Summary Introduction

To determine: The way, a compound eye of human, fly, and the eyespot of the ribbon worm could have a common evolutionary origin.

Introduction: The eyes are the sensory organ. The insects are the vertebrates show divergence from a common ancestor. There is large differences in vertebrate's eye and insect eye.

Regarding the evolution of the mammalian inner ear, the above diagram shows:A) the co-option of jaw bones (colored) for use in hearingB) the loss of jaw bones (colored) and the origin of de-novo hearing bones C) the evolution of synapsids, which have little to do with mammalian evolutionD) the results of a population bottleneck which led to the fixation of odd alleles for ear development
Eyes are often used in arguments for intelligent design because many consider this organ to be too complex to have evolved by chance alone. However, complex lensed eyes evolved independently both within cephalod mollusks and vertebrates including our own ancestor. In the evolution of these structures the corresponding phylogenies revealed that both:     A) were preceded by the evolution of 'simple' light sensing eyes, thus having adaptive intermediate evolutionary steps.     B) lacked intermediate evolutionary steps involving the evolution of 'simple' eyes.     C) had intermediate evolutionary steps, but ultimately the vertebrate eye had a superior 'design' without any kind of blind spot, relative to the simple invertebrate cephalopod eye.     D) were preceded by vestigial non-functional optic structures.
The phylogeny in this figure shows the evolution of visual opsins in tetrapods. Each colored triangle represents a different opsin. Which of the following accurately describes the opsins in these species?

The green opsin is a synapomorphy in rodents and New World primates, and the light blue opsin is a symplesiomorphy in baboons and humans. b. The light blue opsin is a synapomorphy in squamate reptiles and birds, and the green opsin is an ancestral trait. OC. The purple opsin is an analogous trait, and the green opsin is a homologous trait. Od. The green opsin is a synapomorphy in baboons and humans, and the light blue opsin is symplesiomorphy in squamate reptiles and birds.
