1- Consider natural selection and biocultural evolution. Why do you think anatomically modern humans were more reproductively successful than other contemporary hominins? Or were they? 2- Why do you think such a small portion of Neandertal or Denisovan DNA exists in the gene pool of modern humans? Why not more? 3- How might have anatomically modern humans avoided waiting tens of thousands of years for advantageous mutations to pop up that would allow them to adapt to all of these new environments they encountered as they dispersed across the Old World? What might have been a faster way for them to adapt to these environments that the groups who were already in the region had already adapted to?

Genomics and Human Evolution The Denisovan genome contains sequences that originated from an unknown human species. Using Figure 19.11, speculate on which species this might be. Is it possible that there are other ancestral species that may remain to be discovered that would change the phylogeny presented in the figure? FIGURE 19.11 Estimates for the dates of origin and extinction for the three main groups of hominins (green, blue, and orange). The australopithecines split into two groups about 2.7 million years ago. One of those groups, the genus Homo, contains the ancestors to our species, H. sapiens.

The ~100 Neanderthal remains from the site Krapina, Czech Republic, exhibit an abrupt change to a more modern appearance approximately 40,000 ybp, indicating that Neanderthals were completely replaced by Anatomically modern humans. exhibit a slow transition from Neanderthals to more modern appearance over time. were all slaughtered by an incoming hoard of Anatomically Modern Homo sapiens. demonstrate that Neanderthal mitochondrial DNA is not found among any living human populations. provide evidence for care of the elderly.
hat I Can Do The evolution of man is one of the most fascinating discussion and discovery in the field of science. Humans as the race that have dominated the Earth and seem to be at the center of it have evolved greatly. Observe the illustration on the left. The common ancestor of the primates like chimpanzees and humans might look like a primitive primate with four limbs on which the forelimbs are used to hang on trees. After some time, the emergence of humans has marked a great change on the history of life on Earth. In your point of view as a senior high school STEM student, are humans still evolving? Provide evidences for your answer.
Evolution in Humans 1) explain how differences in gene expression of genetically similar organism can result in different evolutionary outcomes 2) describe the evolution of symbolic thought in humans
Microtaxonomy ( Species and Speciation ) People who do not believe in evolution often cite the classic example of man presumably evolving from the apes. They oftern ask: if humans evolved from apes, why are there apes until today? How will you provide a convincing answer that there is no contradiction in the existence of apes and humans at the same time?
Evolution in Humans 1) explain how fossil evidence is used to reconstruct the hominid history 2) explain how genetic evidence is used to document changes in species and populations over time 3) describe several techniques that paleontologists today use to establish fossil age
2. Birds have evolved over the last 60-70 MY. To learn about their relatedness, we can use DNA sequences. Because DNA evolves at a relatively steady rate, gene sequences in two different organisms will accumulate sequence changes and become more different with time. The longer ago their common ancestor was, the more different their sequences will be. However, some genes are under more selection and so evolve slowly. Other genes are under less selection and so evolve quite quickly. Assuming that sites change linearly with time, we can calculate how many sites differ when comparing genes between different species. For simplicity we'll assume we are comparing 1000bp of sequence for each of these genes. Species compared Canary and olive finch Canary and house finch Canary and zebra finch Canary and robin Canary and chicken a. Why do the three genes differ in the number of variable sites between different species? Canary Olive finch House finch Zebra finch robin chicken Canary # of sites…
The "molecular clock" of the rate of change in a segment of DNA during evolution depends on which of the following? (select all that apply) • A process called purifying selection • Whether that DNA contains functionally important sequences • Whether the DNA can be easily sequenced • The structure of the RNA molecule produced from that DNA The rate that mutations occur in that species or type of DNA Message @ProBot ✨
Hi! All of these are related to a single subject. I hope it includes the three subparts I'm allowed for. Thanks! Identify the structure, how and where are they similar? In stage 3, identify the structures that made the organisms different from each other? Can embryonic development be an evidence that evolution took place? Explain.
