The Bronfenbrenner ecological model examines human development by studying how human beings create the specific environments in which they live. In other words, human beings develop according to their environment; this can include society as a whole and the period in which they live, which will impact behavior and development.
Whereas earlier statements of ecological systems theory focused on characteristics of the environment, the goal of the bioecological model was to explicate how characteristics of the developing person influenced the environments to which the person was exposed and how they were affected by the environment. [3] The bioecological model is ...
The tree of life or universal tree of life is a metaphor, conceptual model, and research tool used to explore the evolution of life and describe the relationships between organisms, both living and extinct, as described in a famous passage in Charles Darwin's On the Origin of Species (1859). [1]
A consumer in a food chain is a living creature that eats organisms from a different population. A consumer is a heterotroph and a producer is an autotroph.Like sea angels, they take in organic moles by consuming other organisms, so they are commonly called consumers.
Early humans were social and initially scavenged, before becoming active hunters. The need to communicate and hunt prey efficiently in a new, fluctuating environment (where the locations of resources need to be memorized and told) may have driven the expansion of the brain from 2 to 0.8 Ma. Evolution of dark skin at about 1.2 Ma. [39]
