Evolution.. (3 answers)

These 3 things happen in evolution:

• Microevolution: [blank_start]change within a species[blank_end] • Macroevolution: [blank_start]large changes creating a new species[blank_end] • [blank_start]Macroevolution[blank_end] is cumulative [blank_start]microevolution[blank_end]

The types of evolution are

Animals look similar but are not related in

The process by which two or more species become more and more dissimilar is

Match the co-evolution examples Predator & [blank_start]prey[blank_end] Bats & [blank_start]flower[blank_end] Bees & [blank_start]plants[blank_end] Lemming & [blank_start]wolf[blank_end] Wolf & [blank_start]moose[blank_end]

All of these are evidence of evolution EXCEPT (check all that apply)

Structures that are similar in their fundamental layout & construction and suggest a common ancestry are

Structures similar in appearance and function, but from different origins are

Structures that are no longer useful but are presumed to have been necessary in ancestral species are

The agents of change are...

Mutations occur by chance

Rate of mutation can be influenced by environment

Mutations help decrease genetic variation

The three types of mutations are..

Variation is not inheritable

Offspring tend to resemble their parents

Variations can increase chance of survival

All organisms are prone to reproduce equally

Survival of the [blank_start]fittest[blank_end]

Natural selection decreases [blank_start]genetic variation[blank_end] and increases [blank_start]speciation[blank_end]

The examples of natural selection are

Types of selection [blank_start]Stabilizing[blank_end] - optimum for most average trait [blank_start]Directional[blank_end] - extreme forms of the trait are selected for [blank_start]Disruptive[blank_end] - extremes in traits have greater fitness [blank_start]Sexual[blank_end] - dimorphism attraction

[blank_start]Genetic Flow[blank_end] is... Transfer of genes from different populations Movement of individuals from one population to another. [blank_start]Genetic Drift[blank_end] is... Allele frequencies in a population change as a result of random events Related to small populations

Movement in: [blank_start]Immigration[blank_end] (increasing variation) Movement out: [blank_start]emigration[blank_end] (decreasing variation)

An evolutionary event in which a significant % of the species or populations is killed and causes a loss in genetic variation is

When a small population leaves a larger one and causes allele from small groups to begin to diversify from the large group is

Order of Taxonomy: [blank_start]Kingdom[blank_end] [blank_start]Phylum[blank_end] [blank_start]Class[blank_end] [blank_start]Order[blank_end] [blank_start]Family[blank_end] [blank_start]Genus[blank_end] [blank_start]Species[blank_end]

Hardy-Weinberg [blank_start]FAILS[blank_end] due to: Mutation Gene Flow Genetic Drift Non-random mating Natural Selection Hardy-Weinberg Equilibrium [blank_start]WORKS[blank_end] due to: Large population Random mating No mutation No migration No natural selection

For evolution to occur, gene frequencies must [blank_start]change[blank_end]. (lowercase)
