The concept of a sensitive period‚ that is a phase during development when learning a particular skill can occur more effectively than later on in life‚ is well known in nature. A few examples are imprinting in ducks and song learning for songbirds (Clark 2009). The sensitive period is sometimes regarded as critical‚ implying that‚ once it is past‚ that specific skill can no longer be learnt. The idea that human language is normally acquired during a critical period was proposed by Lenneberg with

The fossil records beautifully preserved in the shale rock‚ tell the story of the Cambrian Explosion‚ a period where organisms evolved at an explosive rate into many diverse creatures that are the ancestors to many of the organisms today‚ including humans. Over the past century‚ the Burgess Shale has unearthed new books to earth’s history and still

Walcott in 1907‚ the main shale site known and studied today was deposited at the base of a 160m cliff wasn’t officially discovered until 1909. Fossils found within are estimated to about 505 million years old‚ dating to the mid to late Cambrian period. During this period‚ the site rested on the west coast of North America very near the equatorial position as a coastal shallow reef; as graphically depicted in the following model.

child’s sensitive period for order. I will explain how it is catered for in the classroom‚ referring to materials and activities.

Up until 1947‚ it was believed that the Cambrian Explosion marked the first true abundance of multicellular life. However‚ this was discovered to be untrue after Sir Douglas Mawson and R.C. Sprigg mistakenly came across numerous "fossil jellyfish" in the Ediacara Hills while observing what was originally believed to be sandstones belonging to the lowest strata of the Cambrian. At first‚ these finding were dismissed as "fortuitous inorganic markings."(AAS Biographical Memoirs.) Several years later

Quaternary Period 2 to 0 Million Years Ago Summary The Quaternary Period began about 1.8 million years ago and consists of two epochs: The Pleistocene Epoch‚ which is 1.8 million to 11‚000 years ago‚ and The Holocene Epoch‚ which is 11‚000 years ago to present. During this time there was very little movement of the continents themselves (Figure 1.3). During this period there were repetitive cycles of cold and warm climate that created the advancing and retreating of ice sheets. The moving of

question “are there critical periods for the development of social competency?” one must first clearly define the key elements of the question. A critical period is defined as a time when a certain development must happen if it is to ever happen (Strassen Berger‚ 2006).
