The influence of fatherhood on the science of Charles Darwin

There are drawings in Charles Darwin’s papers that defy explanation — until we remember that Darwin and his wife Emma had a huge family of ten (rambunctious) children. Scholars believe that a young Francis Darwin —the naturalist’s son— drew this on the back of Darwin’s manuscript for On the Origin of Species.

UC Berkeley psychologist Dacher Keltner has noted that Darwin’s family life may have inspired some of his scientific writing. When his daughter Annie died at age 10, Darwin started to have deep insights about the place of suffering and compassion in human experience.

That led him to argue, in The Descent of Man, that sympathy is our strongest instinct, sometimes stronger than self-interest, and he argued that it would spread through natural selection, for “the most sympathetic members, would flourish best, and rear the greatest number of offspring.” 

This point was totally forgotten by evolutionary science for quite some time. Well, given all the awful things humans do to each other, how could you make the case that sympathy is our strongest instinct?

The answer lies in the dependence and vulnerability of our children. Little baby chimpanzees eat by themselves; human babies can’t. Baby chimpanzees sit up on their own; you sit up a human baby, and they go, “Watch out, man, my head’s really big!” Boom!

Their heads are so big because their brains are so big. To fit their big heads through the human birth canal—which narrowed as we started to walk upright on the African savanna—our babies were born profoundly premature and dependent upon people to take care of them.

In fact, our babies are the most vulnerable offspring on the face of the Earth. And that simple fact changed everything. It rearranged our social structures, building cooperative networks of caretaking, and it rearranged our nervous systems. We became the super caregiving species, to the point where acts of care improve our physical health and lengthen our lives. We are born to be good to each other.

The vulnerability of our children transformed human relationships and made compassion essential to our survival →

Walt Whitman "I sing the body electric"

I have perceiv’d that to be with those I like is enough, To stop in company with the rest at evening is enough, To be surrounded by beautiful, curious, breathing, laughing flesh is enough, To pass among them or touch any one, or rest my arm ever so lightly round his or her neck for a moment, what is this then? I do not ask any more delight, I swim in it as in a sea.

It’s the Great Pumpkin, Charlie Brown (1966)

The Moon in Motion

Happy New Year! And happy supermoon! Tonight, the Moon will appear extra big and bright to welcome us into 2018 – about 6% bigger and 14% brighter than the average full Moon. And how do we know that? Well, each fall, our science visualizer Ernie Wright uses data from the Lunar Reconnaissance Orbiter (LRO) to render over a quarter of a million images of the Moon. He combines these images into an interactive visualization, Moon Phase and Libration, which depicts the Moon at every day and hour for the coming year. 

Want to see what the Moon will look like on your birthday this year? Just put in the date, and even the hour (in Universal Time) you were born to see your birthday Moon.

Our Moon is quite dynamic. In addition to Moon phases, our Moon appears to get bigger and smaller throughout the year, and it wobbles! Or at least it looks that way to us on Earth. This wobbling is called libration, from the Latin for ‘balance scale’ (libra). Wright relies on LRO maps of the Moon and NASA orbit calculations to create the most accurate depiction of the 6 ways our Moon moves from our perspective.

1. Phases

The Moon phases we see on Earth are caused by the changing positions of the Earth and Moon relative to the Sun. The Sun always illuminates half of the Moon, but we see changing shapes as the Moon revolves around the Earth. Wright uses a software library called SPICE to calculate the position and orientation of the Moon and Earth at every moment of the year. With his visualization, you can input any day and time of the year and see what the Moon will look like!

2. Shape of the Moon

Check out that crater detail! The Moon is not a smooth sphere. It’s covered in mountains and valleys and thanks to LRO, we know the shape of the Moon better than any other celestial body in the universe. To get the most accurate depiction possible of where the sunlight falls on the lunar surface throughout the month, Wright uses the same graphics software used by Hollywood design studios, including Pixar, and a method called ‘raytracing’ to calculate the intricate patterns of light and shadow on the Moon’s surface, and he checks the accuracy of his renders against photographs of the Moon he takes through his own telescope.

3. Apparent Size 

The Moon Phase and Libration visualization shows you the apparent size of the Moon. The Moon’s orbit is elliptical, instead of circular - so sometimes it is closer to the Earth and sometimes it is farther. You’ve probably heard the term “supermoon.” This describes a full Moon at or near perigee (the point when the Moon is closest to the Earth in its orbit). A supermoon can appear up to 14% bigger and brighter than a full Moon at apogee (the point when the Moon is farthest from the Earth in its orbit). 

Our supermoon tonight is a full Moon very close to perigee, and will appear to be about 14% bigger than the July 27 full Moon, the smallest full Moon of 2018, occurring at apogee. Input those dates into the Moon Phase and Libration visualization to see this difference in apparent size!

4. East-West Libration

Over a month, the Moon appears to nod, twist, and roll. The east-west motion, called ‘libration in longitude’, is another effect of the Moon’s elliptical orbital path. As the Moon travels around the Earth, it goes faster or slower, depending on how close it is to the Earth. When the Moon gets close to the Earth, it speeds up thanks to an additional pull from Earth’s gravity. Then it slows down, when it’s farther from the Earth. While this speed in orbital motion changes, the rotational speed of the Moon stays constant. 

This means that when the Moon moves faster around the Earth, the Moon itself doesn’t rotate quite enough to keep the same exact side facing us and we get to see a little more of the eastern side of the Moon. When the Moon moves more slowly around the Earth, its rotation gets a little ahead, and we see a bit more of its western side.

5. North-South Libration

The Moon also appears to nod, as if it were saying “yes,” a motion called ‘libration in latitude’. This is caused by the 5 degree tilt of the Moon’s orbit around the Earth. Sometimes the Moon is above the Earth’s northern hemisphere and sometimes it’s below the Earth’s southern hemisphere, and this lets us occasionally see slightly more of the northern or southern hemispheres of the Moon! 

6. Axis Angle

Finally, the Moon appears to tilt back and forth like a metronome. The tilt of the Moon’s orbit contributes to this, but it’s mostly because of the 23.5 degree tilt of our own observing platform, the Earth. Imagine standing sideways on a ramp. Look left, and the ramp slopes up. Look right and the ramp slopes down. 

Now look in front of you. The horizon will look higher on the right, lower on the left (try this by tilting your head left). But if you turn around, the horizon appears to tilt the opposite way (tilt your head to the right). The tilted platform of the Earth works the same way as we watch the Moon. Every two weeks we have to look in the opposite direction to see the Moon, and the ground beneath our feet is then tilted the opposite way as well.

So put this all together, and you get this:

Beautiful isn’t it? See if you can notice these phenomena when you observe the Moon. And keep coming back all year to check on the Moon’s changing appearance and help plan your observing sessions.
