Species evolve over time through a process of natural selection. All species share a common ancestor. Variation exists within populations, leading to differential survival and reproduction. Evolution is driven by the accumulation of small, gradual changes over long periods of time.
The major concepts of the biological theory of evolution include natural selection (survival of the fittest), genetic variation, adaptation, and descent with modification (common ancestry). These concepts explain how species change over time through the process of evolution.
A major risk to a species that only reproduces by cloning is lack of genetic diversity. This can make the species more vulnerable to diseases, environmental changes, and other threats, as they lack the genetic variation that can help populations adapt and survive. Additionally, if a clone is susceptible to a specific threat, it can wipe out an entire clone-based population.
The two major objectives in anther culture are to promote cross-pollination and ensure the production of genetically diverse offspring. This helps increase genetic variation within the population, which can lead to improved adaptability and evolutionary success.
The five fingers of evolution refer to five major principles that explain how evolution works: genetic variation, competition for resources, natural selection, adaptation, and speciation. These concepts help us understand how species change and evolve over time in response to their environment.
Genetic mutations are the major cause of variation within species. Mutations can introduce new genetic traits that can be passed on to offspring, leading to diversity within a population. Other factors like genetic recombination, migration, and environmental influences can also contribute to variation within species.
All species have genetic variation. ;D

False. The loss of a species from an ecosystem can have cascading effects on other species and the overall balance of the ecosystem. Each species plays a specific role in the ecosystem, so the loss of one can disrupt the interconnected relationships within the system.
Their bodies aren't adapted to the new environment yet.
The major cause for seasonal temperature variation at any given latitude on Earth is the tilt of the Earth's axis relative to its orbit around the sun. This tilt causes different areas to receive varying amounts of sunlight throughout the year, leading to changes in temperature.
When alleles are recombined during sexual reproduction, they can produce dramatically different phenotypes. Thus, sexual reproduction is a major source of variation within many population.
Yes.

A species name may provide information on the scientific classification and relationship of an organism within the taxonomic hierarchy. It can also help in the identification and communication of a particular species, allowing scientists to have a standardized way of referring to and studying organisms.
