2. Teritary
The different beaks and seeds represent ________________
Variation

Lower layers
If a species cant adapt to a changing environment this occurs
Extinction
2 causes of variations
Sexual Reproduction
Meiosis
Mutations

Name 2 species that would NOT compete for food and explain why
Random Answers
You have samples of a population where 49% of the population have 5 fingers , a recessive condition.
What is the freequency of p?
.3 or 30%
How does Speciation occur?
(1 species into 2 species)
They must separate and for millions of years and not be able to interbreed
Each population will have their own random mutations
Populations must be isolated for long periods of time without gene exchange
