The hypotheses that account for the observation that more genes have experienced recent adaptive evolution in the chimpanzee genome than in the human genome. Introduction: Chimpanzees are the closest living relative of the humans because they share 96 percent identical DNA sequences with humans. The sequencing of the genome of the chimpanzee is the biggest achievement because it is implicated for human health, and many interesting discoveries have been done to know humans well.

Question

An adult human has a flat face with a small jaw and large cranium. An adult chimpanzee has a large jaw and small cranium. Both juvenile chimps and humans have heads similar to adult humans. Which of the following is a reasonable explanation for this pattern? Group of answer choices A) genes that modify skull shape are not expressed in chimps during development B) head shape is controlled by cytoplasmic determinants C)genes that modify skull shape are not expressed in humans during development D) chimps and humans have completely different genes controlling the formation of the head

Summary Introduction

To explain: The hypotheses that account for the observation that more genes have experienced recent adaptive evolution in the chimpanzee genome than in the human genome.

Introduction: Chimpanzees are the closest living relative of the humans because they share 96 percent identical DNA sequences with humans. The sequencing of the genome of the chimpanzee is the biggest achievement because it is implicated for human health, and many interesting discoveries have been done to know humans well.

How, specifically, is the concept of ALLOMETRY relevant to the phylogenetic position of Homo floresiensis? 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.

We have studied how the six major primate groups evolved, with the most recent group being the hominins.The hominins branched off from main ape group around 7 million years ago.According to our lessons explain your reasoning as to whether there is a missing link,or one single specimen that embodies both ape and hominin traits, that serves as a transition between what is clearly ape and what is clearly hominin?What have you found most interesting about the beginning of hominin evolution and why?
