Question

Describe the modern synthesis of evolution, and explain how it connects Darwinian evolution to molecular evolution.

Accepted Answer

Hello, everyone. Here's our next question. It says which of the following ideas make up the modern synthesis of evolution. So we think about synthesis, we're talking about putting ideas together, putting two things together. And each of our answer choices offers us to kind of fields put together. And we need to select the one that view that reflects modern theories of evolution. And that choice is going to be choice, the natural selection and population genetics because it's combined Darwin's theory of evolution by natural selection change occurring due to pressures from the environment, certain changes being deleterious or beneficial to the organism and modern understanding of genes being the means by which genetic information is passed on to offspring. Let's look at our other answer choices to understand why they're not correct. Choice. A says cell biology and sociology. Um Well, these two fields would not be a part of an understanding of evolution. Choice B is natural selection and Lamarque is um well, natural selection could be correct since it's part of Darwin's theory of evolution. Um But Lamarque is um is the theory that acquired traits can be passed on, obviously mostly discredited in the stand age. You could argue epigenetic is a field where traits acquired in an individual's life can be passed on to offspring. But in general, acquired traits are not passed on. You have inherited traits. So that's not a correct answer. And then finally, choice c gene flow and catastrophic ism. Well, gene flow is just the study of how genes move between populations from one population to another. And then catastrophe is um, is the theory that changes in the earth's crust result chiefly from are the result chiefly of sudden and violent events. Well, gene flow is a part of the study of population genetics and sudden and violent events happening in the earth's crust also affect evolution and that you might have die offs of large populations and new populations adapting to the new situation. But there are obviously not the overarching synthesis of theories of evolution. So that's not our answer choice either. So again, which of the following ideas makes up the modern synthesis of evolution choice d natural selection and population genetics. See you in the next video.
