Sometimes the head and heart lines merge into one strong line that cuts right across the hand, forming a simian line. This line can appear on one or both hands. The simian line is often heavy and chainlike. In many cases, there are semi-simian formations where there are vestigial pieces of head and heart lines left on the hand.
The word "simian:' meaning "monkeylike." is used because early palmists thought that monkeys had this formation on their hands. I have visited zoos and studied the hands of many apes and monkeys, even going as far as taking hand prints from a baby Barbary ape when I was in Gibraltar. I discovered that the lines on any monkey or ape hand are the same as human ones and that these creatures
do not have a "simian" line formation. The skin ridge pat-terns are quite different from those of humans though.
The semi-simian line
People with simian lines find it difficult to lead a normal, balanced life. They focus entirely on either their work or their relationship, or on something else in a one-sided manner. They hold on to resentments and then explode in a tantrum or floods of tears. These people can be very obstinate.
Semi-simian lines are also uncommon. They mean much the same as a simian line, but the person is likely to develop a more balanced attitude with time and experience.
