What is an example of a convergent trait?
For example, hummingbird hawk moths (a type of insect) strongly resemble hummingbirds and have wings that allow them to hover while collecting nectar from flowers. While both species are distinct, their wings shapes converged on a similar evolutionary trajectory.
What are convergent organs?
Convergent evolution is the process in which organisms that are not closely related independently evolve similar features. Adaptions may take the form of similar body forms, colors, organs and other adaptions which make up the organism’s phenotype.
What are the difference between convergent and divergent evolution?
Convergent evolution shows how species have evolved separately but have similar (analogous) structures. Divergent evolution demonstrates how species can have common (homologous) anatomical structures which have evolved for different purposes.
What is the description of convergent?
Definition of convergent 1 : tending to move toward one point or to approach each other : converging convergent lines a tropical cyclone characterized by convergent airflow.
What is convergence in biology?
In evolutionary biology, convergence pertains to an evolutionary process wherein organisms evolve structures that have similar (analogous) structures or functions in spite of their evolutionary ancestors being very dissimilar or unrelated. It is also called convergent evolution.
What’s the difference between convergent and divergent boundaries?
Divergent boundaries — where new crust is generated as the plates pull away from each other. Convergent boundaries — where crust is destroyed as one plate dives under another.
Which feature is formed at convergent plate boundaries?
Trenches. Trenches are geological features formed by convergent boundaries. When two tectonic plates converge, the heavier plate is forced downward, creating a subduction zone. This process results in the formation of a trench.
What is convergent speciation?
Speciation is a result of divergent evolution and occurs when one species diverges into multiple descendant species. Darwin’s finches are an example of this. Convergent evolution occurs when species have different ancestral origins but have developed similar features.
What geological features occur at convergent boundaries?
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.
What landforms do convergent boundaries make?
Typically, a convergent plate boundary—such as the one between the Indian Plate and the Eurasian Plate—forms towering mountain ranges, like the Himalaya, as Earth’s crust is crumpled and pushed upward. In some cases, however, a convergent plate boundary can result in one tectonic plate diving underneath another.
What features are found at a divergent boundary?
Effects that are found at a divergent boundary between oceanic plates include: a submarine mountain range such as the Mid-Atlantic Ridge; volcanic activity in the form of fissure eruptions; shallow earthquake activity; creation of new seafloor and a widening ocean basin.
What are the geological features events of convergent boundary?
The geologic events that occur at convergent boundaries include volcanic activity, earthquakes, mountain formation, and subduction.
What are the features of a divergent plate boundary?
Divergent plate boundaries are characterized by shallow earthquakes, volcanic eruptions, a high topographic ridge, and very young lithosphere.
What type of features are found at a convergent boundary continental oceanic?
Strong earthquakes, volcanic mountains or volcanic arc mountain ranges are what the Convergent boundary forms on the surface when the sinking oceanic plate melts. Other features include ocean trenches, island arcs, submarine mountain ranges, and fault lines all form along tectonic plate boundaries.
What is convergent in biology?
In evolutionary biology, convergent evolution is defined as the process whereby distantly related organisms independently evolve similar traits to adapt to similar necessities.
