You look at the fact that for millions of years species on earth have been developing and we've been knocking them off at like a hundred a day.

We are in grave danger of losing forever not just millions of years of evolution on earth, but the eons of change that have produced man and his natural environment.
More and more of us live segmented, compartmentalized lives. This isn't natural. For millions of years, our forebears knew everyone around them and everyone knew them.
Sometime during the many millions of years that have elapsed since mammalian faunas came into existence, some sort of island crossed from West Africa to South America.

As social animals, we need to exchange juicy tales about someone - to connect with one another. For millions of years our forebears must have sat around the campfire, whispering about everyone they knew.

Human beings and plants have co-evolved for millions of years, so it makes perfect sense that our complex bodies would be adapted to absorb needed, beneficial compounds from complex plants and ignore the rest.
Men are weak now, and yet they transform the Earth's surface. In millions of years, their might will increase to the extent that they will change the surface of the Earth, its oceans, the atmosphere, and themselves.

Each creature both great and small has evolved after millions of years of evolution serving an integrated and important part in the ecological balance of our Earth. Upset the balance and the consequences are disastrous.

The one process now going on that will take millions of years to correct is the loss of genetic and species diversity by the destruction of natural habitats. This is the folly our descendants are least likely to forgive us.
Mythology is something that always has opportunities to explore. 'It' has been on Earth for millions of years. He's been in contact with humans for hundreds of years, every 27 years. So you can imagine the amount of material.
Women are very attracted to a low voice because it's linked to testosterone, which for millions of years was a sign that men had very good spacial skills and would have been very good at hunting and finding their way back home.

The urgency to mate persists in all people as in all other mammals because of the evolutionary drive to continue the species, the inborn imperative for genes to reproduce and hormonal differences that evolved over millions of years.
When you fall into a black hole, everything that falls in after you over millions of years, as seen by you inside the black hole, comes pounding down on you in a fraction of a second, because of the enormous differences of time flow.
We've evolved over millions of years to sense the world around us. We use our five natural senses to perceive information. But the huge amount of information mankind has accumulated and stored online cannot be perceived by these senses.
We're going to lose more species, acidify the oceans more, do damage that it will take millions of years - if not longer - to unwind. Exactly how much damage will we do? How deep will those scars run? We don't know yet. But we will turn the ship.
We've only explored about 5% of our ocean. There are great discoveries yet to be made down there - fantastic creatures representing millions of years of evolution and possibly bioactive compounds that could benefit us in ways we can't even imagine.
The time necessary for the disappearance of half the atoms, called the half-life, is a fundamental characteristic of each radio-element; according to the substance, the value of the half-life varies between a fraction of a second and millions of years.
For some, the belief in a Young Earth seems to be based on a kind of intuition or faith in what they believe an omnipotent God should do. It reasons that if God is all powerful, then certainly He would not have taken millions of years to make the earth.

Planting native species in our gardens and communities is increasingly important, because indigenous insects, birds and wildlife rely on them. Over thousands, and sometimes millions, of years they have co-evolved to live in local climate and soil conditions.
We're addicted to this concept of civilization - we can't imagine living outside of it because we've had it for 10,000 years, all of what we call history. But according to archaeologists, humanity has been on this planet for millions of years in indigenous form.
We've only explored about five percent of our ocean. There are great discoveries yet to be made down there, fantastic creatures representing millions of years of evolution and possibly bioactive compounds that could benefit us in ways that we can't even yet imagine.
There are so many ways to characterize evolutionary success. If one criterion is the number of millions of years that the species persists, we're still just infants. We're way too young of a species to tell if we were a creative fluke or if we have any staying power.
Civilisations have been destroyed many times, and this civilisation is no different. It can be destroyed. We can think of time in terms of millions of years and life will resume little by little. The cosmos operates for us very urgently, but geological time is different.
The stars look the same from night to night. Nebulae and galaxies are dully immutable, maintaining the same overall appearance for thousands or millions of years. Indeed, only the sun, moon and planets - together with the occasional comet, asteroid or meteor - seem dynamic.
Yucca Mountain isn't pretty. And it also isn't large. From far away, the mountain's just a squat bulge in the middle of the desert, essentially just debris from a bigger, stronger mountain that erupted millions of years ago and hurled its broken pieces into piles across the earth.
Mothers really were not built to raise babies not only by themselves, but with only a partner. For millions of years, a woman had much more than just her husband to help rear her young... This whole idea of 'it takes a village to raise a child' is exactly how we're supposed to live.
For millions of years, this world has been a great gift to nearly everything living on it, a planet whose atmosphere, temperature, air, water, seasons, and weather were precisely calibrated to allow us - the big us, including forests and oceans, species large and small - to flourish.
The existence of common features in different forms of life indicates some relationship between the different organisms, and according to the concept of evolution, these relations stem from the circumstance that the higher organisms, in the course of millions of years, have gradually evolved from simpler ones.
All of us are linear thinkers. We evolved in a world that was local and linear. You know, back 100,000, 200,000, millions of years ago, when we were evolving as a human species, nothing changed. You know, the life of your great-grandparents, you, your kids - it was the same. And so we are local and linear thinkers.
The earth's biosphere could be thought of as a sort of palace. The continents are rooms in the palace; islands are smaller rooms. Each room has its own decor and unique inhabitants; many of the rooms have been sealed off for millions of years. The doors in the palace have been flung open, and the walls are coming down.
The reason you see so many volcanoes on Venus is partly due to the fact that there's virtually no erosion there. So on Venus, you're seeing features, some of which are hundreds of millions of years old on the surface. On Earth, we do not see any surface features nearly that old - you only see much more recent features.
The belief that the animals exist because God created them - and that he created them so we can better meet our needs - is contrary to our scientific understanding of evolution and, of course, to the fossil record, which shows the existence of non-human primates and other animals millions of years before there were any human beings at all.
