Natural Selection: Imagine that a population of Cnidarians with life cycles that alternated between sexual and asexual reproductive phases evolved from ancestors whose life cycles lacked asexual phases. Explain how this may have occured via natural selection. In your answer be sure to address all of the key points discussed in class as being necessary to describe evolution by natural selection

Natural Selection: you noticed a worms population displaying metamerism evolved from non metameric ancestors. Explain how this happened via natural selection. Mention key points necessarily used to describe evolution by natural selection.
Give a Darwinian explanation of how cheetahs evolved to become faster. Your explanation is how natural selection works using Cheetahs as an example. Be sure to include and explain the ideas of differential reproductive success and descent with modification. (You do not need to mention the formation of new species.)

Discuss how the results of this simulation are an example of evolution? Simulation: For this lab, the dominant allele for normal fur pigmentation (gray) is represented by G and the recessive allele for leucistic pigmentation is represented by g. Squirrels that inherit two G alleles (homozygous dominant) or one G and one g allele (heterozygous) have normal pigmentation, while squirrels that inherit two gs (homozygous recessive) have leucistic pigmentation. Due to the difficulty of leucisitc squirrels to camouflage themselves against predators, in each generation, 50% of the gg individuals will die off from predation before they can reach maturity. This means they will not be able to pass their genes on to the next generation.
Some worms eat at night (meaning they are nocturnal) and some worms eat during the day (meaning they are diurnal.) Most birds eat only during the day, so they are only eating diurnal worms, due to the fact that the nocturnal worms are burrowing during this time. Each spring when the worms reproduce about 500 offspring are born but only 100 of them live long enough to reproduce themselves. Explain how natural selection will occur and include the 4 principals of natural selection.
The fact that geneticists may be able to activate and inactivate genes in a chicken embryo to re-create a dinosaur is the most important to evolutionary scientists because: Question 18 options: This would help provide evidence on a genetic level that could prove the theory of evolution. Of all birds, we have the most complete genetic data compiled for chickens. Of all chordates, birds (like chickens) are the most like dinosaurs. This will help to prove the theory of punctuated equilibrium.
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.
Background: In class we did a project about m and m’s and there ability to evolve and natural selection. (Yes I know they can’t actually evolve it was just used as a example in class) however I can’t figure out this question. Occasionally a mutant may occur and produce a candy that is misshapen or Pointier or flatter than the rest. Often this proves to be a weakness, but a rare mutation may confer extra M&M durability. Other mutations in M&Ms could occur ( like ones that result in a new color). A mutant un you population represents a new _________. What goes in the blank

Evolution in Humans 1) explain what evolutionary mechanisms are involved in creating variation in populations 2) define homology and analogy and discuss examples of each
What evolutionary mechanism is occuring in each of the following examples, justify your answer: In a population of Darwin’s Finches (Geospiza sp.) there is a large variation in beak size. Grass and mallow seeds can only be eaten by finches with small beaks. Seeds from thorn shrubs can only be eaten by birds with larger, thicker beaks. During a series of years with less rain, grasses and mallows are unable to reproduce and so only thorn shrub seeds are present. Over the course of this drought, the average size of finch beaks becomes larger. Columbine flowers are pollinated by hummingbirds and hawkmoths. Hawkmoths prefer to pollinate yellow flowers, while hummingbirds prefer to pollinate red flowers. Most flowers in a certain population are an intermediate orange color to attract both pollinators. Ensatina from one population are able to survive by camouflaging with their backgrounds. Ensatina from the other population are bright orange mimics of a poisonous newt (Taricha). Hybrid…
