Which observation is NOT an evidence for Darwin's theory of common descent? Group of answer choices There are biogeographic patterns in the distribution of species, for instance distinct bird species on an island tend to resemble. Anatomical structures, such as forelimbs, in different groups appear to be modified versions of structures that might have been present in a common ancestor. There are common stages in the early embryological development of organisms representing several distinct vertebrate groups

Which of the following is NOT an evidence for Darwin's theory of common descent? Group of answer choices Due to innate drive to improve, parts that are extensively used becomes larger and stronger and passed on to the next generation as seen on fossil records. Anatomical structures, such as forelimbs, in different groups appear to be modified versions of structures that might have been present in a common ancestor. There are biogeographic patterns in the distribution of species, for instance distinct bird species on an island tend to resemble one another, suggesting a common ancestor. There are common stages in the early embryological development of organisms representing several distinct vertebrate groups.
Charles Darwin and Jean Baptide de Lamarck have different ideas of explaining evolution. Describe how each of them explained the evolution of long necks of giraffes. Justify whose idea is more acceptable in science community.
The two primates shown below both exhibit large eye orbits. One is a tarsier, the other is an owl monkey (the only nocturnal platyrrhine). Why do these primates share the trait for large eyes? Mark the best answer. Group of answer choices Random mutations, since having large eyes is abnormal in these species of primate. Convergent evolution, since both separately evolved large eyes to adapt to a nocturnal activity pattern. Both inherited this trait from their common ancestor, which was also nocturnal with large eyes. Unclear, cannot determine from the information given.
Which concepts characterized Lamarck's hypothesis about evolution? Select all that apply. Over many generations, individuals that have more adaptive traits tend to survive longer and reproduce more than less fit rivals. Environmental pressures caused an internal requirement for change in an individual, and the individual would change to meet this pressure Species gradually improved over generations due to an inherent drive toward perfection. Changes acquired to meet environmental pressures during an individual's lifetime would be inherited by offspring.
Compare and contrast Lamarckian and Darwinian theories of evolution. Give an example of each. Do not use any examples addressing: giraffes, elephants, birds or humans. Be detailed in your answer
. The images below show two separate theories of how organisms evolve. Which question below directly corresponds to whether Lamarck or Darwin are correct about their theories of the mechanisms of evolution? Why don’t the shorter neck giraffes feed on grasses and lower vegetation? How would the shorter necked giraffes in Lamarck’s theory survive to reproduce and pass on the “need” for longer necks if they were unable to reach food? Why won’t the taller necked giraffes in Darwin’s theory provide assistance to the shorter giraffes since they are the same species? Will the smaller giraffes be more adapted to hide from predators since they wouldn’t be visible from greater distances?
What Darwin Never Knew. List all ways you can think of observations from nature ,development,etc that were important for Darwin when he developed his theory of evolution by natural selection. Why are the Galápagos Islands unusual? How were they significant for the formation of Darwin’s theory ? Why were the finches important to Darwin theory ? Why did the beaks of the finches look different?

Which of the following is NOT an example of evolution? Group of answer choices Increased wealth in children of wealthier parents Transitional forms in the fossil record Increase in frequency of large beaked finches after a drought Homology in forelimb structures in different tetrapods (4-limbed vertebrate animals)
Why are fruit flies good subjects with which to observe the process of evolution through natural selection? Fruit flies are good subjects because they have very long generations, and scientists can control their development over long periods of time. Fruit flies are good subjects because they have short generations and scientists can control their development in the lab. Fruit flies change into different species of flies each generation, so they have more features to study. Fruit flies are K-strategists, and these are easier to study over short periods of time.
Utilize the space provided to contrsuct your written explanation based on natural selection high incidence of tusk less ness among female elephants in Gorongosa. Explanation should include at least two points of scientific reasoning to link the evidence to the claim.
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.
