# data[].attributes.body
Homology is the study of structural or development similarity based on descent from common ancestors. e.g mammals and amphibians have 4 legs.

Justify or refute this statement: ‘Australians have a responsibility to conserve their unique species’.

I do believe we must protect our rare species because they aren't found anywhere else in the world, they are only found here.

Compare and contrast absolute and relative dating of fossils.

# data[].attributes.body
Absolute dating is the measure of decay, while relative is the process of determining the order of past events

Should we use genetic technology to bring back extinct species? Discuss your point of view.

Should we use genetic technology to bring back extinct species? Discuss your point of view.

# data[].attributes.body
I believe that we should but we shouldn't start with massive organisms like dinosaurs, we should start small then progress further.

They are rare due to the fact that they decompose quicker than harder organisms.

# data[].attributes.body
It means for a species to have sexual selection throughout an evolution.

What were some advantages/ What is Sexual Selection

# data[].attributes.body
1 advantage was sexual selection, this helps a species ward of diseases and avoid extinction

What disadvantage of sexual reproduction was cited by the scientists

Sexual reproduction isn't as efficient of creating more offspring than an asexual reproduction,

How much variation would you expect to see in a species where a large number of offsprings are produced by asexual reproduction 

# data[].attributes.subject
How much variation would you expect to see in a species where a large number of offsprings are produced by asexual reproduction 

# data[].attributes.body
The variation in an asexual offspring reproduction would be very limited.

Why do Australian animals differ to African animals

# data[].attributes.subject
Why do Australian animals differ to African animals

# data[].attributes.body
They differ because Australia has a wide variety of biomes whereas Africa only has a select few. This means that different species will have adapted differently to our climate

# data[].attributes.body
No evolution will keep happening in order for us to adapt to our different environments.

Why have some species gone extinct and some have not

# data[].attributes.subject
Why have some species gone extinct and some have not

# data[].attributes.body
Some species adapted to their ever changed environment, their food chain position changed around because of different variables,

# data[].attributes.body
The process of an organism adapting to become stronger and a better version of itself e.g fish evolving and adapting to what they are today.

What do fossils have to do with evolution

# data[].attributes.body
To show where organisms have lived. They also show how organisms have changed over time. They show the progression of organisms over time. They are pieces of evidence that determines the development of characteristics, age of fossils and preserve traits
