He believed that their immense antlers did not only evolve for combat, but that they were also visual representations. Gould and many modern-day scientists have concluded that the antlers served as megaloceros giganteus, in which the male elk with large antlers were more suited to megaloceros giganteus females.

Knight Frequent debates occur as to whether or not sexual selection led to the Irish elk's extinction. Sexual selection can increase or decrease a population's chance of extinction, due to behaviors such as male-male competition and female choice. Also, sexual harassment by males can result in lower female fecundity or even death.

Selection must, therefore, favor megaloceros giganteus less extreme male genotypes, and generating a scenario seems impossible where males with larger antlers are still selected for when the lifetime reproductive success of males with megaloceros giganteus antlers approaches zero as required for deterministic extinction to occur.

This can pose significant threats to population survival. Females may adaptively avoid the accumulation of inbreeding, so that female choice might increase effective population size. This also supports the belief that the large antler size was used for social display. The antlers were more compact, and the tines near the base large and palmate.

Lived in Mid-Pleistocene Germany. The large antlers of the moose, although small relative to the giant deer, led to Megaloceros giganteus being known as an elk. And the fact that the earliest fossil findings and even today the best remains come from Ireland lead to the species being dubbed the "Irish elk.

However, Megaloceros giganteus was a relatively recent arrival megaloceros giganteus Ireland, first appearing somewhat about 37, years ago and lasting megaloceros giganteus about 32, years ago IPCC and then again inhabiting Ireland during the Allerod interstadial phase at the end of the last glaciation, from about 12, to 11, years ago IPCC ; Gould A significant collection of M.

The earlier taxon —sometimes considered a paleosubspecies M. Fossils and historical importance The earliest known drawing of antlers of giant deer date to Gould Thomas Megaloceros giganteus provided the first published description. Inthe first discovery in continental Europe of fossils of this giant deer were made in Germany Gould The giant deer and its massive antlers has been important in debates on evolutionary theory.

Gould notes that "every great evolutionist has used the giant deer megaloceros giganteus defend his favored views. If God is perfect, and He made a perfect creation, why would He allow any of his created organisms to become extinct?
