T/F. The greek philosopher Aristotle grouped animals into land dwellers, water dwellers, and air dwellers.
T/F. To ensure accurate communication of information, biologists assign a unique two-word scientific name to each organism.
T/F. Linnaeus' system of classification was based on morphological characteristics. Modern biologists try to classify organisms based on their evolutionary relationships to other organisms, which may or may not be reflected in similar morphological characteristics.
T/F. Fossils are the most helpful form of evidence that can be used to construct a phylogenetic tree.
T/F. Cladograms represent direct information about ancestors and descendants, showing who came from whom.
T/F. Organisms in the Kingdom Animalia are multicellular and obtain nutrition by ingesting food.
T/F. The three-domain system of classification assumes that all living things had a common ancestor and that all living things today naturally fall into three groups that have descended from this common ancestor.
T/F. The three-domain system of classification has two domains of prokaryotic organisms, while the six-kingdom system of classification has onyl one kingdom of prokaryotic organisms.
T/F. The three-domain system of classification differs from the six-kingdom system in that it is based on a type of evidence that is found in all living things.
Taxonomy is defined as the science of
grouping organisms according to their characteristics and evolutionary history.
As we move through the biological hierarchy from the kingdom to species level, organisms
become more similar in appearance.
a mushroom is difficult to classify in Linnaeus' two-kingdom classification system because
it doesn't seem to fit into either category.
What was not a consideration for Carolus Linnaeus when he developed his system of nomenclature of organisms.
It should enable scientists to classify organisms according to their presumed evolutionary relationships to other organisms.
What scientist developed the system of classifying organisms by assigning them a genus and species name?
The correct order of the biological hierarchy from the kingdom to species.
Kingdom, phylum, class, order, family, genus, species.
The organism at the base of a phylogenetic tree is
the common ancestor of all the organisms depicted in the tree.
The DNA sequences of two species of sharks would
be more similar than the DNA sequences of a shark and a dolphin
If an early arthropod and early vertebrate embryo are split,
both halves of the arthropod embryo will die, while both halves of the vertebrate embryo will become whole, twin organisms.
