are there more people alive now on earth than have died throughout human history?

According to the Population Reference Bureau, the estimated population of Homo Sapiens that has ever been born on Earth up until the year 2002 is 106,456,367,669.  \n\nThe population in the year 2002 was 6,215,000,000.  \n\nTherefore the percent of people living now compared to all that have lived is roughly 6%.  Quite high if you think about it.

It is very questionable that humans are evolving, at least in terms of largescale selections.  Where we are today with technology, rather than nature selecting the most fit of us, oftentimes we alter nature to allow everyone to live.  This obviously isnt true in all cases, but we are at least tampering and slowing down human evolution

Tough one, but here it is according to the World fact Book 2005\n4 births each second of every day   almost 2 people die each second

I think there is definitely other forms of life. Whether there human or not don't know. Since humans haven't been around nearly as long as the planets, stars, galaxies etc. I would bet that there are far more intelligent life forms out there.

Around 7 billion and growing rapidly, unevenly in the different regions of Earth. It is expected that by the half of this century that number will double.... just imagine what we`ll do with the forest and wild life and the balance on the planet, carbon emissions....

This is about as good as it has ever been for our species. Unfortunately, war is more common than peace throughout history. Currently, there are more people with basic human rights and freedoms than ever before. With that said, only seven countries on Earth haven't had to change their borders because of warfare or revolution within the last hundred years. Given a few more centuries, maybe we humans will begin to get our act together.

.World population\n\nMap of countries by population —showing the population of the People's Republic of China and India, the only two countries to have a population greater than a billion. (See List of countries by population.)\nThe world population is the total number of humans alive on the planet Earth at a given time. As of late 2006, the world population reached 6.5 billion.[1] In line with population projections, this figure continues to grow at rates that were unprecedented prior to the 20th century.

I think that such numbers do not exist even for animals, which surround us now. Because full mortality data are needed, date of birth and date of death of every individual.\n\nMost literature indicate only maximal life span (humans 122) for animals: elephants about 78, penguins about 20, musk-ox about 24, some whales more than 200 years.\n\nI guess, mamoths lived about 40 years in average, but maximum age could be 90 years.

Already, more than twenty-five million people around the world have died of AIDS-related diseases. In 2005, around 3.1 million men, women and children lost their lives. Nearly twice the number who have died until now - 40.3 million - are now living with HIV, and most of these are likely to die over the next decade or so. The most recent UNAIDS/WHO estimates show that, in 2005 alone, 4.9 million people were newly infected with HIV.

Depends where you look. We don't have records long enough to look at the statistics of earthwuakes for the whole of the Earth.\n\nHowever, over time, some areas become more active and some less so.

I DONT THINK THAT WE R  ALONE . WE HAVE SEEN A FEW SIGNS OF XTRA TERRESTRIAL LIFE AND IT  IS POSSIBLE THAT THERE ARE OTHER LIVING ORGANISMS INHABITED PLANETS

Current population of the World 6,490,909,958.\n\nThis is as of 5 27AM eastern time.  \n\nBut there is only a correct answer for a certain amount of time as someone is born every second.  Also you have to factor in whether or not there is an extraterrestrial existence.

There are over two million species alive on earth right now. Which particular path do you want?\n\nFor humans, we know the progression through some crucial stages, but not the whole thing. For example, we have very good fossils for the transition between certain fish and amphibians, between reptiles and mammals, very good evidence for the last couple of million years. The early development of primates is being actively researched with a lot of interesting results.\n\nHere is the basic progression:\nLife started about 3.8 billion years ago\nEucaryotic life (with true nuclei) started about 2 billion years ago.\nMulti-cellular life started about 570 million years ago.\nThe first vertebrates were around 450 million years ago.\nThe developement of sarcopterygian fish was about 400 million years ago.\nDevelopment of labrynthodont amphibians from the sarcopterygian fish was about 360 million years ago. \nFirst reptiles from amphibians was about 320 million years ago.\nA wide variety of mammal-like reptiles developed in the time period between about 300 million years ago and 250 million years ago, with the cynodonts developing later. \nSmall, rodent-like mammsls developed from the cynodonts about 220 million years ago.\nSome very early primates developed around 60 million years ago from smallish rodent-like mammals.\nHomonoidae (apes) developed around 22 million years ago with Proconsul the type species.\nDryopithecus was around 17 million years ago in Africa and was an ancestor to most african apes.\nAustralopithecus developed about 4 million years ago in Eastern africa with Australopithecus afarensis the most likely human ancestor.\nBetween about 2 and 3 million years ago there were several hominid species in eastern and southern africa. The exact human ancestor is controversial since they are so similar.\nHomo habilus appeared about 2 million years ago and was replaced by Homoe erectus about 1.5 million years ago.\nHomo sapiens (modern humans) appeared about 300 thousand years ago in africa. There were other hominid species around at that time and later. For example Homo neanderthalensis was around until about 25 thousand years ago. Whether Neanderthals contributed to modern humans is another controverisal question.\n\nIt should be pointed out that the exact ancestral species may not be known. But it is typical for a variety of closely related species to develop in the fossil record at the same time. Figuring out which one is the actual ancestor for a given later species is not always possible given the fragmentary fossils available and our current knowledge of how structural changes occur in evolution.\nI hope this helps.

Evolution isn't something that happens instantly, it is a slow process that takes a long time. Humans actually have only been around for a few thousand years and "civilized" humans have only been around for 10,000 years. In fact, hominids (upright walking apes that are all extinct except for humans) have only been around for less than 2 million years. We are evolving slowly but by the time we radically change, we will not notice because the change would have been very very slow.

Everything today survives.\nAnd that is not the way nature intended it to be.\nWe keep sick people alive who normally wouldn't make it.\nWe keep children alive who would have died at birth and now are living breathing little vegetables.\nAnd that is supposed to be progress?\n\nOk,  I stop now.  I think you were looking for somewhat a different answer....smile

The world population is the total number of humans alive on the planet Earth at a given time. According to estimates published by the United States Census Bureau, the world population in June 2005 was ~6,450,000,000<ref>On January 3, 2006, the population counter read: "World 6,489,102,362 : 13:39 GMT (EST+5) Jan 03, 2006" United States Census Bureau</ref>. In line with population projections, this figure continues to grow at rates that are unprecedented prior to the 20th century. Approximately one fifth of all humans that have existed in the last six thousand years are currently alive. By some estimates, there are now one billion (thousand million) young people in the world between the ages of 15 and 24.
