Explain how the broad evolutionary changes seen in the fossil record are the cumulative result of speciation and extinction events.
Homework Answers
Answer- Fossil records tells about the types of organisms which existed in the past. The types and abundance different kinds of fossil records tells about the survival and extinction of species, the species which had long survival that is stored in large Fossil records while the species which had less survival rate and more extinction rate are very less recorded in the fossil.
Fossil records of different evolutionary time are recorded in different layers of soil. Speciation the evolutionary past leads to addition of more Fossil records while extinction in the past leads to less Fossil records. Whatever we see in the present were survived organisms in the past, which were result of cumulative effect of both speciation and extinction events in the past.

7. After mass extinction events, evidence from the fossil record shows: O diversity, in terms of genera, increased to levels above what was present just before the previous extinction. O descendants of lineages surviving the extinction event gave rise to entirely new lineages of animals. O groups of organisms replace each extinct group with a new, more derived, descendant group. O new animal phyla evolved after each extinction event.

Discuss whether changes to an organism's physical environment are likely to result in evolutionary change. Use examples to support your reasoning. Second, using at least two examples, explain how the process of evolution is revealed by the imperfections of living organisms

Review the long-term atmospheric CO2 record. What evidence is there that burning of fossil fuels is responsible for recent increases in atmospheric CO2 concentrations? Describe why rapid changes in global temperatures will likely lead to the extinction of large numbers of species? How might changes in global temperatures specifically affect each of The Anolis lizards we studied this semester The Gorongosa ecosystem What are two ways human societies can mitigate these impacts on large scales now?

Draw a model or concept map linking at least these evolutionary concepts. You are free to add more. When you make a link between two ideas you must write what links the concepts above the arrow. Just drawing arrows does not help build your understanding.

Regarding the evolutionary history of biological diversity (cladogenesis and extinction), would you say biodiversity changes are typically rapid or slow? a) Gradual or punctuated? b) Give an example of each. c) In comparison to adaptive radiations per se, what additional process occurs with punctuated equilibrium? d) What are two hypotheses thought to explain stasis of organisms, particularly those that have not changed substantially over the last 100 million years?

5. Differentiate between the processes and results of microevolution and macroevolution, and explain how these contribute to speciation. • Explain why individuals do not evolve? At what level does evolution occur? • What are gene pools? Describe microevolution. • What is macroevolution including speciation? What are novel features? 6. Relate the geologic history of the planet to evolutionary history, including mass extinctions and subsequent diversification. • What is the role of mass extinctions and diversification in macroevolution? • How does...

Please answer all the questions not partly Q. 1 The number of species on the planet could be estimated by: Question 1 options choose one contrasting the background extinction rate to the modern extinction rate counting the number of dispersal and vicariance events comparing speciation rates to extinction rates considering the mutation rate and extent of genetic drift Q 2 All of the following are likely to cause mass extinction EXCEPT: Question 2 options:choose one many volcanoes erupt over a...

Please explain the follwing question as if it were written in an essay format. Provide as much info as possible to support your claims. Natural selection occurs when the genetics of a population intersects with the ecology of their environment. This in turn can lead to larger evolutionary changes such as speciation. Using a specific example, explain how novel genetic traits, natural selection and adaptations have led to adaptive radiation and the origin of higher level taxa such as phyla...
