Question
Chapter 15.5, Problem 2MC
Summary Introduction
To determine:
In what way the genome sequence of Orangutans and Gorillas help scientists further resolve the evolutionary history of humans.
Concept introduction:
The sequencing technology has greatly revolutionized the field of evolutionary biology as the genome sequences from organisms can be compared to evaluate their evolutionary relatedness. The sequence can also help in determining the genes that played an important role in acquisition of a particular trait such as development of complex language, socialism and cognitive ability.

Because if allometry explains the anatomy of Homo floresiensis then we can conclude that it is not separate species but instead a member of our species. Although most mammals on islands go through a process of getting smaller, Homo floresiensis evolved from a smaller ancestor to be bigger, meaning that allometry is an important factor. Mutations in the allometry allele are associated with many of the characteristics of Homo floresiensis. Because Homo floresiensis is so much smaller than other members of the genus Homo, it is important to determine how shape changes associated with smaller size impacted the species. Because Homo floresiensis had both small- and large-bodied forms, variation within the species is in large part dictated by allometry.arrow_forwarda) Based on this tree is the chicken, mouse, human, or hamster most closely related to the bat? b) Which of the following statements is NOT true? -chicken, dogs, and humans share a common ancestor -mice are more closely related to bats than they are to bears -macaques are equally related to humans and chimpanzees c) Which of the following statements is NOT true? - bears are equally related to tarsiers and humans - tarsiers are more related to dogs than they are to bats - chickens are more closely related to bats than they are to chimpanzees - tigers, dogs, and bears form a monophyletic grouparrow_forward
