Evolution River

canada goose outlet sale A discovery in an ancient river demands a re think of the time frame of human evolution. canada goose outlet sale

canada goose outlet toronto Astounding work done by two New Zealand scientists is set to rock the world of evolutionary biology. For buy canada goose jacket cheap years, we’ve assumed canada goose coats that the rate of evolution canada goose store which is determined by changes in our DNA came about very slowly. However, an Otago University study suggests that canada goose uk black friday the pace of evolutionary change may be happening ten times faster than we previously thought. canada goose outlet toronto

canada goose outlet online uk Evidence of this radical discovery has been found in New Zealand’s Marlborough Sounds. Here it was discovered that an ancient river had separated into buy canada goose jacket two, thereby separating the fish uk canada goose outlet population and allowing scientists a unique opportunity to measure the pace of DNA change. canada goose outlet online uk

canada goose outlet toronto location One that’s set to canada goose clearance sale rock our understanding of evolution. canada goose outlet toronto location

canada goose outlet vip Scientists in New Zealand have unearthed clues uk canada goose revealing our DNA is changing at a rate faster than we first thought much Canada Goose Coats On Sale faster. canada goose outlet vip

canada goose outlet toronto address Dr Canada Goose Outlet Chris Burridge: We’re thinking about how long ago things happened in the past and also the rate of DNA change which underlies all evolution. canada goose outlet toronto address

canada goose outlet hong kong Narration: Zoologists Jon Waters and Chris Burridge, and geologist Dave Craw made this incredible discovery after months of detective work cheap canada goose uk here in the Marlborough Sounds in New Zealand’s South Island. canada goose outlet hong kong

canada goose outlet edmonton Dr Jon Waters: To find that the rate that people have been using is wrong, really has some significant Canada Goose Jackets changes for the way we understand evolutionary history for Canada Goose online a whole bunch of species, maybe even including humans. canada goose outlet edmonton

canada goose outlet los angeles Narration: Since the late 70’s, we’ve assumed that our DNA changes, or mutates, at a rate of around 1 to 2 per cent every million years. canada goose outlet los angeles

canada goose outlet location DNA of most canada goose coats on sale animals, whether it’s from humans, birds or fish, mutates at approximately this rate. And without mutation, living organisms would not evolve. canada goose outlet location

canada goose clothing uk Dr Chris Burridge: canada goose uk shop The changes in DNA that are out there in the population right now, they’re basically the building blocks for future evolution. canada goose clothing uk

canada goose outlet usa Narration: Knowing what this rate is is vastly important in understanding our past. canada goose outlet usa

canada goose outlet mississauga Dr Jon Waters: People have really been using DNA as one of the prime techniques to put a canada goose black friday sale time scale on evolutionary history. canada goose outlet mississauga

canada goose outlet houston Narration: For instance, we’ve used the rate of DNA mutation to determine when humans moved out of Africa. canada goose outlet houston

canada goose outlet england But we can’t categorically say that the rate of change we’ve been using to work out these dates is correct. You calculate the rate of DNA change by dividing genetic difference by time. Let’s say that difference is 1 percent. Canada Goose Online You then divide that difference by the amount of time that’s passed since they were the same fish. This means the rate of canada goose clearance DNA change is 1 per cent per million years. canada goose outlet england

canada goose outlet online store canada goose sale The problem is that it’s extremely difficult to work out exactly how long ago that one species became two new species. canada goose outlet online store

canada goose outlet in canada Dr Jon Waters: Basically people have been forced to rely on fossils, which I think are not the best sort of evidence for Canada Goose Parka this question that we’re looking at. They canada goose uk outlet have a fairly incomplete sort of record. canada goose outlet in canada

canada goose premium outlet Narration: So, Jon and Dave set out to calibrate the Canada Goose sale molecular clock. This led them to the valleys and rivers of the Marlborough Sounds. canada goose premium outlet

canada goose outlet mall Within this vast array of rivers, they were looking for evidence of an ancient river that had split into two separate rivers. The Marlborough region is ideal for finding this sort of geological event. canada goose outlet mall

canada goose outlet store montreal Associate Professor Dave Craw: This is where the geological things are happening quite fast, very quickly in relation to other parts of the world. canada goose outlet store montreal

canada goose outlet ontario Narration: This kind of event is very useful because canadian goose jacket when a river splits in two its fish canada goose population is also divided in two. canada goose outlet ontario

canada goose outlet las vegas Dr Jon Waters: If you get one river suddenly being cut off from another part of a river, then you get genetic changes occurring between those now isolated populations. canada goose outlet las vegas

canada goose outlet in vancouver Narration: If cheap Canada Goose they could figure out exactly when the ancient river had canada goose factory sale split, they’d know how long the fish had been separated, and could more accurately calculate the rate of canadagooseonline.info DNA mutation. Dave set out looking for signs of what the rivers were doing thousands of years ago. canada goose outlet in vancouver

canada goose outlet factory He focused his attention on two rivers, separated by low lying hills. And he found a very significant clue in this river here canada goose outlet factory.
