Could individuals of a species look different today chegg?

Looking for an answer to the question: Could individuals of a species look different today chegg? On this page, we have gathered for you the most accurate and comprehensive information that will fully answer the question: Could individuals of a species look different today chegg?

After being isolated for thousands of years, the two populations meet up again after glaciers retreat at the end of the ice age, but the members of the two populations can no longer interbreed. Nice work! You just studied 35 terms! Now up your study game with Learn mode.


In some cases, it may be difficult to predict whether incipient species will continue to diverge. c. Biological diversity does not vary in a smooth, incremental way. d. Hybrid zones may form if reproductive isolation is incomplete. e. A single lineage may evolve over time without giving rise to a new species.


None of the above; it does not represent a challenge. Even trained biologists have difficulty telling females of Drosophila melanogaster and D. sechellia apart, and yet these species are reproductively isolated. Thus, these species are considered _______ species. d. Coyne's


Ginkgo trees grow in Asia and North America and thus are divided into two groups that are geographically separated. Mayr's framing of the biological species concept would classify these populations as belonging to the same species because they a. are reproductively isolated. b. are potentially capable of exchanging genes.

Which of the following are requirements of evolution by 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.


Which of the following is required for the process of natural selection to occur chegg?

Question: which of the following is required for the process of natural selection to occur offspring must be similar to their parents due to shared 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.


How species have changed and continue to change over time?

a) Species change over time; some traits become more common, others less. This process of change is driven by natural selection. The process described in a) continues to the point where descendants eventually constitute a different species from their remote ancestors. ...


How can closely related species look different?

Some organisms may be very closely related, even though a minor genetic change caused a major morphological difference to make them look quite different. ... This usually happens because both organisms developed common adaptations that evolved within similar environmental conditions.


What is a species chegg?

Species Definition A group of organisms sharing a similar genetic heritage who can breed to produce fertile offsprings are known as species.


What are the three conditions that must be met for evolution to occur by natural selection?

The essence of Darwin's theory is that natural selection will occur if three conditions are met. These conditions, highlighted in bold above, are a struggle for existence, variation and inheritance. These are said to be the necessary and sufficient conditions for natural selection to occur.


Which factors could be important for a species to evolve by 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.


Which two factors could lead to the evolution of a species over time?

Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the ...


Why do different species look different?

Species, which are made of many individuals, don't pass from one state to the next in immediate changes. Differences in appearance evolve gradually through time, as do changes in the window of recognition.


Do individuals adapt or does the population adapt?

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. ... Over time, these advantageous traits become more common in the population.


Could individuals of a species look different today than individuals?

Could individuals of a species look different today than individuals of the same species looked many generations ago? ... Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring.


What are the 3 conditions for natural selection?

Conditions for natural selectionReproduction. Entities must reproduce to form a new generation.Heredity. ... Variation in characteristics of the members of the population.Variation in the fitness of organisms associated with these characteristics.


What are some examples of environmental changes that could create selection pressures for a species?

Predation, competition and disease are examples of selection pressures.


What makes a species different from other species?

Most evolutionary biologists distinguish one species from another based on reproductivity: members of different species either won't or can't mate with one another, or, if they do, the resulting offspring are often sterile, unviable, or suffer some other sort of reduced fitness.


Do individuals evolve?

How do organisms evolve? Individual organisms don't evolve. ... These individuals generally survive and produce more offspring, thus passing their advantageous traits on to the next generation. Over time, the population changes.


What would not cause one species to change into two species over time?

One species does not "turn into" another or several other species -- not in an instant, anyway. The evolutionary process of speciation is how one population of a species changes over time to the point where that population is distinct and can no longer interbreed with the "parent" population.


Which factors could affect whether a species evolves?

Evolution is a consequence of the interaction of four factors: (1) the potential for a species to increase in number, (2) the genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for an environment's limited supply of the resources that individuals need in order to ...


Can organisms or species choose to evolve?

Individual organisms don't evolve. Populations evolve. Because individuals in a population vary, some in the population are better able to survive and reproduce given a particular set of environmental conditions.


How can a species evolve through natural selection?

Natural selection is a mechanism of evolution. 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.


Which of the following is required for natural selection to occur in a population?

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.
