What type of rock are fossils most commonly preserved in
sedimentary
why did the population of peppered moths in England change from light to dark after the industrial revolution
Light moths were easy to see against sooty trees and were eaten
Which layer is the oldest
4
A characteristic that improves an individual's ability to survive and reproduce in a particular environment
Adaptation
identify ways that organisms can be compared to provide evidence of evolution from a common ancestor
All of the above
Why are advantageous traits more likely to be passed onto offspring?
Because they are more likely to survive and reproduce.
There are three species of birds on an island. Border A has a heavy bill for eating seeds. Bird B has a pointed bill for earing insects. Bird C has a sharp bill for eating both insects and seeds. If all insects on the island suddenly disappear, which bird or birds would be the least affected
Bird A
The above image shows four different finches that Charles Darwin found while on the galapa islands. This information led Darwin to develop his ideas for natural selection. According to darwin, what would be the most likey reason their beaks are different?
Both where they lived and what they ate were different
who deve the theory of evolution
Charles Darwin
A horse and a donkey can successfully mate to produce offspring known as a mule. Miles are sterile. Would mules be classified as a species
NOT*** Yes, the fact that have different number of ch makes them a different species or Yes the Mules have enough of their own traits to be considered a species/ no mules are to similar to the parent species
why is the mouse population changing over time
The hawks eat more light mice than dark mice because they can see the light mice more easily
According to the diagram, which fossil is the oldest
Trilobite
What is a species?
a group of organisms that can mate with each other and produce fertile offspring
Study of embryos of various organisms to show a common ancestor because of simularites in development. This is referred to as
embryology
In natural selection the selective agent is the
environment
A term that typically describes a species that no longer has any known living individuals
extinct
The preserved remains of traces of an organisms that lived in the past
fossil
The diagram shows fossils in different rock layers. Which of these statements about the age of these fossils is most likely correct
fossil d or older than c
The information provided by fossils about the earth's history
fossil record
Where would a scientist expect to find evidence of common ancestors and shared traits
fossil record
mutations are important because they bring about
genetic variation needed for a population to evolve
Some organisms that share a common ancestor have features that have different functions, but similar structures. These are known as
homologous structures
What is this an example of
homologous structures
What is true about scientific laws and theories
laws describe and theories explain
Which of the following are factors in natural selection
overproduction variation competition and selection
This family tree shows the relationship among certain primates based on the chemical composition of a protein and their blood. According to this tree, which pair is most closely related
owl monkeys and spider monkeys
The graph shows changes in two populations of herbivores in a grassy field. A possible reason for these changes is that
population B completed more successfully for food than population A did
Which term is term is used to describe the method in which scientists try to determine whether events or objects
relative dating
Which of the following is an example of a vestigial structure
the tailbone of a human
Genetic differences between organisms of the same species
variation
Two organisms that are closely rela would have
very similar DNA sequence
mutations are a change in what?
DNA
A fossil of an extinct dinosaur is found and the anatomy of the fossil shows simulaitires to that of a bird. What could this mean?
The extinct din and the modern bird share a common ancestor
Darwin found that finches in the Galapagos islands had different size and shape beaks. What is the advantage of having different shaped beaks?
To be able to eat the food readily available in the environment
which of the following is not an example of natural selection
breeding their cows to produce more milk
An original species from which all other related species evolved
common ancestor
What did Charles darwin observe in finch populations of the Galapagos islands
different species on different islands
The concept where the better adapted organisms survive to pass traits along to offspring
natural selection
Which process produced the two different types of beaks in the ground finch and the tree finch?
natural selection
process by which individuals that are better suited to their environment survive and reproduce most successfully; also called survival of the fittest
natural selection
