(a) they evolved from saurischian dinosaurs (b) they are exotherms (c) they have hair and three middle ear bones (d) mammalian embryos do not have an amnion (e) they all bear their young alive (do not lay eggs).arrow_forwardINTERPRET DATA Imagine that you discover a new animal in a rain forest. It has an elongated, segmented body with bristles, and it has no obvious head. Where would youplace this animal in the accompanying cladogram? Support your decision.

- Expound and Elaborate: Mammals belong to a group of amniotes known as synapsids. Three major lineages of mammals had emerged by the early Cretaceous period. In a tabulated form, compare these three lineages to illustrate their diversity in terms of:a. Embryonic developmentb. How the young are fedc. Period of gestationarrow_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).

- Species Embryo (A-F) Describe the Anatomical Changes from Early to Late Stages Human Chicken Rabbit Tortoise Salamander В Fish A Guide Questions: 1. Look again at the six embryos in their earliest stages. Describe the patterns you see. What physical similarities exist between each of the embryos? 2. Does this suggest an evolutionary relationship? Explain how these embryos can be used as evidence of a common ancestor between each of these six organisms.arrow_forwardWhat are your thoughts on the followig paragraph below? Understanding the classification of primates in this module helped me digest past modules' material on taxonomy. I learnt that there are differenet divisions, orders, and categories of primates. The two suborders of primates are Strepsirhini and Haplorhini. This furthered my understanding on what makes us human and what similarities and differences we share with other primates. I had heard of many of these factors before such as bipedalism and being able to use tools, but one I hadn't heard of is knucklewalking. This term refers to a way of walking on all 4s commonly used by African apes. It was truly interesting to see how closely we are related to monkeys from our behaviors, features, and mroe. An aha moment I had was learning about the number of primates that include 230 species. The way they are geographically spread was even more interesting. Apes are common in South Africa and South Asia even though these 2 places are…arrow_forwardSee attached. 1. Which pair of animals in numbers 1-3 belongs to a common ancestral group?
