Define the three domains of life.
A hierarchy is a system of organization that involves successive archaeon.
The domain Eukarya used to have four kingdoms called nested groups within a hierarchy.
Protists do not constitute a separate kingdom but acteristics, which is why researchers later fly are classified as animals.
leopards and lions are placed together in a very broad collection of species.
Taxonomists now place into a group with a smaller number of species called felines.
Felidae are predatory cats.
A group of protists are found in the species that are placed together into small groups.
In this section, we and Animalia will consider how biologists use a hierarchy to group similar species.
Kingdom Plantae is part of the Land Plants and Relatives group.
Taxonomy places species into hierar chical groups.
Millions of different species can be found in the three domains of the king of life system.
They were divided into doms Monera, Protista, Fungi, Plantae, and Animalia.
Smaller groups make it easier for biologists to appreciate the relationships among many species.
The organisms are grouped into three groups.
There are seven super groups.
The seven super groups encompass most of the eukaryotes.
There are several small eukaryotic lineages that are classified outside of the seven supergroups.
There are fewer species that are similar to each other.
The gray wolf is classified in the data.
At some point in their development, no mon features.
There are three notochords, gill slits or arches.
Milk is produced by the mammary glands and the ature.
The gray wolf exceptions exist in the 26 orders of mammals.
Operons can be found in some organisms, such as the worm Caenorhabditis elegans.
Taxonomy aims to relate the diversity of species to their evolutionary relationships.
As new species are discovered and some become extinct, the numbers in this figure will change.
