Subject: Error in method call - need help to understand

I was trying to call a method as below:

$array = []
array_1 = %w(tuna salmon herring)
array_2 = %w(crow owl eagle dove)

def parser (*argument)
  argument.each do |item|
    $array << item
  end
end

parser (array_1,array_2)
$array.flatten!
puts $array

Error:
=====
D:/Rubyscript/My ruby learning days/Scripts/test.rb:13: syntax error, u
nexpected ',', expecting ')'
parser (array_1,array_2) # taking multiple arguments generates error
                ^

No I fixed the code by removing the space in the method call of parser
as below:

$array = []
array_1 = %w(tuna salmon herring)
array_2 = %w(crow owl eagle dove)

def parser (*argument)
  argument.each do |item|
    $array << item
  end
end

parser(array_1,array_2) # taking multiple arguments generates error
$array.flatten!
puts $array

Output:
=======
tuna
salmon
herring
crow
owl
eagle
dove

But in the first method why such `space` causes the errors to be thrown
up?
