What are the potential implications of the H. luzonensis and H. floresiensis discoveries on our understanding of the human evolutionary timeline and interactions between different hominin species? (Minimum of 2 complete sentences.)

Choose any fossil hominin species (except Homo sąpiens sapiens) and describe what we currently know about that species, including the information below. • morphological characteristics (cranial traits and post-cranial traits) • any famous fossils and why they are famous • dates relative to other species (in general - chronological order) . lifeways/cultural characteristics (i.e. shelters, tools, hunting & scavenging, etc.) • where they are found (in general – geographic range) For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac). BI Y S Paragraph Arial 10pt A x' X2 ABC QUESTION 62 Choose one of the questions below to answer. Describe least five factors that can influence variation in growth, development, or the timing of events/phases during the human life course. Be sure to describe how each of these factors actually affects patterns of growth, development, and the life course in your answer. or What is the first, second, and third epidemiological transition?

What genetic changes madeus uniquely human? What furtheraspects of our recent evolutionarydevelopment can be reconstructedby sequencing DNA from remains ofancient hominids?

I can apply the knowledge of Patterns of Descent withModification from Common Ancestors & The Development of EvolutionaryThought by:

If phenotype is a proxy for genotype, then why do you think that paleoanthropologists erroneously designated Neandertalensis as a separate species prior to the accessibility of DNA analysis?  What were they comparing them to when they were lumping or splitting fossils taxonomically and why would these reference populations provide the bias resulting in such a confounding factor in their assessments?

A number of comparisons of nucleotide sequences among hominidsand rodents indicate that inbreeding may have occurredmore often in hominid than in rodent ancestry. Bakewell et al.(2007. Proc. Nat. Acad. Sci. [USA] 104: 7489-7494) suggest thatan ancient population bottleneck that left approximately 10,000 humans might have caused early humans to have a greaterchance of genetic disease. Why would a population bottleneckinfluence the frequency of genetic disease?

48. During the late Cretaceous Period, the quadrupedal dinosaur Triceratops horridus (fossils dating from 68.0 to 67.0 MYA in Wyoming's Lance Creek Formation) evolved into the heavier Triceratops prorsus (fossils dating from 67.0 to 66.0 MYA in Montana's Hell Creek Formation), with no apparent branching of additional species in this lineage. The gradual disappearance of one light ancestral species (Triceratops horridus), and its gradual replacement by one heavier descendant species (Triceratops prorsus), perhaps in response to the newly-arrived predatory dinosaur Tyrannosaurus rex, in about the same geographic region, is probably an example of: A. disruptive selection leading to branching speciation B. diversifying selection leading to cladogenesis C. directional selection leading to anagenesis D. stabilizing selection leading to stasis E. all of the above

Compare and contrast hominin evolution through the years using the following criteria: Species Social and cultural behaviour Anatomy (ex. skull) Habitat

Question 4 The sequenced genomes of many vertebrates have multiple Hox gene clusters. Why might these have been selectively advantageous in the evolution of vertebrates? In case of a Hox mutation, an embryo is more likely to be able to develop normally. A B) Having multiple Hox clusters ensures proper mouth-first gastrulation of the zygote. Having multiple Hox clusters allows vertebrates to evolve faster. D) In case of a Hox mutation, an embryo will be able to evolve new traits. 2 Points Question 5.

INSTRUCTIONS: - Don't copy in Google or here in Bartleby - Answer the question properly QUESTION: Human immunodeficiency virus entered human populations after evolving from a simian immunodeficiency virus. Nikolaas Tinbergen (1963), proposed explaining shifts in traits from two perspectives: dynamic versus static, and proximate versus ultimate. This framework can be used to understand the evolution of a trait in four ways: (i) causation (proximate/static): the mechanism of the trait as it works in the present; (ii) survival value (ultimate static): how function of the trait enhances survival or reproduction; (iii) ontogeny (proximate dynamic): the development of the trait in an individual; and, (iv) evolution (ultimate/dynamic): the phylogenetic history of the trait. Use these categories to discuss the causes for the virus shifting to humans from other primates.
