List of Unsolved Biological Problems

For Young Scientists,

       Here are the problems that have been left unsolved in Biology history. Found on Wikipedia, not the best source, but still biological problems waiting to be solved.

• Arthropod head problem, a long-standing zoological dispute concerning the segmental composition of the heads of the various arthropod groups, and how they are evolutionarily related to each other.
• Biological aging: there are a number of hypotheses why senescence occurs including those that it is programmed by gene expression changes and that it is the accumulative damage of biological processes.
• Extraterrestrial life: might life which does not originate from planet Earth also have developed on other planets?
• Paradox of the plankton: the high diversity of phytoplankton seems to violate the competitive exclusion principle.
• Cambrian explosion: what is the cause of the apparent rapid diversification of multicellular animal life around the beginning of the Cambrian, resulting in the emergence of almost all modern animal phyla?
• In cell theory, what is the exact transport mechanism by which proteins travel through the Golgi apparatus?
• Evolution of sex: what selective advantages drove the development of sexual reproduction, and how did it develop?^[1]
• Butterfly migration: How do the descendants of Monarch butterfly all over Canada and the US eventually, after migrating for several generations, manage to return to a few relatively small overwintering spots?

How to get Educated Online For Free

Have you ever wondered if you could just take a class to learn but not for a degree? Is the cost stopping you? Learning can be an expensive hobby, but not when you find the right online resources. You want lectures from Stanford professors? Whole classes of lectures? A variety of subjects? You can find all this and more online.
Most people I know use YouTube to search for music videos, or to look at the latest new viral video. Did you know you can also use YouTube as a learning resource? Check out this video series I found on Human Behavioral Biology. The whole Stanford course! You do not even need a textbook, I’ve just been watching in sections each day and taking notes, exercising the mind.
This is not the only video series of a class online. Check out this website comprehensive list of free lectures online. Also as I come across more sites I will list them on the Education page, the tab next to Home above this article.
