Evolution.. (3 answers)
Is a gradual process of change
Is a gradual change in the gene pool of a population
Can be divided into 3 categories
Is an abrupt process of change
Is an abrupt change in the gene pool of a population
Can be divided into 4 categories
These 3 things happen in evolution:
Genes mutate
Individuals are selected
Chaos occurs
Populations evolve
People fail to adapt
Mutations dissolve
• Microevolution: ❌ • Macroevolution: ❌ • ❌ is cumulative ❌
The types of evolution are
Convergent
Divergent
Co-evolution
Advergent
Provergent
Dis-evolution
Animals look similar but are not related in
Divergent evolution
Convergent evolution
The process by which two or more species become more and more dissimilar is
Dis-Evolution
Match the co-evolution examples Predator & ❌ Bats & ❌ Bees & ❌ Lemming & ❌ Wolf & ❌
All of these are evidence of evolution EXCEPT (check all that apply)
Fossil
Footage
Biochemistry
Migration patterns
Homologies
Adaptations
Vestigial structures
Comparative embryology
Species today
Diets
Structures that are similar in their fundamental layout & construction and suggest a common ancestry are
Homologous
Analogous
Vestigial
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...
Mutation
Environment
Natural selection
Extinction
Genetic drift
Recombination
Gene flow
Alleles
Dietary patterns
Movement
Mutations occur by chance
Rate of mutation can be influenced by environment
Mutations help decrease genetic variation
The three types of mutations are..
Point mutation
Frame shift mutation
Random mutation
Loose mutation
Active mutation
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 fittest smartest modest oldest( fittest, smartest, modest, oldest )
Natural selection decreases ❌ and increases ❌
The examples of natural selection are
Pesticide resistance
Darwin's finches
Antibiotic resistance
artificial selection
sickle cell anemia
Peppered moths
cancer cells
Mutations
Genetic variation
Types of selection ❌ - optimum for most average trait ❌ - extreme forms of the trait are selected for ❌ - extremes in traits have greater fitness ❌ - dimorphism attraction
❌ is... Transfer of genes from different populations Movement of individuals from one population to another. ❌ is... Allele frequencies in a population change as a result of random events Related to small populations
Movement in: ❌ (increasing variation) Movement out: ❌ (decreasing variation)
An evolutionary event in which a significant % of the species or populations is killed and causes a loss in genetic variation is
Bottleneck effect
Founders effect
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: ❌ ❌ ❌ ❌ ❌ ❌ ❌
Hardy-Weinberg ❌ due to: Mutation Gene Flow Genetic Drift Non-random mating Natural Selection
Hardy-Weinberg Equilibrium ❌ due to: Large population Random mating No mutation No migration No natural selection
For evolution to occur, gene frequencies must . (lowercase)
