Fossils document the order of appearance of groups and they tell us about some of the amazing plants and animals that died out long ago.
Fossils can also show us how major crises, such as mass extinctions, happened, and how life recovered after them.
Near-whiteout conditions gave way to soap-flake flurries as we ambled up the long driveway to the massive brick and wood home.
One of the more magical moments happened as evening approached.
The weekend was filled with long walks, multi-branching conversations with people stepping in and out of the discussion as they had something to add or take in, a constant array of food and drink on the massive kitchen island, games, a terrible jigsaw puzzle, hot tub shenanigans, and lots and lots of hugs and words of love and appreciation. Was I a dedicated entrepreneur, or an opportunistic hedonist? And the more the pendulum swung, the less I was able to contain the disparate aspects of my life, embracing the highest highs and desperately sucked into the lowest lows. But it’s also better (for me) than the alternative so many people in my generation live — structured, balanced, even-keeled lives of quiet contentment punctuated by the occasional big night out or trip-of-a-lifetime. I love when they come out and let loose with my band of carousers, and I love putting my feet up at their homes and watching football together.
swung wide between soused off-duty nights and attentive parenting weekends, knocking relationships sideways, swinging back through the middle ground for a short time, before drifting wildly in another direction. I know all too well the consequences of my own lifestyle — the burnt mornings; the solitary slog up my stairs to a forlorn bedroom; the days of stress and minor terror when a client goes sideways and I’m watching our revenue shift in the wrong direction; my mom asking me if I’m happy; my daughter asking if I’m lonely.
So there we were, in a multi-bedroom, four story mountain house in Vail, drinking cocktails, cooking together, laughing, and celebrating.
Since then, geologists have made many tens of thousands of radiometric age determinations, and they have refined the earlier estimates.Current understanding of the history of life is probably close to the truth because it is based on repeated and careful testing and consideration of data.
