Examples of Natural Selection
Darwin's Finches are an example of natural selection in action. They are an excellent example of the way species' gene pools have adapted in order for long term survival via their offspring. See this tutorial for more elaborate info on natural selection as exemplified by Darwin's finches...
Darwin and Natural Selection
This tutorial investigates the genetic diversity in more detail. It also delineates how certain alleles are favored over other alleles in natural selection. ..
Adaptive Radiation
The diversification of several new species from a recent ancestral source, each adapted to utilize or occupy a vacant adaptive zone is referred to as adaptive radiation. 'Darwin's Finches' exemplified adaptive radiation. For more elaborate info on adaptive radiation, read this tutorial...
Sensory Systems
A sensory system is a part of the nervous system consisting of sensory receptors that receive stimuli from the internal and external environment, neural pathways that conduct this information to the brain and parts of the brain that processes this information. Know the different sensory systems of the human body as elaborated by this tutorial...
Consciousness and Behavior
Human consciousness and behavior are an interesting topic since they are determined and controlled by the brain. Consciousness can be defined by behavior or by electrical pattern of brain activity. Read this tutorial to learn about brain activities, such as sleep, attention, emotion, motivation, consciousness disorders, learning, and memory...
The Evolutionary Development of Multicellular Organisms
Multicellular organisms evolved. The first ones were likely in the form of sponges. Multicellularity led to the evolution of cell specializations that form tissues. Another major event was the evolution of sexual reproduction. The emergence of sex cells in the timeline provided a means for organisms to further diversify. Know more about these crucial events in geologic time in this tutorial...
