devastated the marine biota. Tabulate and rugose corals‚ blastoid echinoderms‚ graptolites‚ and most crinoids died out‚ as did the last of the trilobites. Articulate brachiopods and one lineage of crinoids survived‚ but never again dominated the marine environment. All modern crinoids have evolved from this lineage. Crinoid bodies consist of three main parts: A calyx or aboral cup‚ the arms and

The societies of Europe‚ North America‚ and Africa were very diverse in 1492. Religion was also a key factor in the societies. The social classes showed each continent how to live their live therefore it is a good factor. The family structure in each society played a very important role in the in 1492.

The Essence of Being Women and Native. When human beings are uprooted from their ancestral lineage‚ their work‚ social relationships‚ marriage‚ parenting‚ and religion change.

theories have been in place‚ the heated debate regarding the origin of birds and their relationship to dinosaurs has raged on. After the 1860s birds have been hypothesized as being closely related to an ample assortment of extant and extinct reptile lineages. These include a diversity of basal archosaurs and archosauromorphs‚ pterosaurs‚ crocodylomorphs (including modern crocodylians and their Mesozoic relatives)‚ and various theropod ornithischian dinosaurs. Phylogenetic systematics is the field in

we learn that in the 7th century CE‚ the nomadic Bedouin people inhabited the arid steppes of Arabia. The Bedouin people of this time politically subscribed to tribal affiliations; the heads of these ancient tribal organizations were based on family lineage. The Bedouin secured income through caravan trade‚ which dominated the region as far as their economies went. The two most powerful trade centers along the Red Sea were Mecca and the city of Medina.(Suarez‚ 1‚2) Religious beliefs at this time in ancient Arabia before

species have provided valuable insights into angiosperm (flowering plant) genome structure‚ function and evolution. For example‚ A. thaliana has experienced two genome duplications since its divergence from Carica‚ with rapid DNA sequence divergence‚ extensive gene loss and fractionation of ancestral gene order eroding the resemblance of A. thaliana to ancestral Brassicales1. Compared with an ancestor at just a few million years ago‚ A. thaliana has undergone a ~30% reduction in genome size2 and

Savannahs will sometimes let out a snake hiss. Which comes from their Serval lineage‚ this noise is made to imitates a snake in times of danger. These breeds are both super healthy.

Extinction Extinction is the termination of evolutionary lineage. The most common extinction event is the loss of a species. There are many reasons why a species might die out. Human intervention (either directly or indirectly) has become the leading cause of species extinction (possibly for the last fifteen thousand years). Species and Populations An important distinction must be made between true extinction and extirpation. Extirpation is the loss of a population‚ or loss of a species
