Based on similar appearance - traditional
Based on evolutionary relationships- modern
Known as cladistics- modern
Known as Linnaean classification- traditional
Linnaeus was a Swedish Botanist who was the first to classify organisms based on the structural similarities which organisms had. This method of classification came to be known as the Linnaean classification. Organisms which had more closer resemblances in structures and features had more groups or taxa in common.
The modern system of classification depends on the evolutionary history of organisms. It determines which organisms are more closely and have common ancestors in the past.

Determine whether each statement below describes traditional or modern classification.
Traditional Classification is based on similar appearance
Modern Classification is based on evolutionary relationships
Modern Classification is known as Cladistics
Traditional Classification is known as Linnaean classification
Which piece of information provided the stimulus for the shift from traditional classification to modern classification?
Answer: An understanding that species share a common ancestor
Fill in the blank below with the vocabulary word that best completes the sentence.
Using a ______ clock, scientists are able to estimate the amount of time that two species have been evolving independently.
How does the molecular clock work?
Answer: It compares the number of mutations that exist in the DNA of two different species.
Select the correct word from the drop-down menu to complete the sentences.
______ are branching diagrams that depict the evolutionary relationship among species.
_____ is a point in a cladogram where a single ancestral lineage breaks into two or more descendant lineages.
_____ is a group of organisms that includes an ancestor and all of its descendants.
_____ is any named group of organisms, whether they form a clade or not.
According to the cladogram, which of the following is the derived characteristic shared by amphibians and reptiles?
After much research and DNA analysis it has been determined that species in the same clade are actually more distantly related than originally thought. What is one way that the cladogram may change because of this information?
Answer: A node would be introduced
According to the cladogram, which species are MOST closely related?
Answer: D and E
Use the cladogram about fish to answer the following questions.
Which of the following best describes the organism located at point B?
Answer: Has jaw, but no bones
The organism at location D is the ______ to organisms at location A, B, and C.
According to the cladogram, arthropods are MOST closely related to which group of organisms?

How does natural selection change the frequency of genes or traits over many generations? Biology students conducted an experiment mimicking genetic variation and coloration. Students used different colored beans to represent animals that might be prey: mice, for example. A student in each group was the predator: a hawk. Beans (mice) were randomly scattered on multicolored floor tiles, each color within four tiles. The hawk collected mice (beans) for 10 seconds. Mice not eaten reproduced. Three generations of data a shown in the table. All BUT ONE could be a reason for the color variation in the mice. That is A) meiosis. B) mutations. C) genetic variation. D) asexual reproduction.
The answer would be D) asexual reproduction.
Asexual reproduction will produce a offspring that has the same genetic material with their parent. That mean the offspring will have the same genetic that code their parent color, thus their color is the same as their parent. Other option will allow the offspring to have different genes, so the offspring could have different color.
D. asexual reproduction.
Asexual reproduction results in genetic sameness, not genetic variation.
Which of the following is not a required process for the survival of animals? A. Elimination of waste B. Movement C. Response to stimuli D. Absorption of nutrients and oxygen
Movement is not a required process for the survival of animals.
This means that animals can survive without moving.
For example, during hibernation, a snake survives resting in a particular place without movement.
If a person's movement is confined to zero, the person can still survive, but if absorption of nutrients and oxygen stops, then the person shall die.
There are three major groups of mammals, categorized on the basis of their _____. see concept 34.6 ( page 739)
Why is ability to adjust conclusions were necessary important to critical thinking
