D.3.4 Describe the major anatomical features that deﬁne humans as primates.Vision: binocular, stereoscopic vision provides over-lapping fields of vision and good depth perception. Face shape and snout: snout is shorter, so sense of smell is less good.These learned behaviors (as opposed to innate behaviors which are the result of genetic evolution) are the culture.New methods, inventions, or customs can be passed on (cultural evolution).In K-40 dating the proportions of K-40 atoms to Ar-40 atoms is measured.The half-life of K-40 is 1.26 billion years so it is useful for dating samples over 100,000- 1 million years old. The time it takes for the radioactivity to fall to half of its original level D.3.3 Deduce the approximate age of materials based on a simple decay curve for a radioisotope.In radiocarbon dating the percentage of surviving C-14 atoms is measured.
Deduce the approximate age of materials based on a simple decay curve for a radioisotope. Describe the major anatomical features that define humans as primates.
Teeth shape/Dental arrangement: generalized dental plan so primates can have an omnivorous diet.
Brain size and specialization: brain is large and complex than other mammals. Knowledge of approximate dates and distribution of the named species is expected.
Outline the method for the dating of rocks and fossils using radioisotopes, with reference to 14C and 40K.
Paleoanthropology is an example of the diverse aspects of science, in that it is a data-poor science with largely uncontrollable subject matter.
