Dominant organisms in tertiary time period?
During the Tertiary period, dominant organisms included early mammals, large birds, marine mammals like whales and dolphins, and diverse plant species. This period saw the rise of modern mammals, along with the evolution of grasslands, forests, and flowering plants. The Tertiary period also saw the decline of dinosaurs and the rise of more familiar animal groups.
Can recessive genes become dominant?
Recessive genes do not become dominant. Dominant genes mask the expression of recessive genes in the presence of both alleles. However, if a recessive gene is selected for over time through breeding, it can become more prevalent in a population.
What are the five dominant animals in freshwater biomes?
The five dominant animals in freshwater biomes are fish, amphibians (such as frogs and salamanders), insects (such as dragonflies and mosquitoes), birds (such as ducks and herons), and mammals (such as beavers and otters).
As land plants evolved what generation become more dominant A Gametophyte B Sporophyte C both D neither?
In lower plants gametophytic generation was dominant and as the evolution progressed the gametophytic generation became progressively reduced and ultimately became dependent on sporophytic generation. Thus as the evolution progressed sporophyte become more dominant.
Are freckles dominant recessive or dominant dominant?
Freckles are considered a dominant trait, as they are caused by a dominant allele. This means that individuals only need to inherit one copy of the allele from either parent in order to have freckles.
What were the dominant species during the Cenozoic era?
There was no one dominant species throughout the Cenozoic, as it was a period of time that stretched from the extinction of the dinosaurs 65 million years ago to the present day, with many changes in climate that would hinder the ability of any one species to be dominant. However, it is perfectly sensible to say that mammals were dominant since the start of the Cenozoic. Mammals at the time of the dinosaurs (the Jurassic and Cretaceous, mostly) were mostly very small scavengers and herbivores. The extraterrestrial impact and flood basalt outpourings that killed the dinosaurs and many other species left mostly animals under 10kg in weight - chief among them the mammals. With no larger predators to kill them, the mammals took the evolutionary opportunity and flourished, leading us to become the dominant species we are today.
Mammals became dominant only after?
after dinsaurs became extinct
During which era did mammals become common?
Mammals became the dominant land animals in the early Paleocene period of the Cenozoic era, after the extinction of the non-avian dinosaurs at the end of the Cretaceous period of the Mesozoic era.
What was the dominant animal of the Eocene Epoch?
The dominant animal of the Eocene Epoch was the early mammals, which included large herbivorous mammals like the brontotheres and early primates. This period marked a significant diversification and expansion of mammalian species in response to the changing environment.
Most mammals during the Mesozoic were?
During the Mesozoic Era, most mammals were small, nocturnal, and likely insectivorous. They were overshadowed by larger reptiles like dinosaurs and did not become the dominant group of animals until after the extinction of the dinosaurs at the end of the Mesozoic.

What are the dominant organisms or the tertiary period?
During the Tertiary Period the dominant organisms were mammals. These mammals included the many different types of dinosaurs that were roaming the earth 65 million years ago. Other organisms included bony fish such as bass and trout, flowering plants, insects, and birds.
