Is it too much to ask to construct a phylo tree?

Part 6: Complete the chart below. Place an "X" in the appropriate column to indicate which mystery fossils have the traits listed. Note: A trait may be found in more than one mystery fossil. Mystery Fossil A Mystery Fossil B Mystery Fossil C Large Cranial Capacity Name: Kate McNamee. Austra/Homo Worksheet Orthognathic (Flat) Face Low Cranium 2. Based on this information, which mystery fossils do you think belong to the genus Homo? 3. Based on this information, which mystery fossil do you think is an australopithecine?

Plsss help

Let’s see what you already know! For this activity, you are a palaeobiologist interested in reconstructing ancient ecosystems. You have searched the scientific literature and found 5 clues:1. The majority of the field site (~100 km2) is mostly covered with limestone. However, in one area younger mudstone rocks are preserved above the limestone.2. The limestone has many invertebrate fossils including starfish, sea urchins, and coral, but mostly has bivalve shells. 3. The limestone also has vertebrate fossils. Small shark teeth are sometimes found. A single elasmosaurid plesiosaur tooth was discovered. Amazingly, several coprolites (fossilised dung) have fish vertebrae found in them; one coprolite even has a feather inside!4. The mudstone is rich in tiny ‘microfossils’ that include:• Small mammalian teeth • Pollen from 29 different families of flowering plants: the most common families are Caesalpiniaceae (peacock flowers)5. The mudstone also has larger fossils, including:• Pelvic and…

Earth is about 4.5 billion years old. In order to characterize the events that happened in this very long time scale, scientists have developed the geologic time scale. Here, the age of Earth is divided into (1), which in turn divided into (2), and are further subdivided into (3). The geologic time scale is so-called since the different subdivisions are based on the fossil record.

5.) in the space below, draw an evolutionarily accurate phylogenetic tree with the 5 lineages of amniotes shown in the top figure, but with a different arrangement. ( exclude lungfish and amphibians)

Scientists on a fossil expedition in the Florida Everglades excavated an area with four strata (layers). Z Hawthorn Group Y Tamiami Formation X Undifferentiated sediments W Miami Limestone The Everglades W X Z They found vertebrate fossils in all four strata: 124 fossils in the Miami Limestone, 75 fossils in the Undifferentiated sediments, 138 fossils in the Tamiami Formation, and 62 fossils in the Hawthorn Group. The scientists concluded that the Hawthorn Group contained the oldest fossils. Is this a valid conclusion? Yes. The Hawthorn Group must contain the oldest fossils because this layer has the smallest number of vertebrate fossils. CYes. The Hawthorn Group must contain the oldest fossils because it is the lowermost layer of soil and rock excavated by the scientists. No. The Tamiami Formation must contain the oldest fossils because it contains the greatest number of vertebrate fossils discovered. No. The Miami Limestone must contain the oldest fossils because it is the uppermost…

as Tutorials Which of the following is NOT TRUE for modern taxonomy? O Modern taxonomy combines the evolutionary history of taxa with knowledge of plate tectonics and paleo-ecological data e 365 st-All HQ O Modern taxonomy is based on phylogeny which incorporates data ranging from fossils to molecules to genes to derive evolutionary relationships ry Resources O Modern taxonomy is focused on patterns of descent in contrast to Linnaean classification which was solely based on morphological traits ter Dashboard es-WLAC O Modern taxonomy is based primarily on morphological data which are highly correlated with genetic relatedness
