EVOLUTION LINK Charles Darwin once said, It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change. Explain what he meant.
Both Darwin and Wallace, while observing life on islands, concluded that natural selection is the mechanism for biological evolution. The Hawaiian and nearby islands once had at least 30 species of honeycreeper birds and lived nowhere else on earth. Natural section occurs everywhere in all species. What characteristics of islands allow the outcome of natural selection to be so obvious?
Which of the following is NOT a component of the Theory of Evolution by Natural Selection? competition for food and space variation among species inheritance of acquired characteristics survival and reproduction
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.
Although Charles Darwin is best known for developing his theories of evolution during his trip on the HMS Beagle, his later life also provided evidence for evolution. Explain how Darwin’s later life added to his evolution theory.
Which of the following concepts characterized Lamarck’s hypothesis about evolution? Select all that apply. 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. Over many generations, individuals that have more adaptive traits tend to survive longer and reproduce more than less fit rivals.
Which of the following BEST describes the theory of natural selection? Living organisms change over time. Each species produces many more offspring than can survive long enough to reproduce. The offspring that do survive contain genes that are inherited from the parents. There is variation among the members of a species. Some of this variation is genetically determined and so can be passed on to future generations. Some individuals have genes that increase their chances for survival and reproduction. These individuals are more likely to reproduce and pass on their genes, causing their genes to become more common in the next generation. There is a struggle for existence among the members of a population.
Alfred Russel Wallace and Charles Darwin argued that evolution by means of natural selection involves all of the following steps except: a. variation is present in all species b. species can produce more offspring than the environment can sustain c. all individuals within a species have equal chances to improve their fitness d. those individuals that are more fit will survive and reproduce in the greatest numbers e. over time, the species will evolve as the more fit individuals replace the less fit individuals
A small population of wood rats boarded a ship leaving Europe and ended up in South America where they began breeding. Which type of Mechanism evolution is this. Natural Selection Genetic drift Gene Flow Bottleneck Effect Founder Effect Sexual Selection
In which of the following scenarios would evolution by natural selection take place? A banana tree branch is planted, producing a clone of the parent tree Microorganisms reproduce asexually, producing identical offspring Corn is genetically modified and cloned to make identical crops Penguins reproduce sexually, producing offspring that look different from one another
Darwin’s idea for the mechanism of evolution is called the Theory of Natural Selection. One important part of the theory says that there is variation in a population. In sexually mating eukaryotic organisms, where does most of the variation come from?
Out of the three, what would be an example of evolution? A population of green beetles changes over many generations to a population of brown beetles. Individual green beetles in a population become brown because of what they are eating. The environment where a population of green beetles is living changes, becoming much more cold over time.
