公司请第三方律师公司办得eb2，现在file 140，请问要不要把老婆的信息也填上去？
老婆现在opt，正准备延期。填上去会不会有影响？
如果不填的话，到485再填的会不会引起怀疑什么的？
律师发的问卷有一个问题是：
8) Are all family members applying for Adjustment of Status with you? Yes
or No
该填yes，还是no呢？
多谢了

Melissa Wilson Sayres, an assistant professor with ASU's School of Life
Sciences, said, “Instead of ‘survival of the fittest’ in biological sense
, the accumulation of wealth and power may have increased the reproductive
success of a limited number of ‘socially fit’ males and their sons.”
“We … detect a cluster of major non-African founder haplogroups in a
narrow time interval at 47–52 kya, consistent with a rapid initial
colonization model of Eurasia and Oceania after the out-of-Africa bottleneck
,” wrote the authors. “In contrast to demographic reconstructions based on
mtDNA, we infer a second strong bottleneck in Y-chromosome lineages dating
to the last 10 ky.”
After applying DNA calibration and Y-chromosome dating techniques, the
researchers arrived at their “bottleneck” findings. The male-specific
bottleneck, the researchers suggested, was caused by “culture changes
affecting variance of reproduction success among males.”
