Arrange appropriate number of group leaders and collate contact
details.
Assign students to a group leader, ensure students and leaders know
the running plan for the day, have staff contact details and map of
the Zoo (click here).
Ensure group leaders have a plan for the day including; student
names, time and location of teaching session (e.g. a copy of the
confirmation letter) and where to meet, if necessary, after the session
as well as a map of the Zoo.
Running plan for the day
•Time and location of teaching session
•Time and location to meet for teaching session
•Time and location to meet for lunch
•Time to visit Twilight Zone (all students under 16 must be
accompanied through the Twilight Zone)
•Time for students to visit the gift shop (the shop at the entrance is
open all year round, opening times of the other 2 shops vary
throughout the year) All students under 16 should be
accompanied in the gift shops
•Time and location to meet when leaving the Zoo

The day of your trip: arriving at the Zoo
Please help us to make your entrance to the Zoo as smooth as possible
Allow plenty of time to get to and into the Zoo, it can take over 30
minutes to enter the Zoo and reach the Education Centre, particularly
at busy times of year.
On arrival the group leader only should approach the main gate with
the confirmation letter. Students and other staff should remain on the
coach.
This provides an ideal opportunity for another member of staff to run
through itinerary for the day with students and helpers, to hand out
work sheets, information, maps, talk times etc.
Once the paperwork has been completed the group leader can
collect the group from the coach to be counted into the Zoo by Gate
Staff.
There are toilets at the main entrance both inside and outside the Zoo.
Rainy day – indoor enclosures
The Aquarium, Tropical Realm, Twilight Zone, Spirit of the Jaguar, Islands
in Danger are all undercover, indoor exhibits.
Additionally, macaws, Chimps, orang-utans, giraffes, elephants, rhinos,
Monkeys , Miniature Monkeys all have undercover viewing.

Your teaching session
Sessions are run in 3 classrooms all located in the Education Centre
next to the Spirit of the Jaguar exhibit.
Please be aware that it can take 30+ minutes to cross the zoo
particularly at busy times of year.
On arrival at the Education Centre please wait outside the
appropriate room (Cook, Columbus or Cousteau), as stated on your
booking confirmation, for an Education Officer to greet you.
Please don’t block doorways to education classrooms as there may
be classes about to leave.
Each teaching session will last approximately 50 minutes.
There is plenty of open space for lunches outside the Education
Centre. On rainy days there is an indoor picnic area (Arara Picnic
Lodge) past the Spirit of the Jaguar exhibit.
There are toilets opposite the Spirit of the Jaguar house just past the
Education Centre.
If you are delayed for any reason and may be late for your
teaching session please contact 01244 650205, we may be
able to help!
