Discussion Answer the following questions 1. In the dark forest, what change did you observe in the moth population by the end? 2. Why did this happen? 3. In the wild, would moth parents have offspring that are identical in color to them? 4. What does "survival of the fittest" mean? 5. How does an adaptation first happen? 6. How does a trait become more common in a population over time?

The pesticide DDT was widely used in the 1940s as a method of insect control. In the late 1950s the first DDT-resistant mosquitoes were discovered, and eventually DDT-resistant mosquitoes were found globally. When DDT is used now, the development of DDT resistance in mosquito populations occurs in months rather than years.Which of the following best explains the observations concerning DDT resistance in mosquitoes? * nd 2 school The proportion of DDT-resistant mosquitoes in a population remains constant due to the metabolic costs of DDT utilization DDT is a chemical signal that delays normal reproductive cycles in many mosquito populations. Natural selection favors DDT-resistant mosquitoes that are already present in a population when DDT exposure occurs. Competition for limited resources causes mosquitoes to migrate to geographical areas that have richer supplies of DDT. A population of 1.492 finches is introduced to a rainforest. Over the next year, the finches showa death rate of…
Which evolutionary mechanisms (natural selection, mutation, genetic drift, or gene flow) would you need to understand to predict the success of genetically modified mosquitoes to: 1. Drive the mosquito population to extinction? 2. Replace the mosquito population with genetically modified mosquitoes that can not transmit malaria?

Q3) Why can we say that variations in human skin color are the result of natural selection in different environments? Why can we say that less pigmented skin is a result of conflicting selective factors? Answer in details(300 word)

2020 Online Discussion B. Darwin's Theory Warm-Up Active Developing the Theory of Evolution WARM-UP What was Charles Darwin's contribution to the theory of evolution? O Charles Darwin was the first to express the belief that all living things are related. Charles Darwin believed that organisms had a goal to adapt and did so through the inheritance of acquired traits. Charles Darwin introduced the idea that organisms better adapted to their environment would tend to survive, reproduce, and increase in number. Charles Darwin developed the theory of population growth. DONE O Intro Activity DII 96 2, or go
