What is balancing selection and how does it contribute to genetic diversity in biology?
Balancing selection is a type of natural selection that maintains genetic diversity by preserving different versions of a gene in a population. This occurs when multiple versions of a gene are advantageous in different environments or circumstances, preventing any one version from becoming fixed in the population. As a result, genetic diversity is maintained, allowing for adaptation to changing conditions and increasing the overall fitness of the population.

How does artificial selection in biology impact the genetic diversity of a population?
Artificial selection in biology can impact the genetic diversity of a population by favoring certain traits or characteristics in organisms, leading to the breeding of individuals with those desired traits. Over time, this can reduce the overall genetic diversity within the population as only specific traits are being selected for, potentially leading to a decrease in genetic variation.
Why is crossing over important in biology and how does it contribute to genetic diversity?
Crossing over is important in biology because it allows for the exchange of genetic material between homologous chromosomes during meiosis. This process results in new combinations of genes being passed on to offspring, increasing genetic diversity within a population.
What is natural selection sometimes referred to as in the field of biology?
Natural selection is sometimes referred to as "survival of the fittest" in the field of biology.
What is divergent evolution and how does it contribute to the diversity of species in biology?
Divergent evolution is when two or more related species evolve different traits over time. This process leads to the creation of new species with unique characteristics, increasing biodiversity in biology.
Can you define homoplastic traits and explain how they contribute to evolutionary biology?
Homoplastic traits are similar characteristics found in different species that did not arise from a common ancestor. These traits can provide insights into convergent evolution, where unrelated species develop similar adaptations to their environment. By studying homoplastic traits, scientists can better understand how natural selection shapes the diversity of life on Earth.
The unifying theme in biology responsible for species diversity is?
The unifying theme in biology responsible for species diversity is evolution through natural selection. This process drives genetic changes over time, leading to the adaptation of organisms to their environment and the emergence of new species.

1. Plant 2. Animal
What is the importance of competition in biology?
Competition in biology is important as it drives natural selection, leading to the survival of the fittest. It helps maintain species diversity and ecosystem balance by controlling population sizes. Competition also fosters adaptation and evolution by selecting for traits that provide a competitive advantage.

What is meant by evolution in biology and how does it shape the diversity of life on Earth?
Evolution in biology refers to the process by which living organisms change and adapt over time through genetic variations and natural selection. This process leads to the diversity of life on Earth as different species evolve to better survive and reproduce in their environments. Over millions of years, these changes accumulate, resulting in the wide array of species we see today.
What is the act of protecting ecosystem diversity?

What did Charles Darwin contribute to science?
Charles Darwin proposed the Theory of Evolution or Natural Selection. The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring.
