For the GEN data set, the genetic distances ΔGEO(X, Y) between two individuals with known latitude and longitude were calculated using the Haversine formula47: , where R is the radius of Earth (for simplicity assumed to be equal to 3,959 miles), δlat=lat2−lat1, and δlon=lon2...
Verena Harms3, Anne Jarausch3, Ilka Reinhardt4, Gesa Kluth4, Heribert Hofer1 & Oliver Krone1 The recent recolonisation of the Central European lowland (CEL) by the grey wolf (Canis lupus) provides an excellent opportunity to study the effect of founder events on endoparasite ...
Determining the size and orbital distribution of the population of near-Earth asteroids (NEAs) is the focus of intense research, with the most recent models converging to a population of approximately 1000 NEAs larger than 1km and up to approximately 10 9 NEAs with absolute magnitude H < 30....

aIt has been estimated that a thousand years ago there were less than 400 million people on earth.Today ,however,the world's population has amounted to more than 10000 million.What a big proplem! If it keeps growing at a surprising speed,there will be many proplems of the earth.Populatio...
Was it due to a meteor slamming into Earth near the coast of modern-day Mexico, or was it from some long-term weather cycle that is not yet understood? One hypothesis that will never be proposed is that humans had something to do with it. Mammals were small, insignificant creatures of ...
Humans had been around for tens of thousands of years by the year 1 A.D. when the Earth's population was an estimated 200 million, notes Worldometers. It hit the billion mark in 1804 and doubled by 1930. It doubled again in less than 50 years to four billion in 1974. ...
