2. You are asked to go on an expedition to Brazil to study the flora and fauna of the Amazon rainforest. In particular, you are interested in the Cordoncillo, a medicinal plant with anesthetic properties. You find a grove of 3000 Cordoncillo plants that appear to be identical to one another (phenotypic clones). The isolated grove spans an area of 100 square meters. You take some representative samples from a few plants back to your well-equipped lab and sequence their genomes. You conclude that the Cordoncillo plants in this grove are genetic clones (i.e. genetically identical). Based on this information, state whether the statements below are true or false. [10 pts total] 2a. True or False: This population can evolve by natural selection. [2 pts] 2b. True or False: This population can evolve by genetic drift. [2 pts] 2c. Provide an explanation for your answers above. [6 pts]
Answer. True this population evolve by natural selection because they might get separated from one place to another so accordingly they natural selected them and survive in different conditions.
False it not a case of genetic drift because if there is any genetic drift then there should be genetic different but by sequence both share same genome. Which means they only selected by nature

You are an entomologist studying the population genetics of aphids. Aphids are insects that “suck” the phloem from plants. There is an aphid population on a milkweed plant outside your lab. You sample the aphid population, sequence their DNA and conclude that they are all genetic clones (i.e. genetically identical). This is possible because aphids parthenogenetically reproduce during the summer. Describe what would need to happen in order for this population to evolve. To earn full credit, you need to...
Can I get a summary of this article name "Evolution Is Happening Faster Than We Thought" By MENNO SCHILTHUIZEN? — A FRIEND recently invited me over to see the blackbird that had taken up residence in a potted plant on her balcony. Serenely incubating eggs in the inner city, this bird had little in common with its shy, reclusive ancestors that nested in Europe’s forests. Early in the 19th century, probably in Germany, blackbirds began settling in cities. By the...
