What is a sentence with the word biological evolution?
>The structural and well-organised gradual process of change means 'biological evolution'. >Variation and heridity are two basic factors of evolution. >In long term.evolution leads to existence of new species which have different characteristics than their ancestors.
What is a process through which new species can arise?
Natural selection that leads to a great enough change in allele frequency over time in a population of organisms, evolution, and helped by environmental changes to create sub-populations of these organisms that can no longer breed among themselves and then are accounted new species.
What way leads to competition between two species?
An overlap in their niches
What leads to competiton between two species?
Anything and Everything!
Why crossing over occurs?
Usually,crossing over occurs to create new species of life.In the case of chromosomes,2 non sister chromatids link up at chiasmata and crossover.Crossing over usually leads to evolution of new species.
What does Natural selection leads to the evolution of?
A new and better adapted species.
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.

The model of evolution in which gradual change leads to species formation over time is called?
gradualism
What are the implications of asexual reproduction in the evolution of species?

Define the biological process of evolution?
Biological evolution is the change of animal and plant life over time. Biological evolution is used to explain changes in finch beaks for example.
Difference between the evolution of man and the evolution of apes?
Man is an ape. The evolution of one is the evolution of the other. Genetics in a particular immediate environment and reproductive isolation leads to the variences in two species that share very recent common ancestors.
What are the three measures to life's variations?
Adaptation: The ability to adjust to changing environmental conditions. Diversity: The range of different species and genetic variations within an ecosystem. Evolution: The process of natural selection and genetic change over time that leads to species' adaptation to their environment.
Explain how a species can change over time?
Through mutations in DNA. If a mutation is beneficial and helps the organism survive it is passed on to the next generation which leads to the evolution of a species causing it to change.
What did Darwin's theory of evolution suggest?
Darwin's theory of evolution suggested that species evolve over time through a process called natural selection, where organisms with favorable traits are more likely to survive and reproduce. This process leads to the gradual change and adaptation of species to their environment.
How cross pollination leads to evolution?
Cross-pollination, the transfer of pollen between different plants, can lead to evolution by introducing new genetic variations into a population. This mixing of genetic material increases genetic diversity, which then provides a wider range of traits for natural selection to act upon. Over time, this process can drive the adaptation of species to their environment and lead to the formation of new species.
How can a population guarantee reproductive success in an ever-changing environment?
It can't and species die out because of this all the time. However variation in the gene pool will throw up variations in the population which, as the environment changes, leads to the evolution of new species.
