A 40- to 50-million-year-old cockroach in Baltic amber . Cockroaches are members of the superorder Dictyoptera, which includes the termites and mantids, [5] a group of insects once thought to be separate from cockroaches. Currently, 4,600 species and over 460 genera are described worldwide.
Blattodea includes approximately 4,400 species of cockroach in almost 500 genera, and about 3,000 species of termite in around 300 genera. Termites are pale-coloured, soft-bodied eusocial insects that live in colonies, whereas cockroaches are darker-coloured (often brown), sclerotized, segmented insects. Within the colony, termites have a caste ...
Cockroaches are experts at surviving indoors, hiding in kitchen pipes or musty drawers. A new study uses genetics to chart cockroaches' spread across the globe, from humble beginnings in southeast ...

Scientists have identified the oldest living species on Earth is a deep sea organism that hasn't evolved in more than two billion years. And, it may prove Charles Darwin's Theory of Evolution.
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
The digested particles traveled down the digestive canal, crossed the fusion boundary and entered into the digestive tract of the other animal — “and the other individual could poop out the ...
