and Terms of Use. Of course one might ask what difference it makes if a species of frog dies out? The Earth is currently losing biological diversity at an ever increasing rate, and according to Jacob Höglund it is clear that this is the result of human activity.

Question: Why is genetic variation important? Think back to our example of the violet. For as long as the Earth has existed, the number of species and the biologically diversity present have gradually increased. We want to avoid emergency conservation—expensive efforts to save species at the last minute.'. Just having people on Earth is not sufficient.

Reporting on the BBC on molar agenesis in modern humans? I cant remember the year, but sometime in the late 1900s an unknown disease was killing hundreds of thousands of people in the US, and was spreading like wildfire. Thank you for taking your time to send in your valued opinion to Science X editors. One of the group's current studies relates to investigating whether the dreaded fungal disease Batrachochytrium, which has caused mass mortality of amphibians in other parts of the world, has gained a foothold among Swedish frogs and toads and how sensitive they are to the disease. For example, genetic variation disappears more quickly in wolves, where there are not many individuals, than in herring, where there are very many individuals.

By studying mammal fossils, the speed at which species 'normally' die out has been established. Some combinations of alleles create phenotypes that provide a survival advantage for the individual. Jacob Höglund says that we must try to understand how we can co-exist with other organisms. Furthermore, genes code for a plethora of traits within an organism -from hair and eye color, to blood type and cell metabolism. 1. Genetic variation is very important in the genetic code because we and all animals would be incredibly susceptible to genetic diseases if it wasn't varied. The drift varies in strength depending on how large the population is. A: Introduction  Questions are typically answered within 1 hour.*.
