Why do human bodies look so different across the planet? D) amino acids What caused us to become so different? What is the reason for the phenotypic differences between individuals of the same species? 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. However, only around 1.2 million species have been identified and described so far, most of which are insects. All of the following are protective adaptations except one. The most well-known example is a group of more than a dozen finch species in the Galapagos. O Yes, some individuals can change a little and pass those changes on to their offspring.

According to the diagram, which of the following statements is true? Why are there so many species of monkeys but only one species of human? The outcome of each genetic bird recipe is a capuchino finch that looks differentone species with a black throat and gray cap, another with a white throat and gray cap. Are humans subject to the same pressures of natural selection as other organisms? During the Industrial Revolution through the mid-20th century, factories and power plants, which burned coal, produced large quantities of soot and smog. This can result from random processes called genetic drift, or a more adaptive mechanism called natural selection. Explain why only populations evolve but individuals do not.

They were more muscular than we were and they had bigger brains than we did (or do today). There is similar variety for wings and head color, creating an almost mix-and-match effect when the species are viewed side by side. This is where terms like 'heterozygous' come into play. If you're looking for the answer to the question: Could individuals of a species look different today chegg? Traits must be inherited from one generation to the next. \\ d.
