Yes, the name of the science that studies how "blobs" of cells become differentiated into first tissues then organs then organ systems is called "embryology", and the specific topic you want to read about is called "morphogenesis"--see this link:moe darklight said:Hi, (I think I started a thread similar to this earlier) I was wondering if anyone knows of any good websites or books or DVD's that focus on the evolution of organs and organ systems. That is, the point at which a group of cells stopped being a "blob" and started differentiating into organs with separate functions (I'm sure this has a name, but I don't know what it is so I don't know what to look for lol).
The theory of evolution states that organisms change over time through the process of natural selection, where advantageous traits are more likely to be passed on to future generations. This also applies to organs, as they can evolve to better suit an organism's environment and needs.
Scientists study the evolution of organs through comparative anatomy, looking at the similarities and differences in the structure and function of organs across different species. They also use genetics and molecular biology to analyze the genetic basis of organ development and evolution.
Yes, organs can evolve to become obsolete if they are no longer needed for survival. This is known as vestigiality, where an organ or structure that was once useful becomes reduced or non-functional over time.
Yes, there are many examples of organs that have evolved significantly. One well-known example is the evolution of the human brain, which has increased in size and complexity over millions of years. Another example is the evolution of the vertebrate eye, which has improved in its ability to detect light and form images.
The environment plays a significant role in the evolution of organs. The selective pressures of the environment can drive changes in organ structure and function, as organisms with advantageous traits are more likely to survive and reproduce. Additionally, changes in the environment can also lead to the evolution of new organs to better adapt to new conditions.
