Your Answer: Explanation The brain of anthropoids is larger, relative to body weight, than that of prosimians and is characterized by a complicated pattern of folds and fissures on the surface. Question 42 of 55 Another evolutionary trend in primates involves the development of offspring both before and after birth. Your Answer: Explanation Gestation periods (The period of development in the uterus from conception until birth) are relatively long, allowing for the development of the more complex brain. Question 43 of 55 Ever since recorded history began, and probably before, people have found pieces of rock and other hard material with indentations from the remains of dead organisms. These are called fossils, and the totality of these artifacts and their placement in rock striations is referred to as the fossil record. Your Answer: Explanation

The fossil record is one of the primary sources of data relevant to the study of evolution. Scientists examine fossils in order to understand the process of evolution and the way specific species have evolved. Question 44 of 55 Dating methods, such as radiometric (but not carbon-14 , which works only for 0-50,000 years before present), show that some of these fossils are tens of millions of years old. Your Answer: Explanation Various dating methods have been used and are used today, and while there is some variance in the results from these methods, nearly all of them provide evidence for a very old Earth and for evolution. Question 45 of 55 The geologist sees Relative Time where two or more events are compared without any numerical reference. Your Answer: Explanation Relative time is where an event is compared in time relative to another event, as opposed to absolute time, where a specific date and time is specified. For example--the Beatles first performed in the United States during the presidency of Lyndon B. Johnson; or January precedes February. Question 46 of 55 Absolute time is measured in some unit (seconds, minutes, hours or years) from some starting point going either forward or backwards. Your Answer: Explanation Examples: this is 2003 A.D.; Herodotus studied deltas in Egypt about 420 B.C.; this lecture started l5 minutes ago. Question 47 of 55 The difference between geologic time and the examples given from every day life is the length of time involved. Your Answer: Explanation Geologic time is vast, with immense and variable blocks in each relative unit, and very large numbers of years in absolute measurements.
