hypothesized that geological force has shaped earth slowly

Analogous Structures Have

Different Internal Traits, Similar external traits

Breaking Hardy-Weinberg's Principles means

organism behavior has no effect on heritable characteristics

Inherited characteristics that improve fitness

Artificial Selection is

Questions 41

Answers

1
Total set of genes in a population
Genetic Drift
Gene Pool
Mutation
Gene Flow
2
Small changes to the gene pool over time is called?
Population Change
Genetic Drift
Gene Flow
Mutation
3
How did Charles Lyell expand Hutton's work?
both answer 1 and 3
processes that were slow/fast shape the earth in amazing way
earth is 1000 years old
processes occuring now is the same that shaped ancient earth
4
The bottleneck effect
Greatly reduces the gene pool
Greatly reduces genetic variation
Greatly increases genetic variation
Will always leave the gene pool untouched
5
A random change in allele (genetic) frequency is called
Genetic Drift
Gene Pool
Mutation
Gene Flow
6
What did James Hutton contribute to Darwin's Theory?
Use and Disuse of Traits
hypothesized that geological force has shaped earth slowly
geological force has not shaped the earth
geological force affected population growth
7
How did Malthus contribute to Darwin's Theory?
Populations have a limit
change over time
Earth is millions of years old
how the earth is being shaped by geological processes
8
Analogous Structures Have
Similar Internal Traits
Different Internal Traits
Similar external traits
Different External Traits
9
Breaking Hardy-Weinberg's Principles means
The starting phases of evolution
Often times death
A reduction of population
A lowered gene pool
10
Lamarck's hypothesis?
all species are the same
humans have changed over time
certain traits from other animals could not be passed on
organisms were adapted to their environments
11
Example: Organisms with an average body size are the most fit
Directional Selection
Isolation Selection
Disruptive Selection
Stabilizing Selection
12
What was Hardy-Weinberg's Principle?
Unless equilibrium is broken, evolution does not occur
when allele frequencies in population are different
used to describe evolving population
how natural selection occurs in organisms
13
Microevolution is NOT caused by
Non-Random Mating
Natural Selection
Mutation
Fossil Records
14
Two populations have different mating schedules
Geographic Isolation
Evolutionary Isolation
Behavioural Isoluation
Temporal Isolation
15
Which did Darwin do?
Species evolve based on what they use or don't use
Observed population growth in England
Realized living things have been evolving over time
Discovered geological processes
16
When individuals atthe upper and lower ends of the curve have higher fitness
Directional Selection
Disruptive Selection
Isolation Selection
Stabilizing Selection
17
Microevolution is NOT caused by
Gene Pools
Genetic Drift
Gene Flow
Mutation
18
Polygenic Traits are
All traits
Traits controlled by many genes
Traits controlled by many different people
Traits controlled by 1 gene
19
Species descending with change over time is?
Founder's Effect
Natural Selection
Descent with Modification
Hardy-Weinberg's Principle
20
Which is NOT an assumption of Hardy-Weinberg?
NO migration
Small Population Sizes
No mutations
Random Mating
21
When individuals nearthe center of the curve have higher fitness
Stabilizing Selection
Disruptive Selection
Directional Selection
Isolation Selection
22
Homologous Structures
Two species having the same body parts (Ex. Wings)
Similar Structures that show similar ancestories
Similar embryos between species
Similar biochemistry between species
23
Bottleneck effect is
Organisms that move to other islands
The dramatic reduction of a population
Speciation due to mutation
The stretching of an organisms neck
24
What is evolution?
Evolution is how living organisms have developed over time
evolution is the passing of genes
evolution is any change over time
evolution is species that are the same
25
What was NOT one of Darwin's conclusions?
Species vary over time
Species vary globally, locally and over time
Species are the same in areas with the same climates
species vary locally
26
Which is NOT a form of evidence for evolution?
Diversity of Life
Fossil Records
Homologous Structures
Embrotic Similarities
27
Different Mating rituals Leads to?
Evolutionary Isolation
Geographic Isolation
Behavioural Isoluation
Temporal Isolation
28
Adaptation that constantly pushes a population in one direction
Isolation Selection
Stabilizing Selection
Directional Selection
Disruptive Selection
29
Which is NOT an assumption of Hardy-Weinberg?
Artificial Selection
No mutations
No Natural Selection
Large Populations
30
Fitness means
Intelligence
Ability to reproduce
How long something can live
Strength
31
What did Lamarck not seem to understand about his hypothesis of evolution?
how are traits different from each species
organism behavior has no effect on heritable characteristics
how artificial selection worked
how animals adapt to their environment in different ways
32
Adaptations
Inherited characteristics that improve fitness
Are the same as mutations
Are the changes we see between two people
One's fitness
33
