Six months ago, I got an email
0
12492
2181
00:14
from a man in Israel
1
14673
1407
00:16
who had read one of my books,
2
16080
1381
00:17
and the email said,
3
17461
1503
00:18
"You don't know me,
4
18964
2007
00:20
but I'm your 12th cousin."
5
20971
2472
00:23
And it said, "I have a family tree
6
23443
2377
00:25
with 80,000 people on it, including you,
7
25820
3904
00:29
Karl Marx,
8
29724
1154
00:30
and several European aristocrats."
9
30878
2600
00:33
Now I did not know what to make of this.
10
33478
2402
00:35
Part of me was like, okay,
11
35880
2351
00:38
when's he going to ask me to wire
12
38231
1960
00:40
10,000 dollars to his Nigerian bank, right?
13
40191
3697
00:43
I also thought, 80,000 relatives,
14
43888
3673
00:47
do I want that?
15
47576
1278
00:48
I have enough trouble with some of the ones
16
48854
1818
00:50
I have already.
17
50672
1437
00:52
And I won't name names, but you know who you are.
18
52109
3666
00:55
But another part of me said, this is remarkable.
19
55775
3249
00:59
Here I am alone in my office, but I'm not alone at all.
20
59024
2736
01:01
I'm connected to 80,000 people around the world,
21
61760
3560
01:05
and that's four Madison Square Gardens
22
65320
3377
01:08
full of cousins.
23
68697
1715
01:10
And some of them are going to be great,
24
70412
2937
01:13
and some of them are going to be irritating,
25
73349
2330
01:15
but they're all related to me.
26
75679
2816
01:18
So this email inspired me to dive into genealogy,
27
78495
3871
01:22
which I always thought was a very staid and proper field,
28
82366
3400
01:25
but it turns out it's going through a fascinating
29
85766
2925
01:28
revolution, and a controversial one.
30
88691
2493
01:31
Partly, this is because of DNA and genetic testing,
31
91184
3766
01:34
but partly, it's because of the Internet.
32
94950
3950
01:38
There are sites that now take
33
98900
1760
01:40
the Wikipedia approach to family trees,
34
100660
3167
01:43
collaboration and crowdsourcing,
35
103827
2353
01:46
and what you do is,
36
106180
1178
01:47
you load your family tree on,
37
107358
2882
01:50
and then these sites search
38
110240
1480
01:51
to see if the A.J. Jacobs in your tree
39
111720
2682
01:54
is the same as the A.J. Jacobs in another tree,
40
114402
2480
01:56
and if it is, then you can combine,
41
116882
3233
02:00
and then you combine and combine and combine
42
120115
1895
02:02
until you get these massive,
43
122010
1901
02:03
mega-family trees
44
123911
1850
02:05
with thousands of people on them,
45
125761
2501
02:08
or even millions.
46
128262
1415
02:09
I'm on something on Geni called
47
129677
2327
02:12
the world family tree,
48
132004
1926
02:13
which has no less than a jaw-dropping
49
133930
2557
02:16
75 million people.
50
136487
3530
02:20
So that's 75 million people connected by blood
51
140017
3840
02:23
or marriage, sometimes both.
52
143857
2480
02:26
(Laughter)
53
146337
2567
02:28
It's in all seven continents, including Antarctica.
54
148904
4185
02:33
I'm on it. Many of you are on it,
55
153089
2377
02:35
whether you know it or not,
56
155466
1704
02:37
and you can see the links.
57
157170
2464
02:39
Here's my cousin Gwyneth Paltrow.
58
159634
4592
02:44
She has no idea I exist,
59
164226
1883
02:46
but we are officially cousins.
60
166109
2691
02:48
We have just 17 links between us.
61
168800
4196
02:52
And there's my cousin Barack Obama.
62
172996
2693
02:55
(Laughter)
63
175689
1192
02:56
And he is my aunt's fifth great-aunt's husband's
64
176881
3625
03:00
father's wife's seventh great-nephew,
65
180506
3508
03:04
so practically my old brother.
66
184014
5065
03:09
And my cousin, of course,
67
189079
1523
03:10
the actor Kevin Bacon --
68
190602
1317
03:11
(Laughter) —
69
191919
1652
03:13
who is my first cousin's twice removed's
70
193571
2964
03:16
wife's niece's husband's first cousin once removed's
71
196535
2392
03:18
niece's husband.
72
198927
1210
03:20
So six degrees of Kevin Bacon,
73
200137
2135
03:22
plus or minus several degrees.
74
202272
4119
03:26
Now, I'm not boasting, because all of you
75
206391
2381
03:28
have famous people and historical figures
76
208772
2228
03:31
in your tree, because we are all connected,
77
211000
3667
03:34
and 75 million may seem like a lot,
78
214667
3163
03:37
but in a few years, it's quite likely
79
217830
2726
03:40
we will have a family tree
80
220556
1513
03:42
with all, almost all, seven billion people on Earth.
81
222069
4751
03:46
But does it really matter?
82
226820
1793
03:48
What's the importance?
83
228613
1342
03:49
And I do think it is important,
84
229955
1678
03:51
and I'll give you five reasons why, really quickly.
85
231633
2478
03:54
First, it's got scientific value.
86
234111
2820
03:56
This is an unprecedented history of the human race,
87
236931
3614
04:00
and it's giving us valuable data
88
240545
3431
04:03
about how diseases are inherited,
89
243976
2149
04:06
how people migrate,
90
246125
1868
04:07
and there's a team of scientists at MIT right now
91
247993
2920
04:10
studying the world family tree.
92
250913
2680
04:13
Number two, it brings history alive.
93
253593
2886
04:16
I found out I'm connected to Albert Einstein,
94
256479
3461
04:19
so I told my seven-year-old son that,
95
259940
2060
04:22
and he was totally engaged.
96
262000
2846
04:24
Now Albert Einstein is not some dead white guy
97
264846
3367
04:28
with weird hair.
98
268213
1210
04:29
He's Uncle Albert. (Laughter)
99
269423
4157
04:33
And my son wanted to know,
100
273580
1560
04:35
"What did he say? What is E = MC squared?"
101
275140
2157
04:37
Also, it's not all good news.
102
277297
2059
04:39
I found a link to Jeffrey Dahmer, the serial killer,
103
279356
3987
04:43
but I will say that's on my wife's side.
104
283343
2617
04:45
(Laughter) (Applause)
105
285960
2688
04:48
So I want to make that clear. Sorry, honey.
106
288648
2595
04:51
Number three, interconnectedness.
107
291243
2889
04:54
We all come from the same ancestor,
108
294132
3363
04:57
and you don't have to believe the literal Bible version,
109
297495
2568
05:00
but scientists talk about Y chromosomal Adam
110
300063
4088
05:04
and mitochondrial Eve,
111
304151
2853
05:07
and these were about 100,000 to 300,000 years ago.
112
307004
3316
05:10
We all have a bit of their DNA in us.
113
310320
3053
05:13
They are our great-great-great-great-great-great --
114
313373
2817
05:16
continue that for about 7,000 times --
115
316190
2740
05:18
grandparents,
116
318930
1815
05:20
and so that means we literally all are
117
320745
2646
05:23
biological cousins as well,
118
323391
2155
05:25
and estimates vary, but probably
119
325546
2556
05:28
the farthest cousin you have on Earth
120
328102
2702
05:30
is about a 50th cousin.
121
330804
2455
05:33
Now, it's not just ancestors we share, descendants.
122
333259
4181
05:37
If you have kids, and they have kids,
123
337440
2700
05:40
look how quickly the descendants accumulate.
124
340140
3465
05:43
So in 10, 12 generations,
125
343605
1693
05:45
you're going to have thousands of offspring,
126
345298
2131
05:47
and millions of offspring.
127
347429
1517
05:48
Number four, a kinder world.
128
348946
1989
05:50
Now, I know that there are family feuds.
129
350935
2489
05:53
I have three sons, so I see how they fight.
130
353424
2295
05:55
But I think that there's also a human bias
131
355719
2666
05:58
to treat your family a little better than strangers.
132
358385
2526
06:00
I think this tree is going to be bad news for bigots,
133
360911
3824
06:04
because they're going to have to realize
134
364735
3425
06:08
that they are cousins with thousands of people
135
368160
3610
06:11
in whatever ethnic group they happen
136
371770
1751
06:13
to have issues with,
137
373521
2262
06:15
and I think you look back at history,
138
375783
1885
06:17
and a lot of the terrible things we've done to each other
139
377668
3001
06:20
is because one group thinks another group is sub-human,
140
380669
2906
06:23
and you can't do that anymore.
141
383575
1465
06:25
We're not just part of the same species.
142
385040
1370
06:26
We're part of the same family.
143
386410
1767
06:28
We share 99.9 percent of our DNA.
144
388177
3636
06:31
Now the final one is number five,
145
391813
2301
06:34
a democratizing effect.
146
394114
1679
06:35
Some genealogy has an elitist strain,
147
395793
3457
06:39
like people say, "Oh, I'm descended
148
399250
1990
06:41
from Mary Queen of Scots
149
401240
1271
06:42
and you're not, so you cannot join my country club."
150
402511
3207
06:45
But that's really going to be hard to do now,
151
405718
2941
06:48
because everyone is related.
152
408659
1431
06:50
I'm descended from Mary Queen of Scots --
153
410090
2688
06:52
by marriage, but still.
154
412778
3353
06:56
So it's really a fascinating time
155
416131
3496
06:59
in the history of family,
156
419627
1556
07:01
because it's changing so fast.
157
421183
3507
07:04
There is gay marriage and sperm donors
158
424690
2575
07:07
and there's intermarriage on an unprecedented scale,
159
427265
4920
07:12
and this makes some of my more conservative cousins
160
432185
2226
07:14
a little nervous,
161
434411
1609
07:16
but I actually think it's a good thing.
162
436020
1804
07:17
I think the more inclusive the idea of family is,
163
437824
3829
07:21
the better,
164
441653
1027
07:22
because then you have more potential caretakers,
165
442680
2104
07:24
and as my aunt's eighth cousin twice removed
166
444784
4315
07:29
Hillary Clinton says --
167
449099
2127
07:31
(Laughter) —
168
451226
1744
07:32
it takes a village.
169
452970
1329
07:34
So I have all these hundreds and thousands,
170
454299
5263
07:39
millions of new cousins.
171
459562
1118
07:40
I thought, what can I do with this information?
172
460680
2741
07:43
And that's when I decided,
173
463421
1856
07:45
why not throw a party?
174
465277
2239
07:47
So that's what I'm doing.
175
467516
2236
07:49
And you're all invited.
176
469752
2560
07:52
Next year, next summer,
177
472312
1898
07:54
I will be hosting what I hope is
178
474210
1931
07:56
the biggest and best family reunion in history.
179
476141
4478
08:00
(Applause)
180
480619
1032
08:01
Thank you. I want you there.
181
481651
2402
08:04
I want you there.
182
484053
1112
08:05
It's going to be at the New York Hall of Science,
183
485165
2474
08:07
which is a great venue,
184
487639
2282
08:09
but it's also on the site of the former World's Fair,
185
489921
3780
08:13
which is, I think, very appropriate,
186
493701
3645
08:17
because I see this as a family reunion
187
497346
2230
08:19
meets a world's fair.
188
499576
1418
08:20
There's going to be exhibits and food, music.
189
500994
2941
08:23
Paul McCartney is 11 steps away,
190
503935
2309
08:26
so I'm hoping he brings his guitar.
191
506244
3600
08:29
He hasn't RSVP'd yet, but fingers crossed.
192
509844
2735
08:32
And there is going to be a day of speakers,
193
512579
2391
08:34
of fascinating cousins.
194
514970
2001
08:36
It's early, but I've already,
195
516971
1182
08:38
I've got some lined up.
196
518153
1872
08:40
Cass Sunstein, my cousin who is perhaps
197
520025
2724
08:42
the most brilliant legal scholar, will be talking.
198
522749
2388
08:45
He was a former member of the Obama administration.
199
525137
3239
08:48
And on the other side of the political spectrum,
200
528376
2824
08:51
George H.W. Bush, number 41, the father,
201
531200
3132
08:54
