It's not that living things die; it's that multicellular organisms die. But why? Every single-celled organism alive today has been in existence since life began over 3 billion years ago. This is because individual cells do not give birth, they divide. After cell division, the two cells that result are each as old as the single cell that preceded them.
Genitals are between the legs of every vertebrate. In those that don't have legs, it's between where the legs would be (the fins of fish) or where they were (the legs of reptiles that evolved into snakes, which still have them there). They got that way because they're an outgrowth of the excretory tract. In other vertebrates, the excretory and reproductive orifice is the same. It took the mammals to build it into a separate set of genitals.
When you think of yourself, you probably think of a single individual. In reality, you're a collection of human cells plus
In his response to comments by me, Jon Marks and Jennifer Raff, Wade does not take on any substantive aspect of the debate; rather, he misrepresents the science again and takes a shot at our credentials as scholars. Here is a very quick response to his comments, in hopes of correcting the record and getting this debate back to the science.
Wade's approach to race is particularly dangerous because his argument is that he is just a defender of scientific truth and that a cabal of left-leaning academics is obfuscating reality with oppressive, even fascistic, denials of the truth about race. Unfortunately, he is either ignorant of the actual data and diversity of research or he is willfully avoiding them.
