What Is Descent With Modification? Darwin defined evolution as “descent with modification,” the idea that species change over time, give rise to new species, and share a common ancestor. The mechanism that Darwin proposed for evolution is natural selection. Which best defines descent with modification? Descent with modification is simply passing traits from parent to
How Does Evolution Affect Everyday Life? One of the more important evolutionary concerns facing humans today is the continual evolution of antibiotic-resistance in bacteria. … Similarly, the use of pesticides in agriculture has driven the evolution of resistant insects, requiring the use of harsher chemicals in greater quantity to kill them. How is evolution relevant
How Does Evolution By Natural Selection Explain Both The Unity And Diversity Of Life On Earth? Evolution is considered a unifying theory of biology. It explains the unity and diversity of life. 1)Descents from a common ancestor explain the unity of life. 2) the unity of life = living things share a common chemistry and
What Are The Four Conditions Of Natural Selection? Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results. What are the 4 main points of natural selection? Variation. Organisms (within populations) exhibit

Individuals in a species show variation in physical characteristics. … As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve. What are the 4 main points of
What Are Some Disadvantages Of Selective Breeding? It may lead to a lack of variety in plant or animal species. … Genetic mutations are still going to occur. … The process of selective breeding becomes about humans only. … There is no guarantee that the desired traits will pass to the offspring. … It can
How Does Environment Affect Natural Selection? Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time. Natural selection is one of the ways to account for the millions of species that have lived
What Does Spencer Mean By Survival Of The Fittest?
