Evolution
What is Evolution?
Change in a species biological characteristics over time (Through the generations)
What is Natural Selection?
An environmental factor favouring OR helping a certain biological characteristic in a species
Who is Charles Darwin?
The person who propsed the theory of Evolution
What is Artificial Selection?
A biological characteristic in a species favoured by humans and selectively bred
What are genes?
Genes are units of heredity
An individual organism changing as it grows is called ....?
An individual organism changing as it grows is called Maturation
4 Conditions for Natural selection
The 4 conditions for natural selection are:
1. Reproduction
2. Heredity
3. Variation in Fitness
4. Variation in Characteristics
What is Charles Darwin also known as?
Father of Evolution
1. Heredity
2. Variation in characteristics
Where are genes found?
Genes are found in the DNA
Evidence for Evolution?
Fossils and Anatomy are both evidence for evolution
What type of environment would cause convergent evolution to occur? (Don't be specific)
Similar environments would cause convergent evolution to occur
What century did Charles Darwin propose his theory of Evolution?
19th Century
Name 3 specfic things that have undergone artificial selection (Animal, Plants, Foods)
Dogs, Chickens, Corns, Watermelon, Banana, Cows, Pigs, Broccoli, Mustard
What are mutations?
Change OR Difference in the gene that causes it to be expressed differently
What is Divergent Evolution and what is Convergent Evolution?
1. Species sharing a common ancestor but evolving Different characteristics for Different functions
2. Species having different ancestors but develop similar characteristics with similar functions
Conditions of Natural Selection for Darwin's Finches
The conditions of natural selection for Darwin's finches are:
1. Able to reproduce
2. Beaks of finches were heritable
3. Finches with suitable beaks survived
4. Different beak shapes and sizes
Where did Charles Darwin go to observe the finches?
Galapagos Islands
Correct explanation = Full points
On the right Track = Half Points
Mutations of genes cause which condition in Natural Selection?
Mutations of genes causes variations in characteristics!
Did humans evolve from monkeys? Explain!
No, Humans evolved from a common ancestor of the monkey that shares biological characteristics that are similar to the monkey
What did Charles Darwin observe that helped him with his theory of Evolution?
Finches
What are the 2 conditions that are different from Natural Selection and why?
1. Reproduction - Humans take care of the reproduction by getting the organism to reproduce
2. Variation in Fitness - The organism doesn't need to worry about survival because humans will look after them and ensure they survive
