Biological anthropologists have discovered a previously unknown fossil species. The species lived about 4.4 million years ago in

Africa. The dating of this fossil species places it closer in time to the last common ancestor of humans and chimpanzees than most other known fossil species. This newly discovered species has an interesting mix of traits. For example, it has adaptations for climbing in trees as well as for walking on two legs on the ground. It does not directly resemble any of the living ape species, which suggests that the living ape species (including humans) have each become adapted for their own environmental contexts over time. What is the primary subfield of biological anthropology addressed in this research? Group of answer choices primatology human biology forensic anthropology paleoanthropology

Answer:

The correct response is paleoanthropology.

Explanation:

Paleoanthropology is the branch of anthropology that examines the origins of early humans and theorizes about their evolutionary development.  Dating of fossils requires technical knowledge related more to the physical sciences through understandings of geologic strata, radioactive-decay rates, and other chemical and genetic tests.  Physical anthropologists study past populations of fossil hominins and nonhuman primates in order to try to piece together the evolutionary history of our closely related species.

Explanation:

A human has two sexual characteristics primary and secondary.

The primary characteristics are sex chromosomes, gonads, level of sex hormones, anatomy of internal genitalia and anatomy of external genitalia. They are present at birth.

The secondary sex characteristics are breasts, menstrual cycle and accumulation of fat in certain parts of the body which gives rise to the hourglass body form for women.

Pubic hair grows in both sexes.

Describe several heuristics that you might use or that you have used when deciding whether you should (a) study especially hard
Norma-Jean [14]

The answer to this question is explained below.

Explanation:

There are two parts in this question. One is the possible heuristics when deciding whether you should study hard for the test, and secondly when ask someone for a date, or accept a date.

Studying hard for the test:

In deciding whether study hard for the test, you should consider the following heuristics:

  • Think of your previous experience about studying and see if it worked for you.
  • If it worked for you, go for it.
  • If it did not work for you, try a better solution this time.

Asking someone for date(or vice versa):

In deciding whether to go on a date with someone, the following heuristics should be kept in mind:

  • Think that what you know about the person you are asked or being asked about the date
  • Know what your own limits are
  • Make sure you know the person well before asking for a date.
