Explain evolution in terms of natural selection, genetic mutation, and speciation. Give an example of each process which resulted in a species evolving to best survive in its' specific habitat.

During the evolutionary synthesis, biologists conclusively identified natural selection, gene flow, genetic drift, and mutation as the major causes of evolution within species. Using the scientific definition of evolution, explain how these forces cause populations, species, and higher taxa to evolve.
For 3. Define the terms fitness, adaptation, natural selection, and evolution. 4. Why is variation so crucial for the survival of a species? 5. If the environment changes, is it certain that a species will adapt to it and survive? Why? 6. Does modern medicine affect natural selection in the human species today? Explain.
this is an evolution question Allopatric speciation is probably the most common way that new species form. Please describe a hypothetical scenario in which an initial ancestral population (pick whatever species you want) could split to form a new species through allopatric speciation. A fully. correct answer will at least incorporate ALL of the following terms: gene flow.divergence, natural selection (including sexual selection), genetic drift, and reproductive isolation
Of the following evolutionary forces; crossing over, directional selection, mutation, speciation, stabilizing selection, sex, gene flow and genetic drift which promote or maintain genetic variation within a population? a) crossing over only b) directional selection and sex c) directional selection, mutation, and speciation d) crossing over, mutation, sex, and gene flow e) only sex Of the following evolutionary forces, crossing over, directional selection, mutation, speciation, stabilizing selection, sex, gene flow and genetic drift which promote genetic differentiation (divergence) among populations?...
Describe the four basic causes of evolution: natural selection, mutation, genetic drift, and gene flow. The paper should be 400- 500 words (~ 1 double-spaced, APA formatted page). Refer to the attached document for the grading rubric.
Match one of the following terms to each part: Natural selection, speciation, disruptive selection, allele frequencies, directional selection a)Through time organisms change morphology making them different species is called? b) When an organism is fit and withstands change in their environment they can adapt and are selected to live longer and breed more is called? c)When traits change in populations the genotypes change which leads to this in the population?
explain difference between natural selection and genetic drift and how each can influence evolution in different ways. Should not be less than 200 words
Technical: Create a concept map with these terms: genetic drift, adaptation, mutation, gene flow, natural selection, inbreeding. Make a minimum of 5 connections Reflection: One paragraph: Think of an example that you have witnessed where an environment seemed out of balance in terms of # of autotrophs, or heterotrophs. If you cannot remember a situation where you noticed this, think about your neighborhood. Look outside, what do you see in terms of balance of trophic levels? Include the following in...
help 4.) Darwin's Theory of Natural Selection stated that: a.) At one time the earth held all the species and each catastrophic event would destroy certain species - survivors would repopulate the world b.) Environmental pressures and internal needs bring about changes in body form and function and this is passed on to their offspring c.) Process in which individuals with favorable inherited traits are more likely to survive and reproduce at a higher rate than other individuals 5.) Convergent...
What are the common myths about evolution and why are they wrong? Name and describe the three results of natural selection that can create changes in the percentages of alleles in a population? What are the allopatric and the sympatric speciation? Give examples of each. What are the two major types of barriers that result in reproductive isolation? Give several examples of each type that prevents the result of healthy, fertile offspring between two different species. Trace our hominid ancestor...
