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
