Evolution

Question 1

What is evolution?

Answer 1

Change in the genome/genetic sequence of a species over time

Question 2

What are the 3 main processes of evolution?

Answer 2

1. Variation within a species (no one is an identical clone to another person)
2. Reproduction (the rate at which a species reproduces determines how fast it evolves)
3. Selection (those best suited to their environment with be more successful as passing on genes)

Question 4

Evolution by natural selection?

Answer 4

Charles Darwin- those best suited to their environment, more successful at passing their traits onto the next generation

Question 5

Examples of constant environmental challenges?

Answer 5

• weather
• famine
• competition

Question 6

Battesian Mimicry

Answer 6

A harmless species resembles harmful species

Question 7

Mallerian species

Answer 7

Two harmful species look similar

Question 8

What is a mutation?

Answer 8

Permanent change for genetic material. It provides new alleles and a source of new genetic variation when inherited. Most are benign/harmful.
