Evolution and Classification

Which of the following are the domains of life?

Bacteria Archaea Eukaryota

The formal system of naming species, first developed by Linnaeus, is called ____ nomenclature.

Binomial

____ nomenclature refers to Linnaeus' method of naming species using a unique two-word name made up of the genus and species names.

Binomial

________ nomenclature gives each species a unique, two-word name.

Binomial

Which of the following groups contain only eukaryotic organisms?

Protista

T or F Charles Darwin developed the theory of evolution by natural selection.

T

T or F Evidence of evolutionary relationships can be found in the fossil record.

T

T or F Evolution occurs through the passing of advantageous traits from parent to offspring.

T

T or F Humans share a common ancestor with chimpanzees

T

T or F In natural selection, adaptations are passed down from parents to their offspring.

T

T or F Life on Earth has been evolving since it began.

T

T or F The change in the characteristics of living things over time is called evolution

T

T or F The evolutionary process occurs in organisms through changes in traits that are passed down from one generation to the next.

T

All modern classification systems have their roots in the Linnaean classification system.

TRUE

The Eukaryota domain includes the Animalia (animals), Plantae (plants), Fungi and Protista (protists) kingdoms.

TRUE

____ is the science of classifying organisms.

Taxomony

Define taxon and give an example.

Taxon are hierarchies of organisms from least exclusive to most exclusive. The least exclusive for example is Kingdom, then Phylum, Class, Order, Family, Genus and Species(being the most exclusive includes organisms that can reproduce and produce fertile offspring)

What is taxonomy?

The science of classifying organisms

How was the Linnaean system revised since Linnaeus created it?

The taxon 'domain' was added

Briefly, explain the theory of evolution.

The theory of evolution presented by Darwin was that species that are better adapted to an environment will be able to produce more offspring than those that are not well adapted to the environment. Darwin gave this process the name of natural selection and it is how evolution or changes occur over many genearations

What is a domain? What are the three domains of life on Earth?

This phylogenetic tree is based on comparisons of ribosomal RNA base sequences among living organisms. The tree divides all organisms into three domains: Bacteria, Archaea, and Eukarya. Humans and other animals belong to the Eukarya domain. From this tree, organisms that make up the domain Eukarya appear to have shared a more recent common ancestor with Archaea than Bacteria.

theory of evolution by natural selection, origin of the species

What does the term Homo sapiens mean?

wise human

For how long have humans been trying to classify the diversity of life?

2,000 years

Arrange the order of taxa in Linnaean taxonomy from most to least inclusive. 1. Order 2. Genus 3. Phylum 4. Class 5. Species 6. Kingdom 7. Family

6, 3, 4, 1, 7, 2, 5

There are _____ taxa in the original Linnean classification system.

7

Which of the following is not a taxon?

Aves

A ______ is a taxon in the modern revised Linnaean system that is larger and more inclusive than the kingdom.

Domain

Which domain includes Plantae, Fungi, Animalia, and Protista?

Eukarya

What term refers to the change in the characteristics of living things over time?

Evolution

Homo sapiens literally means "ordinary human."

FALSE

The Linnaean system of classification consists of a hierarchy of groupings called genuses.

FALSE

The science of classifying organisms is called genetics.

FALSE

The species is the largest and most inclusive grouping in the Linnaean classification system.

FALSE

The taxonomic category "family" falls between kingdom and class. T or F

FALSE

The three domains of life on Earth are Bacteria, Archaea, and Prokaryota.

FALSE

Characteristics of organisms are passed from one generation to the next through their ____________________.

GENES

Which of the following best exemplifies binomial nomenclature?

Genus species

Binomial nomenclature means:

Giving each species a name that includes two words - one that is more general and one that is more specific

What is natural selection?

In natural selection, some members of a species, being better adapted or suited to their environment, produce more offspring than others, so they pass "advantageous traits" to their offspring. Over many generations, this can lead to major changes in the characteristics of the species. Survival of the Fittest! (Darwin)

This is the highest taxon in Linnaean taxonomy.

Kingdom

What is the largest and most inclusive group, according to Linnaeus' classification system?

Kingdom

Which one of the following represents a correct hierarchy?

Kingdom, phylum, class, order, family, genus, species.

What is the PROCESS by which populations of organisms change over time

Natural Selection

Evolution occurs by a process called?

Natural selection

Polar bears and brown bears share a common ancestor. Which process led to the evolution of polar bears and brown bears from a common ancestor?

Natural selection

Some members of a species that are better adapted to their environment can produce more offspring and pass "advantageous traits" to their offspring. Evolution occurs through this process, and this process is called

Natural selection

Which process explains how some members of a species pass on advantageous traits because they are better suited or adapted to their environment?

Natural selection

Create a taxonomy, modeled on the Linnaean classification system, for a set of common objects, such as motor vehicles, tools, or office supplies. Identify the groupings that correspond to the different taxa in the Linnaean system.

On homework CK12

Name of book Darwin wrote on evolution

Origin of Species(stated theory of natural selection)

The full classification of human beings is as follows: Animalia, Chordata, Mammalia, Primates, Hominidae, Homo, Homo Sapiens. Based on the above information, what is the name of the order to which humans belong?

Primates

What is evolution?

a change in the characteristics in species over time

Binomial nomenclature refers to the method of naming species with two names, consisting of the _____ name and _____ name

genus, species

What is binomial nomenclature? Why is it important?

gives each species a unique, two-word Latin name consisting of the genus name and the species name. having two names uniquely identifies a species.

A domain is a taxon _______ than the kingdom.

higher
