Task2: Diagnostic
Read the information below and then spend 10 minutes revising specialised
cells and the definition of adaptation from workpack 3 before spending 10
minutes completing task 2 -the diagnostic. Once completed mark your

L10 – Scientific Reading
Complete this reading below, using the glossary when needed, using this
information and your own knowledge to complete task 1.
A pre-recorded reading of the information has also been included in the slides.
Word Definition
Prehistoric A time in the past before history was recorded
Egyptian Pharaohs
An ancient Egyptian King
Ancestor A living thing from which one is descended. Example: I am an ancestor of my great great grandfather
Carcasses The dead body of an animal
Immune system A system in a living organism that protect the living thing from diseases
Herbivores An animal that eats only herbs and grasses – an animal that does not eat meat
Darwin v Doudna: Who was the greatest scientist?
Darwin In 1831, aged 22, Charles Darwin set off on a five-year voyage around the world. He was fascinated by the variety and distribution of wildlife and fossils he discovered. After much thought, Darwin devised the theory of natural selection to explain his observations. The theory proposes that:
• Individuals of a species that are best adapted to their environment survive. This is the survival of the fittest.
• The survivors reproduce and pass on their favourable characteristics to their offspring. This is natural selection.
• Over many generations, natural selection results in new species.
Doudna Jennifer Doudna was born in 1964. She worked with others to create a gene-editing technique called CRISPR. CRISPR allows scientists to cut genes out of DNA molecules, or even to add new ones. The technique could enable scientists to control the future of evolution.
Should extinct species be brought back to life? Over the last 500 years, human actions have caused the extinction of over 800 species. Extinct species include the Dodo, Tasmanian Tiger, woolly mammoth and Quagga. Extinct species can now be bought back to life if their DNA is preserved. In theory we could give dinosaurs and dodos a second chance. But should we? The giant creatures of the prehistoric world, such as the dinosaurs, saber-toothed tigers and woolly mammoths, continue to intrigue our imaginations. However, some of these creatures were not as ancient as we think them to be. Though no man ever saw a living dinosaur during his lifetime, the woolly mammoths, for instance, did in fact roam the face of the Earth even as the Egyptian pharaohs were busy building the pyramids of Giza, and for some time thereafter. What Were Woolly Mammoths?
The woolly mammoths are the ancestors of Asian elephants. The discoveries of frozen carcasses and body parts of these elephant-like creatures in Siberia and Alaska, as well as the depiction of these animals in ancient cave paintings, have allowed scientists to extensively study the appearance and behaviour of these giants. These mammoths were roughly the size of present day African elephants, and were well adapted to living in the Ice Age conditions of their time. They had two layers of fur cover and short ears and tails to remain protected against frostbite. They were also herbivores like the present day elephants, and lived on a diet of grasses and hedges.
When Did They Become Extinct?
The mammoths completely disappeared 4,000 years ago from the Wrangel Island, several centuries after the constructions of the pyramids at Giza. Scientists believe that the woolly mammoths were killed due to the warming up of the environment and due to humans moving into their habitats, killing the creatures for their meat and using their bones and tusks to make human dwellings, tools, and artwork.
But How Does It Work?
Every single living thing is made of DNA. DNA is the building block of life, the code — essentially — that all carbon-based lifeforms read in order to function. From the 20th century onward, humans have been able to not only read and see the code of life but change it and edit it to our liking. This process, although once expensive became much more exciting with the development of CRISPR-Cas-9.
CRISPR-Cas9 is developed from the DNA editing immune system in bacteria. You
see, when bacteria get infected by viruses (yes they do get sick 😷), they capture
snippets of DNA from the invading virus, known as CRISPR arrays. If the virus attacks again, the bacteria “remembers it”, and can then cut the DNA of the virus apart, killing the virus. Scientists can reprogram the CRISPR-Cas9 system in bacteria. They can then edit or change the DNA of species to whatever they want to.
Now — let’s say you — for whatever reason, wanted to revive an extinct species. To do that, you would first have to collect the extinct species’ DNA from bone/fossil samples and then you would have to find a living relative and insert the extinct DNA into it. Which is exactly what scientists have been trying to do. George Church, a geneticist at Harvard Medical School, plans to insert the mammoth DNA extracted from ancient bones into the Asian elephant.
Task 1: Respond to the following question by writing a letter to the scientists.
Question: Should we bring extinct species back from the dead? Your task is to write a letter to the Scientists
currently trying to insert the ancient DNA of
Woolly Mammoths found in bones into Asian
Elephants to bring back the Woolly Mammoth.
In your letter you are to explain your reasons
for or against the research. You should
include some information from this article to
support your points, showing that you
understand what a woolly mammoth is and
you should include some points of your own
based on what you have learned in this topic
so far on the potential dangers of introducing
a new species to an environment.
• Think about the cost of this research - Should we be spending money on
protecting and helping endangered species instead.
• Think about the ecosystems that already exist. Could this Woolly Mammoth
be a new predator? What does it eat?
• Think about what could happen if we took this technology too far. What if
scientists wanted to start changing human DNA.
Sentence Starter:
Dear Scientists,
I am currently a student at Ark Globe Academy where I have just learned about
evolution and natural selection. I have just read an article on your plans to bring back
Woolly Mammoths from extinction. I think that this is a good/bad idea because….
