Research in the genetics of behavioral traits, undertaken by family studies, twin studies, and adoption studies, has revealed information on normal variation in cognitive abilities as well as specific learning disabilities (primarily dyslexia). Genetic evaluation of learning disabled students have implications for counseling and recurrence risk…

Reviews recent books on science for readers from age nine through young adult grouped according to the following categories: astronomy, computers, electronic musical instruments, and genetics. (RBW)

Studies by the late English psychologist Cyril Burt of IQ scores of separated twins strongly suggested that intelligence was inherited. A summary of recent research costs doubt upon the validity of Burt's work. (SL)

Modern technology in life and health sciences brings a new understanding to the study of cells and as a result, the National Science Education Standards emphasize understanding of science and technology. This ERIC Digest describes the central role of cell biology (cytology) in understanding these areas and explains conceptual difficulties and…

Some concepts in genetics are difficult for many students to understand. This document provides hands-on, cost efficient, fun activities for students to help them better understand abstract concepts in genetics. Each activity includes: purpose, introduction, materials, procedures, results and conclusion. Some of the topics explored are: (1)…

This guide presents a module for college students on ribonucleic acid (RNA) and its role in biology. The module aims to integrate the latest research and its findings into college-level biology and provide an opportunity for students to understand biological processes. Four activities are presented: (1) "RNA Structure: Tapes to Shapes";…

This digest explains how to inform high school students and their parents about the human genome project (HGP) and how the information from this milestone finding will affect future biological and medical research and challenge science educators. The sections include: (1) "The Emerging Legacy of the HGP"; (2) "Transforming How…

Many teachers avoid controversial topics because they do not want to upset students or parents, do not know appropriate instructional strategies, and fail to recognize the importance of motivating students through placing science in its relevant context. An example is provided for use in a methods course for helping future high school teachers to…

Presents opposing philosophies relating to the nature of aggression in man. One position advocates that human aggression is the product of evolution and is inherited, while the other proposes a cultural pattern model of aggression and uses two empirical tests in an attempt to disprove the genetic model.

Minutiae, ends and junctions of finger tip or palm lines, were analyzed in a sample of 115 normal adult individuals, 40 cases of Down's syndrome, and 130 normal children (aged 6 to 14 years). (DB)

Discusses interdemic (interpopulation) selection, the Levins and Boorman-Levitt models, and the significance of group selection for ecology. (JR)

Reviewed were clinical and genetic features of 27 cases of the Noonan Syndrome, a condition with characteristics such as webbing of the neck, short stature, frequent congential heart lesions, and chromosomal irregularities. (DB)

Describes the basic logic behind the modern view of evolution theory. Despite gaps in fossil records, evidence is indicative of the origin of life from nonliving molecules and evolution of higher forms of life from simpler forms. (PS)
