No, all embryos of every species are not identical. While many embryos share similar developmental stages due to common evolutionary ancestry, they exhibit distinct characteristics that reflect their species' unique genetic and developmental pathways. For example, vertebrate embryos may show similarities in early stages, but as they develop, species-specific traits become evident. Thus, while there are commonalities, each species has unique embryonic features.
Fruit Flies and frog eggs are long-time,well characterized standbys in the lab environment,and specific manipulations allow researches to introduce genes from other organisms into these species
It is incredibly rare but theoretically possible for decaplets (10 identical siblings). It would require all 10 embryos to split at the same time during fertilization which is highly unlikely.
If there was no change in species over time, then all fossils of that species would be identical.
Charles Darwin did recognize and categorize numerous species during his career. He also recognized that not all species were identical in all of their outward physical characteristics. He also realized that organisms of the same species were identical. He also observed that organisms living in different places with similar environment were different yet similar, thus concluding that they had the same ancestors.
otters form a cult in which every otter places there unfertilized embryos in a circle and the all have a cirlcle jerk and blow massive loads into the center which in retrospect fertilizes all the embryos. giving the otters a very diverse gene pool.
All chordates embryos have pharngeal slits.
Nine-banded armadillos usually have identical quadruplets. One egg is fertilized and it later divides into 4 embryos.
No, not all animals within the same species are identical in appearance. Variations can occur due to factors such as genetic diversity, environmental influences, age, and sex. For example, within a species, there may be differences in size, coloration, and markings. These variations can help individuals adapt to their habitats and enhance survival.
Embryos provide evidence for evolution by showing similarities in early development among different species, suggesting a common ancestry. This supports the idea that all living organisms have evolved from a shared ancestor over time.
They are all the same species so they all require identical treatment and conditions to breed successfully.
the 2 things that ALL growing embryos need are food and oxygen
The same genetic code produces those enzymes
