What distinguishes animal from fungal Heterotrophy is that only animals?
Both animals and fungi are heterotrophic. What distinguishes animal heterotrophy from fungal heterotrophy is that only animals derive their nutrition by… ingesting it. What is most consistent with the hypothesis that the Cambrian explosion was caused by the rise of predator-prey relationships?
For example the presence of mammary glands is a synapomorphy for mammals in relation to tetrapods but is a symplesiomorphy for mammals in relation to one another—rodents and primates for example.
What are the synapomorphies that define mammals?
An example of an apomorphy or synapomorphy is the presence of derived traits such as an erect gait fur and mammary glands in mammals but not in other vertebrate animals like amphibians and reptiles which have retained their ancestral traits of a sprawling gait and a lack of fur.
Are homologous traits synapomorphies?
Synapomorphies are homologous traits but not all homologous traits are synapomorphies. Comprised of an ancestor and all of its descendants. A group composed of a collection of organisms including the most recent common ancestor of all those organisms and all the descendants of that most recent common ancestor.
What traits do all animal phyla have in common?
…
Phylum Vertebrata
- Notochord.
- Dorsal Nerve Cord.
- Post-anal tail.
- Pharyngeal slits.
What do all animals have in common they all contain?
All animals are eukaryotic multicellular organisms and most animals have complex tissue structure with differentiated and specialized tissue. Animals are heterotrophs they must consume living or dead organisms since they cannot synthesize their own food and can be carnivores herbivores omnivores or parasites.
What are the four characteristics common to most animal?
- The levels of organization.
- Nature of coelom.
- The presence or absence of segmentation and notochord.
- Organization of the organ system.
Which of the following animals does not have a body cavity?
Is radial or bilateral symmetry better for swimming?
Radial symmetry is more advantageous for active swimming than is bilateral symmetry. … Bilaterally symmetric animals can be streamlined for swimming but radially symmetric animals cannot. d.) Radial symmetry occurs most frequently in animals that catch their prey by rapid swimming.
What is the most ancient branch point in animal phylogeny?
the most ancient branch point in animal phylogeny is that between having. radial or bilateral symmetry.
What is one characteristic that separates deuterostomes from all other animals?
Like echinoderms chordates are deuterostomes. The four most prominent characteristics that distinguish chordates from species in all other phyla are the presence of a post-anal tail a notochord a dorsal hollow nerve cord and pharyngeal slits (also called gill slits).
Which of the following characteristics is shared by a hagfish and a lamprey? A new species of aquatic chordate is discovered that closely resembles an ancient form. It has the following characteristics: external armor of bony plates no paired lateral fins and a suspension-feeding mode of nutrition.
Why do mammals and birds eat more often than reptiles?
Mammals and birds require much more food and energy than do cold-blooded animals of the same weight. This is because in warm-blooded animals the heat they lose is proportional to the surface area of their bodies while the heat they produce is proportional to their mass.
Which of the following animal group is entirely aquatic?
cetacean (order Cetacea) any member of an entirely aquatic group of mammals commonly known as whales dolphins and porpoises.
Which is not a characteristic of all animals?
The option that is not a characteristic of animals is D) have cell walls. Animal cells do not have cell walls which distinguishes them from other…
What is the key difference between a Coelom and Pseudocoelom?
What is the key difference between a coelom and a pseudocoelom? A coelom is a true body cavity whereas a pseudocoelom is a false coelom that is not fully functional. Only a coelom is fully lined with mesoderm tissue. Pseudocoeloms arose early in animal evolution and evolved into coeloms.
What is a Synapomorphy for the apes?
Synapomorphy—a trait inherited by members of two or more grades from their common ancestor wherein the trait was an apomorphy for example bipedalism in the various grades within our tribe Hominini.
How can a trait be both Synapomorphy and Symplesiomorphy?
Synapomorphy is a common property that is demonstrated by two or more groups of organisms that can be utilized as a property to trace and detect the most recent ancestor from whom they (both groups of organisms) descended while symplesiomorphy refers to an ancestral character or a trait that is shared by one two or …
- a tail posterior to the anus.
- dorsal hollow nerve cord.
- muscles arranged in bundles (sarcomeres)
- cartilaginous dorsal notochord.
What is Apomorphy in taxonomy?
Why are synapomorphies important?
How are synapomorphies and Plesiomorphies different?
As nouns the difference between plesiomorphy and synapomorphy. is that plesiomorphy is (cladistics) a character state that is present in both outgroups and in the ancestors while synapomorphy is (cladistics) a derived trait that is shared by two or more taxa of shared ancestry.
What do homologous and analogous structures have in common?
Homologous structures share a similar embryonic origin analogous organs have a similar function. For example the bones in the front flipper of a whale are homologous to the bones in the human arm. … The wings of a butterfly and the wings of a bird are analogous but not homologous.
Are bat and bird forelimbs homologous?
Interestingly though bird and bat wings are analogous as wings as forelimbs they are homologous. Birds and bats did not inherit wings from a common ancestor with wings but they did inherit forelimbs from a common ancestor with forelimbs.
Is every homologous trait and synapomorphy?
All homologues are synapomorphics but not vice-versa. Absence of an anatomical element for instance can be a taxonomical synapomorphy but not a homology because homologues are positive anatomical parts. Hence synapomorphy and homology should not be considered as synonymous.
What traits do all animal phyla have in common quizlet?
- Level Of Organization: cells tissues organs.
- Symmetry: bilateral.
- Cephalization: present.
- Coelom: present.
- Appendages: present.

Phylum Nematoda includes the round worms which have a complete digestive system a new feature in animal evolution meaning they have separate holes for the mouth and anus.
What are the major characteristics of this phylum?
| Phylum | Meaning | Distinguishing characteristic |
|---|---|---|
| Chaetognatha | Longhair jaw | Chitinous spines either side of head fins |
| Chordata | With a cord | Hollow dorsal nerve cord notochord pharyngeal slits endostyle post-anal tail |
| Cnidaria | Stinging nettle | Nematocysts (stinging cells) |
| Ctenophora | Comb bearer | Eight “comb rows” of fused cilia |
