Life, as we know it today, is presumed to have started in the sea and many of them were likely eukaryotic animal-like organisms. Because of the expanding diversity of animal life forms, taxonomists eventually came up with a classification scheme to group them into various phyla. Know more about the early animals that were likely the first ones to roam the ancient seas through this tutorial...
This lesson looks at population attributes, regulation, and growth. It also covers population genetics, particularly genetic variations, natural selection, genetic drift, genetic migration, and speciation...
Gregor Mendel's studies into Monohybrid and Dihybrid crossing and Charles Darwin's study of evolution and natural selection have led to studies that actively manipulate the phenotype of offspring by selective breeding in animals and plants. ..
The evolution of the species of the genus "Homo" led to the emergence of modern humans. Find out more about human evolution in this tutorial that elaborates on the different Homo species in the early geologic time.

This tutorial looks at sex determination via the sex chromosomes, X and Y. Read it to get more info on X and Y chromosomes and the genetic traits inherited via these two...
This tutorial investigates the genetic diversity in more detail. It also delineates how certain alleles are favored over other alleles in natural selection.
