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.

Which term best applies to what you saw in both images? Explain how. Vocabulary terms: Natural Selection, Adaptation, Fitness, Genetic Diversity, Phenotype, Polymorphic, and Selective Pressure

A group of one species of bacteria are exposed to an antibiotic.  The normal bacteria die but some are resistant to the antibiotic and start multiplying.  The resistant bacteria flourish and now make up the majority of the population.  This is an example of what?     Speciation     Reduction of Gene Flow     Natural Selection     Geographic Isolation

Characteristics like the panda's "thumb" and the seven long bones in a giraffes neck show us that; Evolution is goal oriented There could indeed be a perfect organism that evolves some time in the future Evolution leads to imperfect adapations The phyletic gradualism model of speciation is most likely correct

When the Galapagos Islands were surveyed by Darwin, he noted 13 species of finches. Later he published the proposal that: too many species of finches overcrowded the islands finches probably evolved from one ancestral South American species the 13 finch species were identical to those he observed in northwestern South America 600 miles to the east finches evolved wings adapted for flying between specific islands all finches adapted to the same food sources

Siberian tigers are the largest of all tiger species because only the largest individual are able to survive the cold harsh winters of north eastern Russia. what type Mechanism evolution is this Natural Selection Genetic drift Gene Flow Bottleneck Effect Founder Effect Sexual Selection

Jean-Baptiste Lamarck’s model for large-scale evolutionary change involved: dynamic, monophyletic, branching speciation dynamic, polyphyletic, non-branching speciation static, monophyletic, branching speciation static, monophyletic, non-branching speciation static, polyphyletic, branching speciation

A farmer wants to make a better corn plant that produces more and bigger kernels. In the chart, information is provided on two ways organisms can change over time. Natural Selection Selective Breeding Humans are not involved in the evolution process Human intervention is involved More generations are involved in natural selection, so it is a slower process Selective breeding is a faster process Survival of the fittest increases species' chance for survival Adaptations may not necessarily improve survival Mutations that result in natural selection occur randomly The desirable charactenstics are artificially chosen What is the best way for the farmer to improve his crop and why? Use evidence from the table to support your reasoning. Please write in complete sentences.

Which part of these statements isn't right ?       A species is a group of organisms that can potentially interbreed with one another to produce viable, fertile offspring. Speciation is when two new species form from one original one. Sympatric speciation occurs when there is a geographic separation of a population. Allopatric speciation occurs while the population remains in the same area. Adaptive radiation occurs when one species evolves into many to fill several different niches. Natural selection requires traits to be passed from parent to offspring, more offspring are produced than can survive creating competition, and inherited traits vary among offspring. Fossils, Anatomy and embryology, biogeography, and molecular biology all provide support for the theory of evolution. Evolution can be driven by many different things. Mutations are changes in DNA that create new alleles in a population. Gene flow is the flow of alleles in and out of a population resulting from the migration…

What evidence did Georges Cuvier present that contradicted one of Jean-Baptiste Lamarck’s ideas? he argued that specimens in the fossil record never changed much, so evolution was not occurring he demonstrated that the Indian elephant and the African elephant were two different species he claimed that divine creation was necessary to explain the origin of a new species he argued that natural catastrophes, like floods and ice ages, were common in the history of life he identified fossil specimens of two large, extinct mammal species (the mammoth and the mastodon)
