- Describe the general pattern of diversity from theequator to the poles. Provide two hypotheses to explain thispattern of diversity.Homologous genes that arise from speciation and gene divergence are called _____.A scientist is attempting to a cladogram that shows the evolutionary closeness of three organisms in relation to humansAfter doing DNA analysis, they that the organisms share the following percentages of DNA Organism A and humans share 85% of their DNA Organismn and humans share 80% of their DNA Organism and humans share 90% of their DNA Based on informationwhich order should they go on the cladogram ( related to most related ?
- do taxa E F G by themselves form a monophyletic group (clade)? why or why not? Trait 2 E Trait 1 Ancestor 3 Ancestor 1 (Trait 2 not present) Trait 1 Trait 2 Trait 1 Ancestor 2 Trait 1using venn diagram, give similarities and difference of two theories (Natural Selection and Artificial Selection)What happens to potential of Evolution when heterozygosity is reduced?
- A reasonable definition for a species is: O A distinct kind of animal. O A group of living things with functionally similar traits, for example, all creatures that can fly. O A group of living things with taxonomically similar traits. O A group of taxonomically similar living things in which all healthy members can interbreed and produce fertile offspring. QUESTION 8 If microevolution is any change in the gene pool of a breeding population, then macroevolution is: O A change in the genetic makeup of group that eventually results in the development of a new species. O The mass exctinction of old species to make way for new. O Changes in the physical environment at large. O When microevolution happens on a large scale. * QUESTION 9 What is the primary cause of speciation? O Extinction. O Overpopulation. O Environmental change. O When a breeding population becomes reproductively isolated from its ancestral population, for a long enough time, in a different enough environment, that it…The biological species concept is based on the assumption that species are reproductively isolated and do not share genes. And yet a number of organisms that are considered different species hybridize (mate and exchange genes). Hybridization between different species is more common in plants than in animals. Propose some possible reasons for this difference.Compare and contrast the neutral theory of evolution and the Darwinian (i.e., selectionist) theory of evolution. Explain why the neutral theory of evolution is sometimes called non-Darwinian evolution.
- Genetic variation is the product of completely random events, but acting upon this randomness is a very nonrandom process called natural selection.
