The theory of evolution states: A. better-adapted organism reproduces at a higher rate. How are these two copies similar? Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring. The most common mechanism for this is natural selection, in which individuals with beneficial heritable traits reproduce more than organisms without these traits, causing an increase in the frequency of the trait within the population. From one ancestral species that colonized the remote island chain, many new finch species evolved with differently sized and shaped beaks to exploit the foods available.

To know more check the How is this best explained?Ducks with less webbing worked harder than ducks with more webbing to eat aquatic plants. Finally, discover cousin species like Homo neanderthalensis. How can this population be expected to change over several successive generations, if the relative fitness differences observed remain unchanged? The longer that two populations are kept from interbreeding, the: a. more recessive alleles will be expressed.

Our experts can answer your tough homework and study questions. a. Could you please spare some time meaning? The three conditions that must be met for evolution to occur by natural selection are that there must be variation, there must be selection, and there must be inheritance of variation. Explain. Which is important for evolutionary change and why? A surprisingly small population could save our species. 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. By the year 2000, the graph shows the population of light colored moths significantly increasing. This is where terms like 'heterozygous' come into play. The descendants would look the same as the original individuals because species do not change. Therefore, the first concept of the term "species" was based on the morphology.

This is because the mutation would be passed down to future generations, and over time, the appearance of the species would change. Why do different genders of the same animal evolve differently? The male finches are the same shape and size but wear different combinations of about five colors. Human childhood is much longer than that of other animals; therefore, other animals rely only on their genetic information. There are at least 4 different ways that humans have genetic variation, a.

Yes, some individuals can change a little and pass those changes on to their offspring. Some force other than environmental conditions must be acting upon the males to produce so many species. If humans evolved from a common ancestor we share with monkeys, why do we have such broad variations in physical features across our species (i.e. Could individuals of a species look different today than individuals of the same species did many generations ago? No, species do not change even after many generations, so individuals of the same species would not look different. Is it through mutation?
