#21 Answer the following questions about evolution. Number responses according to the questions (1-4). (short answers are fine) How can negative traits that don't show up until old age continue in populations? (Why aren't they eliminated through natural selection?) As part of answer, provide an example. Imagine a population of mice living in a grey, rocky environment. Some mice are grey and some are brown. If natural selection occurs in this population, what would someone expect to see if you returned in 100 mouse generations? Describe what someone see in terms of fur colors in the population. Imagine a population of mice living in a grey, rocky environment. Some mice are grey and some are brown. If mutations occur in this population, what could someone see if they returned in 100 mouse generations, that would tell them mutations had occurred? Describe what they would see in terms of fur colors in the population, and how it would be different from what they would see in #2. If…

Why is it that the evolution of skin color is considered a case of natural selection? Group of answer choices A- Because different alleles in skin color genes lead to differences in skin color B- Because differences in skin color lead to differences in number of children in different environments C- Both D- Neither
Some of the mechanisms that help repair wounds or fight off infection can result in cancer when we’re old. Why hasn’t evolution eliminated these processes? Hint: Do conditions of postreproductive age affect natural selection?
Please help with the following prompt using as much details as possible. "One argument that is often made to invalidate evolution by natural selection is that some features of an organism are so complicated and need to work together in order to precisely function that it is impossible for such structures to arise from simpler ones by the random processes of mutation and selection: complicated design requires a designer. Using evidence from real organisms, explain how a complicated structure can arise from a simpler ancestral feature. You can use either an anatomical feature or molecular one."
Revise the passage Darwin is best known for his Theory of Inheritance of Acquired Characteristics, first presented in 1801 (Darwin's first book dealing with natural selection was published in 1859):Based on these observations and inferences, Darwin concluded that these traits, called adaptations were the product of evolution by Acquired Traits, these traits made the members of the population who had them equally fit for survival. an organism could also change during their lifetime in order to adapt to its environment, those changes are passed on to its offspring. For example, darwin believed that if giraffes stretched their necks to reach food, Their offspring and later generations would inherit the resulting long necks.
Explain the misconception on why the Theory of Evolution is deemed as "just a theory" rather than as a "scientific fact." How from simple apelike ancestors Homo Sapiens or the " Thinking Man" came into being.
What are the 4 Mechanisms of Evolution? 1. 2. 3. 4. 1) OVERPRODUCTION - What leads to over overproduction? Observations Overproduction of offspring 2) Variation needs to be: Individual variation : When a genetic trait becomes more abundant in a population because it helps you to get : About Genotype - another population. Tends to... Conclusion. Natural selection: unequal reproductive success : About Phenotype - Is genetic exchange with
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?
Regardless, many people have a problem with the idea of evolution. Why? To complete it, answer some of the following questions: Why is evolution so controversial? Does understanding it better make it less controversial? What were you taught to think/believe about evolution? Why?
Definitions of phenotype, genotype, allele, gene, microevolution, macroevolution - Know that in humans, most of the genetic variation is observed within populations, and know why that is. - Know the 4 processes of evolution (3 neutral + natural selection) - Know that evolution isn’t progressive and doesn’t necessarily lead to more complexity - Know that evolution can lead to traits that decrease survival (ex: sexual selection) - Know that quantitative traits are generally influenced by (i) many genes, each having a small effect on the trait value; and (ii) the environment - What is F1 like when you cross 2 homozygotic lines of peas of different colors? - What is F2 like when you cross F1 individuals (remember what 9:3:3:1 is about) - Know what genetic dominance is about - Definitions of chromosome, nucleus, mitosis, meiosis, crossing over - How many chromosomes in humans? How many pairs of chromosomes? - Know and apply Hardy-Weinberg’s equation - Why do quantitative…
Which the following statements about Darwin's theory of natural selection is true? O In order to reproduce more successfully, an individual must evolve so that it adapts to its environment. The natural environment consistently causes variation of certain traits in the population. O Individuals with inherited traits that are better suited to the local environment are more likely to survive and reproduce than less well-suited individuals. Natural selection, by its cumulative effects over long periods of time, could have caused random changes in ancestral species, thus giving rise to two or more descendant species.
