Until recently, genetics has dismissed the idea attributed to naturalist Jean-Baptiste Lamarck in the early 1800s that acquired traits were passed from one generation to the next. It was thought that the health and fitness of parents was of no consequence to succeeding generations. Data now suggest this is not entirely the case.
I’ve written in the past about DNA, genes and how DNA operates like a big computer network. In this article I wanted to tell how that network functions. That is, what mechanisms control the expression of genes
Anthropology has two branches, one dealing with the cultural aspects of humanity and the other with the physical. I’ve been fascinated with both since my early adolescence.
On a number of occasions I’ve explained how scientific data is collected, analyzed, interpreted and presented. I’ve told how scientists must reveal their methods so others can try reproducing their results. I’ve stated that results are always tentative until new discoveries confirm or contradict them.
Whales and dolphins are among the most fascinating animals on the planet. That they descended from four-legged land animals makes their story compelling.
Though scientific discoveries in the past 50 or 60 years have been phenomenal, the preceding century changed the way we view the universe and our place in it like no other time in history.
More and more planets are being discovered orbiting around stars far from Earth. When we think about the possibility of their supporting life there is one requirement we seldom consider. Those planets will probably need to have a magnetosphere somewhat like that of the Earth’s.
There is a great deal of misunderstanding of the basic tenets of the Theory of Evolution. The main source of confusion stems from those who deliberately twist the principles to advance their own agenda.
My father was intrigued by the mathematics he knew, but never understood what “higher” math was good for. Calculus was a mystery to him and he couldn’t conceive of more abstract mathematics.
I have written previously about the use of models and algorithms to study various scientific phenomena. I had my first experience with these methods in my first job for which my education was important.
