Revision Evolution MC Answer 8
Stramatolites, and acinent cyanobacteria that have surivited inte Shark Bay in Western Australia, are very similar to those found as fossil remains dateing back millions of years. Why have thes ancient forms remained unchanged for so long?
a)The stromatolites are able to adapt to any environment
This untrue as any environment would mean air and land, also to survive they have to outcompete other organisms that have access to the same resources.
b)The environment has not changed significantly over time.
This is the best answer, it means that if the enviroment has not changed, the organism has not had to change
c) the stromatolites have not been able to undergo mutations
Mutations and sex drives variation. This organism may have created many new species, just the one most similar to the ancient one is living in the similar organism
d) the stramatolites are not able to adapt to a changing environment
This is would explain why they are not wide spread, but it does not explain why they have survived for millions (billions of years)
This video suggests that they are in all environments as something else, and when the enviroment is right they get going.

Revision Evolution MC Answer 6
This is from 2007 Year 10 midyear
Natural Selecion is a mechanism used by Charles Darwin to desceribe Evolution: this has sometimes been referred to as "survival of the fittest". What does the term refer to?
a) the fittest is the best camouflaged
Camouflage means colour or shape that make it hard for a preditor or potential prey (in the case of a tiger) to distinguish the animal from the surroundings.
b) the fittest can survivre anywhere
This means live in all places, air, water, soil tropics, beaches, suburbia.
c) the fittest produces the most offspring
If these offspring then live to reproductive ages, then this would mean that they would dominate. Producing offspring, comes at a cost to the mother. If a cat has 20 kittens a litter, and 17 die, it is not as well off a cat that produce 5 viable kittens.
d) the fittest is the most adaptable to its surrounding
This generally means that the organism has more possiblity and capablity of producing offspring that are themselves able to flourish and reproduce.

About Me
- drhill
- I come from a Science family: My father Geoffrey Hill was Australia's first computer programmer on CSIRAC the fourth computer in the world. He is credited with invention of Computer music and the development of “Interprogram” a language before Basic. My PhD is in Atomic and Molecular Physics. I have researched the activated oxygen layer above the ozone layer, and 'Assigned' the world's smallest molecule. At the University of Toronto I researched high power UV lasers. I have specialized in automation in fibre optics. This developed into research in Machine Intellect and Robots. I have enjoyed work as an Explainer with Questacon and my time as a part-time soldier. I currently teach High School Science at Epping Boys’ High.
