The answer to this question is not well understood, but it is thought that a number of things would need to happen in order for one species to change into two species over time. Submit your documents and get free Plagiarism report, (Rate this solution on a scale of 1-5 below). Second, the two species would need to have a significant difference in their reproductive capabilities.

Many generations later, almost all ducks had more webbing on their feet. a) Yes, all individuals can change a little and pass those changes on to their offspring. Explain. Species have changed and continue to change over time because of their environment, genetics, and reproduction. Near industrialized areas, black powder covered surfaces, including the moth habitat. Q6.5. And instead of requiring large changes to the DNA to govern color production over many parts of the birds body, it has been accomplished through just a few changes to regulatory regions of the genome. Which of the following is not part of how we define a species? All living species de. Scientists look for those rare instances when a species suddenly diverges, or radiates into multiple forms, each with a different appearance or behavior. Pellentesque dapibus efficitur laoreet.

No other species has ever wielded such power, and no species could. A species is a population of plants or animals that can breed to produce offspring that can then produce offspring themselves. To put this another way: all humans have the same genes, yet we do not look alike. a) Variation b) Normalization c) Extinction. Why or why not? a) Yes, all individuals can change a little and pass those changes on to their offspring. could individuals of a species look different today. You can specify conditions of storing and accessing cookies in your browser. There is similar variety for wings and head color, creating an almost mix-and-match effect when the species are viewed side by side. Unlike Darwins finches, in which environmental conditions such as food supply rewarded birds with different beak shapes, the capuchino finches all eat the same type of food and live in grasslands scattered across South America. a. Learn about Charles Darwin's background, what theory he is known for, and what natural selection is. D) amino acids Exposure to DDT caused specific, nonrandom mutations for DDT resistance within the population. Because so much of each species genome is the same, Campagna says its easier to find the minute differences, making them great subjects for study. Question Could individuals of a species look different today than individuals : 425869. O No, species do not change even after many generations, so individuals of the How are the striking similarities among genes that govern development in widely differing species strong evidence for evolution? Could individuals of a species look different today than individuals of the same species did many generations ago? The central ideas of evolution are that life has changed over time and different species share common ancestors. This is because the different environments would cause different changes in the fish's appearance. Now, it doesn't reach the same kind of headlines because there's many different infections and different parts of the body and different bacteria. See Answer Why do humans, animals, and plants have to evolve reproductive function? Morphology is how an individual looks. A 50.0 mL sample of drinking water was found to contain 1.25 \mug of arsenic. If monkeys and humans evolved from a common ancestor, why did we evolve differently? A million years ago, there were probably a few different species of humans around, including Homo heidelbergensi s, which shared similarities with both Homo erectus and modern humans, but more primitive anatomy than the later Neanderthal. . Why or why not? Which of the following is REQUIRED for the process of natural selection to occur? Why do humans share lots of DNA with both rats and bananas when each of these are very different things? Which of the following is REQUIRED for the process of evolution by natural selection to occur?Offspring must be similar to their parents due to share genes.There must be a sudden environmental change.There must be a predator preying on the species.One or more species must have recently been introduced to the region.Q6.7. Difficulties with Darwin's concept tempted a number of people to try to redefine species by means of interbreeding. Explain. 1. C) not all mutations cause visible change. Explain why monotremes are unique mammals. All other trademarks and copyrights are the property of their respective owners. Yes, when the environment changes, individuals with certain inherited traits survive and will be able to reproduce. Get access to this video and our entire Q&A library, Human Evolution Lesson for Kids: Timeline & Stages. b) Yes, some individuals can change a little and pass those changes on to their offspring. Lovette. Most people today would classify such forms as different species, and none of these sibling species mate with one another in normal circumstances. A head of broccoli today is not the same as a head of broccoli 70 years agothey're almost different species. In biology, what is an adaptation? Right now, theyre considered separate species because the color and song of males keep them from widely interbreeding. Could individuals of a species look different today chegg? Reduction of the burning of fossil fuels (coal). A few mosquitoes in the population were resistant to DDT before it was ever used. c. natural selection. The billions of human beings living today all belong to one species: Homo sapiens. In what ways is culture similar between human and nonhuman primates? What is the most likely explanation of why this antibiotic no longer kills this bacteria? Why is genetic variation within a species important to conservation? Pellentesque dapibus efficitur laoreet. How can making good decisions help people? What are the general characteristics shared by all animals? Humans all share the same cultural knowledge and beliefs. Was the final answer of the question wrong? Does genetic variation makes evolution possible? The 14 species of finches on the Galapagos Islands evolved from a single species that migrated to the islands several million years ago. If you're looking for the answer to the question: Could individuals of a species look different today chegg? 11 months ago, Posted b. Q6.5. Consider a population that lacks variation and no individual has any advantageous traits. a. Wing bone structures of penguins and other birds are functionally different, but homologous. For example, if one individual of a species had a mutation that caused them to have red eyes, while the other individuals of the species had the normal allele for eye color, the individual with the mutation would stand out.
