On a deep sea expedition, you capture a previously undiscovered sea creature that appears to represent a new phyla. It happens to have fertilized eggs that you get to spawn. You watch its development to determine which group of animals it might belong to. You see that the mouth develops first, and it goes through several larval stages in which it molts and regrows its skeleton.
Which big phylogenetic group of animals does this animal likely belong to?
A. Ecdysozoa
B. Lophotrochozoa
C. Diploblasts
D. Deuterostomes

- On a deep sea expedition, you capture a previously undiscovered sea creature that appears to represent a new phyla. It happens to have fertilized eggs that you get to spawn. You watch its development to determine which group of animals it might belong to. You see that the mouth develops first, and it goes through several larval stages in which it molts and regrows its skeleton. What other traits is it likely to have based on this type of development Radial symmetry Coelem Central Nervous System Two germ layers present yes or no for eacharrow_forwardYour age-dating put the age of the rocks you are examining in the early Devonian period. Because of this, you suspect that the vertebrate remains you found might belong to some of the earliest tetrapods (four-legged animals including land vertebrates) to walk the Earth. Examine the cladogram below. What is the sister group to the land vertebrates? Lampreys Sharks Lungfish Land vertebrates Tetrapoda Choanata Fingers and toes Osteichthyes Choanae Gnathostomata Bony ribs and shoulder girdie Vertobrata Jaws O Lampreys Vertebrae O Tetrapoda O Amphibians Lungfish Ray-finned fish Amphibiansarrow_forwardWhich of the following passages inaccurately describes the evolutionary process? Birds today are defined by the presence of feathers. Feathers have many uses to include thermoregulation, communication, sounds production, and of course, flight. Feathers seem to have evolved from reptilian scales, and likely originally evolved for the purpose of thermoregulation before flight. Mammals have three ossicles, or tiny bones, in their middle ear that aid the hearing: the malleus, the incus, and the stapes. The stapes is the oldest of the three bones, having evolved from the pharyngeal arch II, called the hyoid arch. We know it's the oldest as it is found in tetrapods (the columella) and in some more recently evolved fish. The malleus and incus evolved from bones of their ancestral mammal-like reptiles' jaws, the articular and the quadrate bone respectively. Those bones moved into the middle ear as the single dentary bone of mammals evolved. The acacia species Acacia hindsii, which is native to…arrow_forward
- The forelimbs of the organisms in Figure 1 are examples of what type of structures? What do these structures indicate about the evolution of the three organisms? What would be an example of a structure analogous to the last structure? How does the anatomy of the forelimbs show an evolutionary pattern?arrow_forwardWhat are examples of the following groups of vertebrates: Chondrichthyes, Actinopterygii, Actinistia, Dipnoi, and Tetrapoda? How many species are in each of the above groups? Which one has the most species? When did the first vertebrates appear, and when did they first live on land? Where do we find the earliest fossils of vertebrates, and where do we find the earliest fossils of terrestrial (land-living) vertebrates? What are the following and how are they related to humans: Pongo, Gorilla, Pan, Sahelanthropus, Ardipithecus, Australopithecus, Homo erectus, and Homo neanderthalensis? Which of these is our closest living relative? What are some of the traits that these organisms share with us? When and where did each of the extinct forms above live? What does this tell us about when our lineage split from the most recent ancestor we share with our closest living relative?arrow_forwardPart 3: Reconstructing evolutionary history Below is a phylogeny for six groups of placental mammals (Eutheria) from the Tree of Life website (http://tolweb.org/tree/) Artiodactyla (pigs, deer, cattle, goats) Cetacea (whales, dolphins, porpoises) Perissodactyla (horses, tapirs, rhinos) Hyracoidea (hyraxes, dassies) Sirenia (manatees, dugong, sea cows) Proboscidea (elephants, mammoths) Both the Cetacea and Sirenia are aquatic members of the Eutheria. All of their close relatives are terrestrial. We generally assume that the common ancestor of these groups was terrestrial (T) and that being aquatic (A) is a derived trait that evolved just twice (i.e. there were 2 independent changes from T→A). a) To the right of each taxon, write a T beside terrestrial taxa and an A beside aquatic taxa. I b) Now let's assume that the most recent common ancestor of this group was aquatic (A). What is the minimum number of changes (A→T and/or T→A) that could have resulted in the distribution of traits we…arrow_forward

- Pakicetus is an ancient wolf-like organism that lived 50 million year ago. It had wolf-like ears and nostrils on the front of its skull. Modem whales have a similar ear structure, but their nostrils are on the back of their skull. Aetiocetus lived 25 million years ago, had the same ear structure as both Pakicetus and modern whales, but nostrils in the middle of its skull. According to this information, the most likely concilusion that biologists could draw about the relationship of Aetiocetus to the other organisms is that Aetiocetus O evolved as whale ancestors lost their forward-placed nostrils through disuse. O is the ancestor of both Pakicetus and modern whales. O is not related to either Pakicetus or modern whales. O is a transitional form between Pakicetus and modern whales.arrow_forwardWhy did invertebrates evolve structures for protection? present scientific explanation please do not just copy from googlearrow_forwardPakicetus is an ancient wolf-like organism that lived 50 million year ago.
